RedClover Networks, a start-up based in Sunnyvale, California with a subsidiary in Ottawa, Canada, announced a new performance benchmark for 10 Gbps NRZ optical data transmission. RedClover has pushed the reach of its Transdaptor interface sub-systems beyond 240 km over SMF-28 fiber, without the need for any additional NRZ data encoding, spectral shaping, forward-error-correction (FEC), or dispersion-compensating fiber (DCF) modules. In addition, RedClover has demonstrated that, when used in conjunction with the company’s Transdaptor products, conventional 80 km 10 Gbps transponders can have their reach extended to greater than 150 km. RedClover said its technology could provide plug-and-play replacement for conventional 10 Gbps transponders, thereby improving access, storage, metro, CATV, or long-haul optical networks.

- In March 2003, RedClover introduced its “Transdaptor�? family of highly integrated and adaptive universal transponders. The product line includes a 10 Gbps universal transponder module that combines the functionality of a standard SFI-4 electrical interface, 10 Gbps optical interface, and ultra-compact embedded adaptive fiber transmission impairment compensation. It also includes a WDM Optical Transdaptor that adds the functionality of a tunable laser for full C-band or L-band operation. Both products are compliant with 300 pin MSA standards, and support multiple data rates: 9.95 Gbps (OC-192, 10GE WAN), 10.3125 Gbps (10GE LAN), 10.664 Gbps and 10.709 Gbps for different FEC applications. RedClover has targeted its Transdaptor family of interface products at intelligent optical hardware for access, storage, switching, and transport networks. Separately, RedClover announced partnerships with Ixia and with Oki Electric Industry Co. focused on 10 Gbps and 40 Gbps optical interface components and subsystems.
