BT-SFP-IG20 transceiver is compliant with SFP MSA, high performance at low cost, which supports operating data-rate up to 1250Mbps.
The transmitter section and receiver section work independently in the transceiver. The receiver section contains an InGaAs Pin photodiode, a transmipedance amplifier and a post amplifier (with working data rate up to 1250 Mbps), functionally transmit received optical power into steady electrical data. The transmitter section contains a 1310nm FP laser diode with back-face monitor and a laser driver with APC function, transmitting input electrical data to steady optical output signal.
The product is compliant with the SFP MSA such as the LC optical interface receptacle, 3.3V supply voltage, TTL signal detect logic.
