Description

The SFP+ BWDM series single mode transceiver is small form factor pluggable module for duplex optical data communications such as 10GBASE-LR/LW defined by IEEE 802.3ae. It is with the SFP+ 20-pin connector to allow hot plug capability.

The SFP+ BWDM module is designed for single mode fiber and operates at a nominal wavelength of 1270nm; The transmitter section uses a multiple quantum well DFB, which is class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector (IDP) mounted in an optical header and a limiting post-amplifier IC.
