OCTOBER 6, 2008 -- StrataLight Communications Inc. (search for StrataLight Communications) today announced an extension of its DPSK product line to support L-band (1570.42-nm to 1607.42-nm) wavelengths.
Adding the L-Band capability to StrataLight's DPSK muxponder, transponder, and regenerator continues the OTS-4000 design philosophy of simplifying network deployments by allowing for 40 Gbits/sec to plug and play in 10G designed networks, say company representatives. The increased useable bandwidth that results meets the demand for higher line rate services and lowers capital expenditures.
StrataLight's L-Band OTS-4011-L multiplexing transponder has been deployed by Xtera Communications (search for Xtera Communications) to meet the demand for 40 Gbits/sec on an unrepeatered link of a Tier-1 carrier in North America.
"For some service providers, the L-Band is an option that enables significant capacity increases on existing networks," explains Herve Fevrier, COO of Xtera Communications. "For others, the L-Band is the only choice to overcome fiber impairments. In some subsea applications, the L-Band is necessary to simultaneously maximize capacity and transport distance," he says. "This technology, along with all-Raman amplification, provides a cost-effective solution to evolve those networks to 40 Gbits/sec."
The L-Band product line consists of:
• The OTS-4040-L DPSK -- a full standard-compliant (OTU3, OC-768/STM-256) 40-Gbit/sec client and line transponder;
• The OTS-4011-L DPSK -- a standard-compliant (OTU3, OC-768/STM-256, OTU2, OC-192/STM-64, 10GE LAN/WAN) 4x10-Gbit/sec to 40-Gbit/sec multiplexing transponder (muxponder); and
• The OTS-4400-L DPSK -- a uni-directional 40-Gbit/sec regenerator to further extend the reach of both of the above products.
