1250Mbps 1310nm Single-Mode 20km Industrial SFP Transceiver BT-SFP-IG20
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.
