Telstra Tests 1 Tbps with Ericsson

Telstra has conducted the first trial of 1 Tbps technology in Australia over 995km of an existing optical fiber network using Ericsson's equipment.

Ericsson recently announced it will provide Telstra with the SPO 1400, the latest packet optical transport platform (POTP) for the metro and the MHL 3000 for long-haul applications with 100Gbps service support. The trial tested a 1Tbps line card in the MHL 3000.

The companies said this successful test over the 995 kilometer optical link between Sydney and Melbourne in Australia shows it is possible to deploy 1 Tbps technology in a real network environment.  Furthermore, when 1 Tbps is commercialized, operators will be in a position to deploy it to meet their capacity requirements.

"The trial has proven that our existing optical cable plant can support Tbps channels along with 40Gbps and 100 Gbps channels simultaneously on the same fibre, verifying that we have the ability to increase capacity on our existing fiber cables when required." Alessandro Pane, Head of Ericsson R&D Optical Transmission, says: "Like so many developed countries, Australia is a very technologically advanced market and Australians are sophisticated users of broadband and mobile technology. In addition, there is widespread smart phone, tablet, IPTV and HDTV take-up. Supporting all these services requires an ever-growing capacity in backhaul and inter-city transmission.

OneChip Photonics Intros 100G PIC in Indium Phosphide

OneChip Photonics introduced a Photonic Integrated Circuit (PIC)-based 100 Gbps device that monolithically integrates all of the optical functions required for an optical transceiver into a single Indium Phosphide (InP)-based chip. All of the active components (Distributed Feedback “DFB” laser, Electro-Absorption Modulator “EAM,” and Waveguide Photodetector “WPD”) and passive components (Wavelength Division Multiplexing “WDM” combiner, splitter and Spot-Size Converter “SSC”) of the chip are, uniquely, integrated in one epitaxial growth step – without re-growth or post-growth modification of the epitaxial material.

The company said its Multi-Guide Vertical Integration (MGVI)-based PICs will enable transceiver manufacturers to produce high-speed, low-power and small-size modules for Data Center Interconnect (DCI) applications.

The MGVI platform in Indium Phosphide is based on the same process that inherently produces the best and fastest Heterojunction Bipolar Transistors (HBTs) used in Radio Frequency Integrated Circuits (RFICs). As such, the company also will be able to integrate electronics, such as Transimpedance Amplifiers (TIAs) and modulator drivers, within a commercially available and volume-scalable process. The silicon photonics dream of leveraging high-volume electronic chip production, while combining photonics and electronics onto the same substrate, is ironically best realized in Indium Phosphide.

Menara Announces Metro 100G Tunable DWDM Transceiver with OTN and FEC

Menara Networks introduced a 100G "System-in-a-Module" that integrates OTU4 framing, ultra FEC, full C-band tunability and 100GE performance monitoring in a 100% MSA compliant CFP form factor with a standard CAUI interface.

"Menara Networks continues on its march to simplify the optical network and help carriers and data center operators bridge the gap between the growing network cost and the declining revenue per bit," said Siraj Nour ElAhmadi, Menara Co-Founder and CEO. "We continue to believe that WDM transmission is a cost and not a revenue center to service providers. Our latest DWDM 100G "System-in-a-module" OTN CFP brings the same level of disruption to the economics, size and power of 100G WDM transmission as our OTN XFP did to 10G transmission."

Menara's patented "System-in-a-Module"  maps a 100GE payload into an ITU G.709 compliant OTU4 frame while offering non-intrusive monitoring of the Ethernet frame statistics. ITU G.975.1 compliant forward error correction is supported with configurable coding gain up to 9.4dB for use over amplified DWDM systems. The OTU4 signal is then transmitted using optical duo-binary signal (ODB) dispersion tolerant modulation over 4 optical channels on the ITU 50 GHz grid. Each of the four channels can be independently tuned over any of the 102 channels supported on ITU 50 GHz grid.

Furthermore, Menara offers a PRBS line performance checker/generator, an extensive set of OTU4 Performance monitoring pints and alarms and has a built-in OTN SNMP MIB accessible through the front Ethernet face plate for ease of configuration and management.

Menara confirmed that it has received an order from a Tier-1 system vendor for this product.

Menara is also announcing the Armada 1000-GM, a 1RU 100G WDM transport solution that offers 100G transponder and 10G/40G muxponder functions into a tunable CFP based OTU4 100G uplink. The compact Armada 1000-GM also includes integrated EDFA optical amplifiers and dispersion compensating modules offering a complete 100G DWDM transmission solution for metro and data center interconnection applications in a compact 1 RU footprint.
