The SY85B5-X1ATNA transceiver from OMC TECH is small form factor pluggable module for serial optical data communications such as IEEE 802.3cc 25GBASE-SR/SW. It is with the SFP28 and SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. This module is designed for multi-mode-fiber (MMF) and operates at a nominal wavelength of 850nm.
Transmitter Section
The transmitter consists of a high-performance 850 nm Vertical Cavity Surface Emitting Laser(VCSEL)in the optical subassembly (OSA), which is housed within a plastic barrel package. In addition, this component is also class 1 laser that compliant with International Safety Standard IEC-60825-1:2014. It complies with EN60825-1:2014/A11:2021 and FDA 21 CFR 1040.10 and 1040.11.
Receiver Section
The receiver contains of a GaAs PIN photodiode that coupled to a high sensitivity transimpedance amplifier (TIA) in an OSA. This OSA combination is mated to a post amplifier IC that provides the post amplification SD (Signal Detection) or LOS (Loss of Signal) indication circuit which provides the logic high state output when an unusable input optical signal level detected.
