The SIL-01-25-B131-10XD is a 1Gbps Singlemode BiDi (Bi Directional) SFP module.
SilverNet BiDi SFP modules transmit and receive signals with different wavelengths, they should be purchased as pairs so you can connect the two BiDi SFPs which have the opposite wavelength together. So if you use a TX1310/RX1550nm BiDi SFP at one end, then we must use a TX1550/RX1310nm (SIL-01-25-B155-10XD) BiDi SFP on the other end.
The SIL-01-25-B131-10XD modules are capable of data rates up to 1Gbps over a distance of up to 10km. They are compliant with the SFP MSA specification and operate from 0~+70°C
