Ascent Communication Technology

10G XFP BIDI 80KM

Ascent’s XFP-LP-4955-80 module is compliant with the 10G Small Form-Factor Pluggable (XFP) Multi-Source Agreement (MSA), supporting data-rate of 9.953 to 11.1Gbps, and transmission distance up to 80km on SMF. The transceiver module comprises a transmitter with 1490nm Cooled EML laser and a receiver with an APD photodiode. Transmitter and receiver are separate within a wide temperature range and offers optimum heat consumption and excellent electromagnetic shielding thus enabling high port densities for 10 GbE systems. The metal housing ensures low EMI interference standards, with connector retainer. 10GBASE‐ZR/ZW 10G Ethernet, SONET OC‐192/SDH, SDH STM I‐64.1, 10G Fiber Channel
