WST-S28-BX1-xx series single mode transceiver is a small form factor pluggable module for bi-directional serial optical data communications such as 25GBASE-BR10 Ethernet and CPRI Option 8/10. It is with the SFP28 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. The transmitter section uses a 1270 / 1330 nm multiple quantum well DFB laser and is a 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 rate selection clock data recovery (CDR) IC.
