Notes:
1. Voltages on V
CC
must be from the same power supply (they are connected together internally).
2. Signal Detect is a logic signal that indicates the presence or absence of an input optical signal. A logic-high, V
OH
, on Signal Detect
indicates presence of an input optical signal. A logic-low, V
OL
, on Signal Detect indicates an absence of input optical signal.
3. All GNDs are connected together internally and to the internal shield.
4. DATA, DATA, SD, SD are open-emitter output circuits.
5. On metal-port modules, these pins are redefined as “Port Connection.”
