Description
Transmitter ground
Laser failure indication. High level indicates “laser failure”. Externally
pulled up
Transmitter disable, High signal/open disables TX laser output. Low
level enables TX output, internally pulled up.
Module definition 2, SDA, Data line for I2C bus. Externally pulled up
Module definition 1, SCL, Clock for I2C bus. Externally pulled up
Module definition 0, Module present. Ground inside module.
No connection.
Receiver loss of signal indication. Low signal indicates optical signal is
present at RX input. Should be Externally pulled up.
