MITSUBISHI (OPTICAL DEVICES)

MF-2500FXE Series

2.5Gbps SFP TRANSCEIVER MODULE

5. Electrical characteristics

All parameters are specified over the operating case temperature.

Measurement conditions are at 2.48832Gbps +/-20ppm, NRZ PN2

The DATA input/output signal interface is AC-coupled internally.

TX_DISABLE input signal level is LVTTL compatible. (With internally pull-up 4.7k to 10k

Ω)

TX_FAULT and LOS (Loss Of Signal) output are Open-Collector/drain, and the levels indicated assuming 4.7k

to 10k ohm pull up resistor to Host_Vcc is present.
