Description

The ESFP transceivers are high performance, cost effective modules supporting multi-rate of  155Mbps~2.67Gbps and 80km transmission distance with SMF.

      The transceiver consists of three sections: a DFB laser transmitter, a APD 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.

Notes:

1. The optical power is launched into SMF.

2. PECL input, internally AC-coupled and terminated.

3. Measured with a PRBS 2²³-1 test pattern @2488Mbps, BER ≤1×10^-12.

4. Internally AC-coupled.
