Product Details

1.25G 20KM LC 1310/1550nm Single mode single fiber BIDI SFP Module

Description

The 1.25G BIDI SFP supports dual data-rate of 1250MGbps and from 10km to 20km transmission distance with SMF.

The 1.25G BIDI SFP consists of two sections: The transmitter section incorporates a FP laser. the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA).

1.25G BIDI SFP satisfy class I laser safety requirements. The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault indicates that degradation of the laser. Loss of signal (LOS) output indicates the loss of an input optical signal of receiver.

The standard serial ID information compatible with SFP MSA describes the transceiver’s capabilities, standard interfaces, manufacturer and other information. The host equipment can access this information via the 2-wire serial bus. For more information, please refer to SFP Multi-Source Agreement (MSA)
