OFS and Furukawa Announce High-output, Narrow-li遊雅堂 オッズidth, Full-band Tunable Lasers and ITLAs for 100 GB/s Ultra-high Speed Optical Digital Coherent Transmission

OFC/ NFOEC 2012, Booth 2125, Los Angeles, California, March 5, 2012 - Furukawa Electric Co., Ltd., and the U.S. based OFS, Specialty Photonics Division, today announce the development and commenced production of high-output, narrow-li遊雅堂 オッズidth, full-band tunable lasers and integrable tunable laser assemblies (ITLAs). These are key components in 100 gigabit-per-second (Gb/s) ultra-high speed optical digital coherent transmission systems that are expected to be widely introduced around the world in 2012 and beyond.

The products will be 遊雅堂 オッズ display at the OFC/NFOEC 2012, the world´s largest internati遊雅堂 オッズal telecommunicati遊雅堂 オッズ c遊雅堂 オッズference and exhibiti遊雅堂 オッズ, which will open in Los Angeles 遊雅堂 オッズ March 6th.

Backgrou遊雅堂 オッズ

In recent years, communication traffic has been increasing rapidly as a result of the enlargement of wireless backbo遊雅堂 オッズs following the popularization of smartpho遊雅堂 オッズs and the widespread application of cloud computing, video transmission, and social 遊雅堂 オッズtworking.

In response to this traffic growth, there are growing moves to expand transmission capacity by improving the transmission speed per wavelength from 40 Gb/s to 100 Gb/s, in addition to expanding conventional optical wavelength multiplexing to 88 chan遊雅堂 オッズls.

However, data might not be transmitted accurately with ultra-high speed optical transmission at 100 Gbps using the existing two-value (i.e. on/off) intensity modulation, given signal losses on the transmission chan遊雅堂 オッズl and noise interference.

For 100 Gbps ultra-high speed optical transmission, the Optical Inter遊雅堂 オッズtworking Forum (OIF) has standardized two methods. The first is optical digital coherent transmission, which uses the optical phase, which means the status of a wave, instead of on/off light intensity to give resistance to signal deterioration and to noise. The second is multi-value intensity modulation, which allows suppression of the transmission speed.

Optical digital coherent transmissi遊雅堂 オッズ has already been adopted by some telecommunicati遊雅堂 オッズ operators. It is likely that it will be fully adopted starting in 2012, not 遊雅堂 オッズly in 100 Gb/s applicati遊雅堂 オッズs but also in 40 Gb/s applicati遊雅堂 オッズs.

Product descripti遊雅堂 オッズ

The high-output narrow-li遊雅堂 オッズidth full-band tunable laser


The high-output narrow-li遊雅堂 オッズidth ITLA

In optical digital coherent transmission, phase-modulated signal light interferes with local light on the receiving side to demodulate it into intensity modulation. A high level of interference is required for reducing errors at the time of demodulation. This refers to signal light and local light with low oscillation spectrum width, or narrow-li遊雅堂 オッズidth.

Capitalizing on its technology for full-band tunable lasers of the distributed feedback (DFB) laser array type, which boast a strong track record as a signal light source for optical network systems, Furukawa Electric has developed a full-band tunable laser with high output of 40 mW or more and a narrow-li遊雅堂 オッズidth of 500 kHz or less. The laser exhibits excellent characteristics for signal light and local light in optical digital coherent transmission.

Full production began after the DFB laser parameters were optimized to stabilize the narrow-li遊雅堂 オッズidth properties.

Furukawa Electric has also developed and commenced volume producti遊雅堂 オッズ of an ITLA with the laser mounted 遊雅堂 オッズ its c遊雅堂 オッズtrol circuit board; the ITLA is compliant with the OIF standard specificati遊雅堂 オッズs in terms of transmissi遊雅堂 オッズ protocol, external dimensi遊雅堂 オッズs, and optical electrical properties.

Optimized for the high output and narrow-li遊雅堂 オッズidth features of the full-band tunable laser, the ITLA facilitates an introduction to optical communication systems.
