Luna sells optical receivers business to MACOM for $29.5m

Luna Innovations, supplier of products for the aerospace, automotive, energy, defence and telecommunications markets, announced that MACOM Technology Solutions has agreed to buy the assets and operations related to its high-speed optical receivers (HSOR) business.

The purchase price includes $29.5 million to be paid in cash at closing and an additional $4.0 million to be held in escrow until December 15, 2018 for possible working capital adjustments to the purchase price and potential satisfaction of certain post-closing indemnification obligations.

The sale includes the operations associated with Luna’s development, manufacturing and sales of products including high-speed integrated coherent receivers and photodiodes. Luna originally acquired these operations as part of its merger with Advanced Photonix, Inc. (API), in May 2015. The assets and employees associated with Luna’s Terahertz operations are not being transferred as part of this transaction.

Through the transaction, employees associated with the company’s HSOR operations and administration in the company's location in Ann Arbor, Michigan, will transfer to MACOM. The Picometrix line of high-speed optical receivers and optical-to-electrical converters serve the global telecommunications, data centre and manufacturing testing industries.

NTT demos 118 Tbit/s transmission on multi-core fibre

NTT, together with six partners, KDDI Research, Sumitomo Electric Industries, Fujikura, Furukawa Electric, NEC and Chiba Institute of Technology (CIT), announced a demonstration of what is claimed as the highest transmission capacity of 118.5 Tbit/s using a multi-core fibre with four optical paths within the same diameter as currently used fibre.

NTT noted that a conventional glass diameter of 125 µm in accordance with the international standard enables the use of existing fibre fabrication and optical connector technologies. The demonstration is designed to validate the concept of multi-core fibre-based long-haul and high capacity transmission system comprising multiple vendor technologies and advance the application of multi-core fibre technology.

In the new fibre, 4-5 cores can be arranged within a 125 µm diameter while maintaining the same transmission quality as current optical fibre, with a 316 km multi-core transmission line realised with a 0.21 dB/km average loss, concatenating standard diameter multi-core fibre with 4 cores fabricated by multiple vendors.

As part of the new design, Sumitomo Electric, Fujikura and Furukawa each fabricated a multi-core fibre with 4 cores and more than 100 km length. All multi-core fibres can be used in the 1260 to 1625 nm wavelength region and provide similar transmission properties to current SMF with mode filed diameter at 1550 nm of 9-10 µm).

The fabricated multi-core fibres were divided into a 20-40 km sections and three transmission spans with a length of 104-107 km were re-constructed by splicing the multi-core fibres provided by different vendors. A satisfactory low loss comparable to conventional SMF was achieved, with average loss of four cores in each span 0.22 dB/km or less, including splicing losses.

In addition, three multi-core optical amplifiers fabricated by NEC, KDDI Research, NTT and Furukawa were inserted at each end of three spans to compensate the signal attenuation. Cladding pumping type multi-core optical amplifiers designed to reduce power consumption were used, enabling a 16% improvement in power usage.

To confirm the performance of the constructed multi-core transmission line to beyond 100 Tbit/s transmission, 16QAM-based 116-wavelength signals were prepared and the output signal quality over 316 km transmission was examined.

Additionally, Fan-In/Fan-Out devices developed by NTT and Furukawa were used to input/output signals to and from each core of the multi-core fibre. Pluggable optical connectors with existing MU-type or SC-type interfaces from CIT and NTT were used to connect the input/output end of the multi-core transmission lines and Fan-In/Fan-Out devices.

The work was partially based on work commissioned by the National Institute of Information and Communications Technology (NICT), and the companies stated that they aim to introduce the standard diameter multi-core fibre by the early 2020s. The achievement was reported in early August as a post deadline paper at the Opto Electronics and Communications Conference (OECC 2017) in Singapore.

Kaiam expands UK manufacturing capacity via acquisition of facilities from CP

Kaiam, a privately-held developer of hybrid photonic integrated circuit (PIC) technology, announced the completion of its acquisition of the manufacturing facilities of Compound Photonics (CP) in Newton Aycliffe, Durham in the UK as part of a transaction that also includes investment by CP into Kaiam to further develop the facility.

The Newton Aycliffe facility will enable Kaiam to significantly increase its manufacturing capacity for silica-on-silicon planar lightwave circuits (PLCs) and 40 and 100 Gbit/s transceivers, and adds both electronic and optoelectronic compound semiconductor devices to the product line. The acquisition also includes tooling and an experienced team that complements and expands Kaiam's existing Livingston, Scotland factory.

Kaiam noted that the new facility will enable it to produce InP photonic integrated circuits (PICs) that will form the basis for advanced transceivers in the future. The transaction continues Kaiam's strategy of achieving vertical integration, building on its acquisition of Gemfire's PLC fab in 2013.

