Optical module and component manufacturer Opnext Inc of Eatontown, NJ, USA has announced the availability of its DWDM-XFP and DWDM-X2 pluggable modules, which complement its existing 10Gb/s DWDM 300-pin and XENPAK portfolio by delivering a smaller size and power footprint to DWDM networking applications.

The TRF7061FN DWDM-XFP and TRT7063EN DWDM-X2 wavelength-specific pluggable modules are offered at ITU-T 100GHz channel spacing. The module transmitter exceeds industry requirements of 80km of standard single-mode fiber or 1600ps of dispersion.

Both modules provide the cost and power savings inherent to the XFP and X2 form factors, enabling cost-effective 10Gb/s optical links for long-reach and metropolitan-area DWDM applications. The small footprint and low power consumption of a maximum of 4W enable what is claimned to be the highest-board-density 10Gb/s applications in the industry. The XFP product is protocol independent and operates at multiple data rates, from the SONET 9.95Gb/s data rate to the 10GbE + FEC data rate of 11.1Gb/s.

“As energy costs continue to increase, Opnext has committed itself to producing components with low power consumption,” says Takayuki Kanno, executive VP of the firm’s modules business unit. Opnext’s new pluggable transceiver modules for 10Gb/s DWDM applications over 80km fiber also maximize system scalability and increase operational flexibility, enabling customers to offer systems that minimize the initial cost of the network, he adds.

Opnext offers a full line-up of short-reach to DWDM in XFP and X2 modules for metropolitan core, metropolitan regional and metro access systems. The 10Gb/s module transceivers fully comply with industry standards from ITU-T G.691, G.709, and IEEE 802.3, and OIF recommendations, supporting electrical interfaces including SFI-4, XAUI and XFI, which ease integration onto system host boards. Opnext says that its transceivers also meet or exceed standards established by industry multi-source agreements (MSAs).
