Overview

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 20km transmission distance with SMF.
The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

    Notes:
    1. The optical power is launched into SMF.
    2. PECL input, internally AC-coupled and terminated.
    3. Measured with a PRBS 27-1 test pattern @1250Mbps, BER =1x10-12.
    4. Internally AC-coupled.
