1000BASE-EX SFP 1310nm 40km Transceiver

Model:UF-SFP-1G-40, UF-SFP-1G-L40

•Data rate:1.25G
•Wavelength (nm):1310
•Media Type:SMF

The SFP transceivers are high performance, cost effective modules supporting 1.25Gbps data-rate and 40km transmission distance with SMF.

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.
