'Smallest' 10-Gbit widely tunable transponder

XLight Photonics, a Tel Aviv-based manufacturer of tunable fibre-optic subsystems for metro and long-haul DWDM systems, has developed the XL-TT10G, a widely tunable transponder supporting multiple 10-Gbit/sec data rates in a small-sized 300-pin multisource-agreement (MSA) package. The XL-TT10G tunes over the entire C- or L-bands with wavelength spacing of 50 or 100 GHz. It is available in a small MSA form factor of 100¥90¥15 mm and supports multiple data rates between 9.95 and 12.5 Gbits/sec. The transponder is offered with an APD or PIN receiver and X or Z cut modulator (0 or -0.7 chirp). The transponder wavelength is tuned by using the standard I2C communications link and commands or the three tuning control pins (LsTune) in the MSA connector or by tuning it offline using Atlas, XLight's evaluation board and control software.

As Lightwave Europe went to press, the merger of XLight with fellow Israeli company Civcom was announced..The combined entity says it expects to become "a major force in the market for tunable, dynamic optoelectronic components."
