10G XFP BIDI 40KM

ASCENT’s XFP-LP-2733-40 andXFP‑LP‑3327‑40 Small Form Factor 10 G (XFP) transceivers are compliant with the current XFP Multi-Source Agreement (MSA) Specification. They feature a 1330 nm or 1270 nm DFB transmitter, and a 1270 nm or 1330 nm receiver. They can carry a 10 Gbps data signal up to 40 km over a 9/125 µm SMF wire. Digital diagnostics functions are available via a 2-wire serial interface, as specified in the XFP MSA. The transceiver is RoHS compliant and lead-free per Directive 2002/95/EC3. 10GBASE‐LR/LW Ethernet, SONET OC‐192, SDH STM I‐64.1, 1200‐SM‐LL‐L 10G Fiber Channel, The metal housing ensures low EMI interference standards, with connector retainer.
