Is the RX pin of the optical module an output pin

RX_LOS: It is an open collector/drain output, which should be pulled up with a 4. TTL logic HIGH when the receiver optical power is below the worst-case receiver sensitivity, logic LOW otherwise for normal operation. The transceiver's pin assignment is SFF-8679 compliant. Notes: GND is the symbol for signal and supply (power) common for the QSFP modules...
