Accelight’s SFP28 BiDi series optical transceiver is designed for fiber communications support 24.33Gbps and 25.78Gbps with CDR engaged, while, 10G Ethernet optical data communication can be supported when CDR is bypassed. It is with the SFP+ 20-pin connector to allow hot plug capability. 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 preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
