ADVA Optical Networking Demonstrates Serial 100 Gbps Transmission

ADVA Optical Networking has developed a novel DPSK-3ASK (Differential Phase-Shift Keying, 3-level Amplitude-Shift Keying) modulation format for serial 100Gbps transmission over a single wavelength channel. Engineers at the company's labs in Meiningen, Germany, have successfully demonstrated for the first time this new modulation scheme, which utilizes available 40 Gbps components and facilitates operation on a standard ITU (International Telecommunication Union) channel grid.

ADVA noted that existing serial 100Gbps proposals such as DP-QPSK (Dual-Polarization Quadrature Phase Shift Keying) have been optimized for (ultra-) long haul transmission. Their complexity, cost and power consumption make them less suitable for metro applications. Given the substantial challenge of achieving reasonable link distances at 100Gbps due to chromatic dispersion and polarization mode dispersion, most industry work on short distances to date has centered on multi-fiber and multi-lambda approaches. The IEEE, ITU-T and OIF have all been working on 100 Gbps standards, with the focus currently placed on the two extremes of transmission distance.

ADVA said its DPSK-3ASK solution is complementary to existing 10- and 40 Gbps designs and fits in existing installed network architectures, making it easier to upgrade and operate. Its direct detection alleviates the need for power-consuming, high-speed digital signal processing as typically required for long-haul schemes. It is compatible with DWDM systems like the ADVA FSP 3000, and when coupled with optical amplification facilitates metro/regional transmission distances up to 600km.

This work by ADVA Optical Networking was partially funded by the German Ministry of Education and Research (BMBF) and is part of the CELTIC 100GET-METRO project. Get more information on ADVA Optical Networking's participation in this project.

"Current industry standardization efforts have left a gap between 40km and 600km, which leaves a sizeable portion of the market unaddressed. Our solution targets exactly that sweet spot," stated Dr. Christoph Glingener, chief technology officer (CTO) for ADVA Optical Networking. "In addition, this solution utilizes off-the-shelf componentry, which enables it to be implemented sooner and with minimal industry investment, lessening the burden on optical component companies in a difficult market environment."

Opnext Introduces Optical Transceiver for 100 Gbps Ethernet

Opnext announced the industry's first 100 Gbps Ethernet (100GbE) optical transceiver for 10km transmission over standard single-mode fiber (SMF). The transceiver is compliant with IEEE P802.3ba 100GBASE-LR4 standard and with the CFP Multi-Source Agreement (MSA). This MSA is the first industry standard to support next generation high speed interfaces including 100GbE transmission.

Opnext's 100GbE optical transceiver utilizes an in-house 1310nm wavelength range 25 Gbps EA-DFB laser (electro-absorption modulator with integrated distributed feedback laser) TOSA and in-house PIN-PD ROSA. Both the TOSA and ROSA were developed in collaboration with the Central Research Laboratories of Hitachi, Ltd.

Opnext said the low power consumption of this transceiver was achieved by using a high temperature operation EA-DFB laser based on Opnext and Hitachi's advanced technologies of using semiconductor material with a temperature-tolerant band-gap structure. In addition, the cost-effective structure and compact size of the transceiver was achieved with non-coaxial 25 Gbps connections between the TOSA, ROSA and GearBox IC.

"The availability of the 100GbE 10km client-side optical transceiver is key for wide spread 100GbE applications," said Kei Oki, president of Opnext Japan. "This successful demonstration exemplifies our relationship with Hitachi CRL and demonstrates Opnext's ability to drive technology within the industry."

The optical transceiver is hot pluggable and is the same length but double the width of the 10 Gbps Ethernet industrial standard XENPAK. It has SC duplex receptacle optical connecter and a 148-pin electrical connecter with CAUI 10x10 Gbps signals. The transceiver requires a single +3.3V power supply. Samples will be available in mid 2009 and will be in generally available in mass production in mid 2010.

NSN Enhances hiT 7300 Optical Platform

Nokia Siemens Networks released version 4.25 of its hiT 7300 optical platform featuring 40 Gbps capabilities in a compact (seven modules per sub-rack) chassis. The hiT 7300 is a DWDM platform capable of serving both metro and core needs. The enhancements increase flexibility to support more revenue generating services such as high definition video on demand and IPTV allowing operators to expand their services.

In release 4.25, this flexibility is accomplished by a single blade Add-Drop Multiplexers (ADM). This ADM card supports standard point-to-connections, along with all topologies needed for broadcasts and multicasts and all common aggregation applications, such as mobile backhaul.

The new 4.25 release delivers further technical enhancements by maximizing the utilization of existing fiber in the networks. Specifically, the hiT 7300 offers an optional (Polarization-Mode-Dispersion-Compensator (PMDC)) which helps older, lower-quality or stressed fibers achieve up to three times their current reach. The platform has a reach of up to 1600 kilometers.

"The upgrades we've made to the hiT 7300 are a response to what we hear from customers every day - and we've already seen strong pre-release demand for the latest product," said Uwe Fischer, Nokia Siemens Networks' DWDM business line. "By further developing the hiT7300 we're helping operators where it matters most, reducing cost for spares, operation and maintenance, training, network management, space and power consumption, while increasing flexibility in the network."

OKI Develops 160 Gbps Next Gen PON

OKI Electric Industry has developed a 160Gbps ultra high-speed optical next generation access (NGA) asymmetric PON system using hybrid Optical Time Division Multiplexing (OTDM) and Optical Code Division Multiplexing (OCDM).

Existing passive optical access systems are operated at 1.25Gbps in Japan and 2.5 Gbps in the US, Europe and elsewhere. OKI noted that in such optical access systems, the communication capacity per user when 16 users are connected, is limited to 78 to 156Mbps.

The ultra high-speed NGA Asymmetric PON system developed by OKI achieves 128-times larger capacity than that of GE-PON systems and 64-times larger capacity than GPON systems. This means that with 16 users, telecom carriers can offer a 10 Gbps capacity for each user.

The Optical Line Terminal (OLT) used in the system processes 10Gbps signals using a 16-chip encoder and then optically multiplexes them into a 25ps TDM slot. OKI quadrupled the signal with wavelength to output a multiplex signal of 10Gbps x 16 ch. OKI then transmits this 160 Gbps signal over a 20km distance (the longest in an optical access system). The signal is then divided with a 1 x 16 splitter. An ONU then extracts and decodes the 10Gbps signal.

The research that led to OKI's achievement was conducted as part of the "Research and development for ultra high-speed optical NGA Asymmetric PON system," under the auspices of NICT's "Basic Technology Promotion System for Private Sectors Program.
