Bookham has launched an MSA compatible 2.5Gb/s transmit optical subassembly (TOSA). The next-generation TOSA is designed for time division multiplexing and wavelength-division multiplexing. It can also be used to replace 14-pin butterfly direct modulated lasers on card applications.
The TOSA has a transmission capability of 125Mb/s to 5.3Gb/s over 1600 to 6000ps/nm dispersion, with low penalty and high extinction ratio of greater than 10dB. At OC48 data rate it has a reach of up to 360km in the C band and 200km and the L band.
