Note 1: TTL logic output, with internal 10K
pull-up resistor.
Optical Signal-Detected: High; Optical Signal Loss: Low
Note 2: LVPECL logic output, AC coupled internally. (See Recommended Interface Circuit)
Note 3: A positive level enable optical signal output under burst mode.
(See Timing Parameter Definition in Burst Mode Sequence)
Note 4: Compatible with LVPECL/CML input
(See Recommended Interface Circuit and Table 6 - Electrical Input/Output Coupling Mode)
Note 5: The mounting studs are provided for transceiver mechanical attachment to circuit board. They may also
provide an optional connection of the transceiver to the equipment chassis ground. The holes in the circuit
board must be tied to chassis ground. It is not recommended that the mounting studs be connected to
signal ground.