The Newton Aycliffe facility encompasses 300,000 sq feet and includes a fully operational wafer fab with 100,000 sq feet. of cleanroom space for processing, packaging, and testing of III-V devices. The factory is currently shipping GaAs devices and circuits, with the capability to produce InP optoelectronics. Kaiam noted that the facility was originally built as a silicon fab for DRAMs before being converted to III-V materials and currently has 3 and 6 inch lines.
Kaiam announced in March that it planned to acquire the manufacturing facilities of Compound Photonics (CP) in Newton Aycliffe. Kaiam acquired Gemfire, its strategic PLC supplier, in 2013 and currently operates an 8 inch silica-on-silicon line for the fabrication of integrated optical components in Gemfire's Livingston facility in Scotland. It also operates 40 and 100 Gbit/s optical packaging lines at the facility, and noted at the time that these were nearing capacity.

Compound Photonics (CP) is a privately held photonics company with a focus on liquid crystal on silicon display devices and laser technologies for a range of applications in the projection and near to eye display markets.


Commenting on the acquisition, Bardia Pezeshki, Kaiam CEO, said, "… future transceivers that run at higher speed and use complex modulation formats will require integrated photonic elements that are highly differentiated and will not be readily available in the market… this new facility will give Kaiam this essential PIC capability, positioning it to meet customers' needs for improving speed, cost, power, density and manufacturing scale".

LightCounting reports record optical networking market in '16

Market research firm LightCounting finds in its latest Optical Communications Market Forecast report that while demand for optical networking equipment, modules and components attained record levels in 2016, the market was weak in the first quarter of 2017.

LightCounting reports that Huawei led the market in terms of growth in 2016, but significantly reduced purchases of optics in the first quarter of 2017 and forecasts that this weakness is likely to continue in the current quarter. However, the research firm believes that this a temporary slowdown in the optical market.

Looking at data for overall capex of the Top 15 service providers globally, LightCounting notes a sharp decline in Asia in 2016 due to lower spending by the big three Chinese operators, while spending in the U.S. and Europe remained stable versus 2015. Even so, 2016 was a record year for optical communications equipment revenue, which typically accounts for around 10% of service provider capex.

China

China Mobile was the largest consumer of optics in 2016 and added 30 million FTTH subscribers and deployed more than 50,000 ports of 100 Gbit/s DWDM optics into its core network. In addition, upgrades of China Mobile's metro and metro access networks drove demand for 10 Gbit/s optical components and modules. LightCounting notes that while some upgrade projects were completed in 2016, many are ongoing.

The research firm also cites a presentation by China Mobile at OFC 2017, in which the operator said that traffic growth rates in its network rose from 46% in 2013-14 to 88% in 2015-16, compared with a growth global rate of around 30%. Therefore, China Mobile, along with China Telecom and China Unicom, are expected to continue their high levels of spending to address above average traffic growth. LightCounting states that the capex-to-revenue ratio for Chinese service providers is around 25%, compared to 15% for all other operators.

LightCounting estimates that deployments of 100 Gbit/s DWDM ports in China in 2016 translate to a 70% increase in network bandwidth, and predicts that Chinese service providers will increase bandwidth in DWDM networks by a further 40% in 2017. However, it believes that deployments will increase in 2018 to keep pace with traffic growth.

Cloud DCI

Regarding DWDM deployments in the cloud/data centre interconnect (DCI) and enterprise segments, LightCounting observes that while this is a relatively small market in terms of total bandwidth, it is growing much faster that the service provider segment. As a result, bandwidth demand from cloud companies connecting data centres is expected to be very high in 2017.

LightCounting notes that Amazon and Facebook report that traffic inside their data centres is increasing by 100% annually. While growth in traffic between data centres is expected to be slower, based on the rate of construction of new data centres the research firm predicts 100% bandwidth growth for DCI traffic 2017. This increase in DWDM bandwidth demand for cloud DCI is expected to compensate for lower demand in China.

Lightwave Logic Demos Modulation with P2IC enabling 25G

Colorado-based Lightwave Logic, a company developing photonic devices and non-linear optical polymer materials for optical data communications and telecommunications applications, announced it has achieved bandwidth suitable for 25 Gbit/s data rates in an all-organic polymer ridge waveguide intensity modulator prototype.

The company noted that the 25 Gbit/s capability demonstration marks a significant improvement over its initial 10 Gbit/s device modulator that it reported last December.

Lightwave Logic explained that a modulator converts electronic information into light pulses that can traverse optical cables used in data centres, for data communications and high performance computing applications. To achieve a 100 Gbit/s data rate, modulators are typically configured in groups of four, each supporting 25 Gbit/s data rate.

Lightwave Logic's polymer photonics integrated circuit (P2IC) is similar to an electronic integrated circuit, but incorporates two or more optical functions on a single substrate platform. P2IC devices are expected to allow increased component density, with numerous photonic functions enabled using electro-optic polymer materials. This can provide scalable photonic devices offering lower cost together with higher performance.

