Sumitomo Electric Industries Ltd. is now shipping in production volumes small form-factor pluggable optical transceivers for coarse wavelength-division multiplexing applications.
The transceivers are available in eight ITU-compliant coarse wavelength-division multiplexing wavelengths from 1470 nm to 1610 nm. Transceivers for eight additional wavelengths in the 1300-nm region will be available later this year.
Using high-performance, uncooled DFB lasers and optimum thermal design of devices and circuitry, the transceivers are designed to combine excellent
transmission characteristics and low cost.
The transceivers are designed to support 1.25 Gb/s Gigabit Ethernet, 2.5 Gb/s STM-16/OC-48, and 2.7 Gb/s STM-16/OC-48 with FEC, and achieve transmission distances of 40 km with a PIN photodiode receiver or 80 km with an APD.
The transceivers include built-in digital diagnostic functions and operate from a single 3.3-Vdc supply. They comply fully with the SFP multisource agreement.
Sumitomo Electric Industries, based in Tokyo, designs, manufactures and sells optical fibers and components. For more information visit www.sei.co.jp.
