Optelian adds 10-Gbps OTN regenerator

OCTOBER 14, 2009 -- Optelian, a designer and manufacturer of optical transport systems, is offering enhanced OTN capabilities with the release of the new RGN-10XO 10-Gbps, G.709-compliant regenerator module.

"Many network operators will use OTN only for its forward-error-correction (FEC) capability when they are provisioning longer spans," says Dave Mills, vice president, sales, for Optelian. "As we move forward, OTN’s enhanced fault isolation and performance monitoring will be adopted to save troubleshooting costs and support service-level agreements with end-user customers."

The RGN-10XO can act as a mid-span OTN regenerator or a demarcation point regenerator between an OTN and non-OTN network. It can also act as a transponder, wrapping a short-reach 1,310- or 1,550-nm native client signal into a long-reach OTU-2 signal. It has pluggable XFP interfaces for use in a variety of applications including CWDM and DWDM systems.

The RGN-10XO complements the MPX-3GOTN muxponder in LightGAIN's OTN product line. Both modules offer overhead monitoring capabilities, including SONET/SDH B1/B2 and OTN SM/PM/TCM BIP-8 error reporting and trace insertion, as well as mismatch alarming. Both standard FEC and super FEC are provided, along with fast protection switching based on electrical signal quality.

Synchronous timing regeneration on the RGN-10XO ensures the signal's timing is transparently transported and maintained independently for each direction. In addition to supporting OTN transport of OC-192 and STM-64 client signals, OTU-2 overclocking is supported for OTN transport of 10-Gigabit Ethernet LAN and 10-Gigabit Fibre Channel client signals.
