Sumitomo Electric intros 10G CWDM SFP+ with Internal CWDM DFB LD chip

OCTOBER 29, 2008 -- Sumitomo Electric Industries Ltd. (search for Sumitomo) is expanding its 10-Gbit/sec portfolio with the introduction of a CWDM SFP+ transceiver module that can provide parallel transmission at 80 Gbits/sec.

The new module uses Sumitomo Electric's 10-Gbit/sec CWDM DFB LD chip and supports 80-Gbit/sec (eight channels from 1470 to 1610 nm) parallel transmission.

This 10-Gbit/sec CWDM SFP+ module is MSA compatible and allows up to 48 ports per line card, thereby reducing cost per bit. The internal DFB LD chip manufactured through enhanced processes achieves lower reduced parasitic capacitance than the existing one, according to the company. The module covers a center wavelength from 1470 to 1610 nm with a 20-nm spacing. Since transmission distance is less than 10 km, power penalty due to chromatic dispersion can be negligible, so competitive direct modulation can be used for this CWDM SFP+ module, the company concludes.

Sumitomo Electric plans to launch this 10-Gbit/sec CWDM SFP+ module in the market in 2009.
