Sumitomo Electric Industries is expanding its optical transceiver portfolio with the introduction of a 40GE optical transceiver for a 40-kilometer reach.
The optical transceiver complies with the CFP multi-source agreement hardware and software specification and is capable of supporting 40-km link over standard single mode fiber.
Sumitomo Electric developed the world's first 40GE CFP for 40km reach by using a high speed 4-wavelength CWDM laser diode for the optical transmitter and a high-speed avalanche photo diode for the optical receiver.
Maximum power consumption is compliant with CFP MSA power class 1 (8W max) and it is the same value as the 40GbE CFP for 10km reach, which Sumitomo Electric has already released.
