The transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The LS-SM312G-40C SFP transceivers are high performance, cost effective modules supporting data rate of 2. 5Gbps and 40km transmission distance with SMF. You can narrow down the list of manufacturers based on their location and capabilities, browse their product catalogs, view their profiles, and send inquiries. Whether you are creating a 100-Gbps or 400-Gbps, small form-factor pluggable (SFP) module, SFP+ transceiver, XFP module, CFP, X2/XENPAK module.
