			Description
		
			The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of
		
			1.25Gbps/1.0625Gbps and 20km transmission distance with SMF.
		
			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 transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further
		
			information, please refer to SFP MSA.
