Arista Compatible DOM LC SFP Optical Module 850nm 550m 1000BASE-SX
1000BASE-SX SFP 850nm 550m DOM LC MMF Transceiver Module Compatible
Arista
Product Descriptions
Olinkcom's OLSP8512L-CDS5, 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.
