Finisar Delivers Narrowly Tunable, Long-Reach 10 Gbps Optical Transmitter

Finisar announced general availability of its 10 Gbps DM80 and DM200 narrowly tunable CMLTM Butterfly Transmitters for DWDM transponders and telecom line card applications.



The new devices employ the directly modulated Chirp Managed Laser (CML) technology recently acquired by Finisar. The DM200 transmits with an output power of 0 to 3 dBm and can transmit at 10 Gbps over distances of 300 km without requiring costly optical dispersion compensation. For applications requiring high output power, the DM80 can transmit distances up to 120 km with an output power of 4-7 dBm.



Both the DM80 and DM200 transmitters offer narrow tunability at either 4-channel, 100 GHz DWDM spacing or 8-channel, 50 GHz DWDM spacing across both C-band and L-band, thus reducing the supply chain complexity by a factor of 4x or 8x compared to non-tunable sources. http://www.finisar.com
