Product Details

1.25G 850nm SFP 550M MM SX GLC-SX-MM SFP-GIG-SX AT-SPSX J4858D J4858C JD118B

Description

The SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and

550m transmission distance with MMF. The transceiver consists of three sections: a VCSEL 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 transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