In December 2016, Lightwave Logic announced it had achieved high-speed modulation utilising its first all-organic polymer ridge waveguide intensity modulator prototype. The company stated that the prototype could enable bandwidth sufficient to support data rates of around 10 Gbit/s, and that it anticipated increasing this performance to 25 Gbit/s.

Recently, Lightwave Logic announced that Dr. Michael Lebby, who established Intel's photonics division, would assume the role of CEO, effective May 1, 2017, succeeding Tom Zelibor who will remain as board chairman. It also recently elected Dr. Fred Leonberger, formerly with JDS Uniphase, to its board.


Commenting on the announcement, Lightwave Logic CEO Tom Zelibor said, "Enabled by the P2IC polymer system, this prototype device is suitable for data rates at 25 Gbit/s, and I believe it can be scaled to operate up to 50 Gbit/s… which would be the key to… addressing the next large market, 400 Gbit/s nodes".

Picometrix to supply 100G Coherent Receivers to Chinese Vendor

Luna Innovations, a developer and supplier of fibre optic sensing and T&M products, announced that its Picometrix division has entered into a vendor managed inventory (VMI) agreement with a major Chinese provider of telecoms equipment and network solutions.

Under the agreement, Picometrix's technology will be more closely integrated into the customer's supply chain and manufacturing processes. As part of the deal, Picometrix will maintain in Hong Kong a dedicated inventory of 100 Gbit/s integrated coherent receivers and other future approved products that the customer will be able to incorporate into its manufacturing operation on a just-in-time basis.

Following the execution of the new VMI agreement, Picometrix has received an order for the supply of coherent receivers for 100 Gbit/s optical transport network equipment. The order is valued at approximately $1.4 million and scheduled to be delivered by June 2017.

Under the agreement, Picometrix expects to supply both its first generation CR-100D product and its next generation, Gen 2, CR-100F coherent receivers. The CR-100F device is the company's latest generation 100 Gbit/s coherent receiver that is compliant with the Optical Internetworking Forum (OIF) Implementation Agreement (IA) for integrated dual polarisation micro-intradyne coherent receivers (ICRs).

Picometrix noted that the Gen 2 CR-100F product is approximately one-quarter the size of its first generation CR-100D and also offers additional features including signal detect and a variable optical attenuator. The customer will deploy the CR-100F for long-haul and metro applications as an upgrade to support increasing bandwidth demand.

Previously, in October 2016 Luna Innovations announced that Picometrix had received a $2.8 million follow-on order from a leading telecoms company for its 100 Gbit/s ICR for applications in long-haul and metro networks.

New QSFP-DD MSA Targets 400G

The Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA) group has released a specification for the new QSFP-DD form factor, which is a next generation high-density, high-speed pluggable module with a QSFP28 compatible double-density interface. QSFP-DD pluggable modules can quadruple the bandwidth of networking equipment while remaining backwards compatible with existing QSFP form factors used across Ethernet, Fibre Channel and InfiniBand for 40 Gbps and 100 Gbps network applications.

Specifically, the new QSFP-DD form factor expands the standard QSFP four-lane interface by adding a row of contacts providing for an eight-lane electrical interface, each operating up to 25 Gbps with Non-Return-to-Zero (NRZ) modulation or 50 Gbps with Pulse Amplitude Modulation (PAM4). This adaptation allows the QSFP-DD form factor to address solutions up to 400 Gbps aggregate per QSFP-DD port, while providing backward compatibility to 40 Gbps and 100 Gbps. A single switch slot can support up to 36 QSFP-DD modules providing up to 14.4 Tbps aggregate capacity. With an advanced thermal design, the new QSFP-DD solution can support modules up to 12W, providing significant system design flexibility.

In total, 52 companies came together in support of the QSFP-DD MSA to address the industry need for high-density, high-speed networking solutions.

QSFP-DD MSA founder-promoters include Broadcom, Brocade, Cisco, Corning, Finisar, Foxconn Interconnect Technology, Huawei, Intel, Juniper Networks, Lumentum, Luxtera, Mellanox Technologies, Molex, Oclaro, and TE Connectivity.

Contributors include Amphenol, Applied Optoelectronics, APRESIA Systems, Celestica, Ciena, ColorChip, Dell EMC, Delta, Fujitsu Optical Components, Genesis, H3C, Innovium, Inphi, Ixia, Kaiam, LEONI, Lorom, Luxshare, MACOM, MaxLinear, MultiLane, NeoPhotonics, Nokia, Panduit, PHY-SI, Ranovus, Samtec, Senko, Semtech, Sicoya, Siemon, Skorpios Technologies, Source Photonics, Spirent, Sumitomo Electric, Xilinx, and Yamaichi Electronics.
