Tokyo, Japan, September 16, 2010 — Sumitomo Electric Industries, Ltd. (TOKYO: 5802) (ISIN: JP3407400005), a leading provider in advanced optical solutions, today announced that it is expanding its optical transceiver portfolio with the introduction of a 40GbE optical transceiver for 40km reach. The optical transceiver that Sumitomo Electric developed complies with the CFP Multi-Source Agreement (MSA) hardware and software specification and is capable of supporting 40km link distance over standard single mode fiber.

Sumitomo Electric has already released the 40GbE CFP optical transceiver for 10km reach and in addition, developed the world’s first 40GbE CFP for 40km reach by using a high speed 4-wavelength Corse Wavelength Division Multiplexing (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.
