GLC-SX-MM-OEM Specifications, R01 full 16 bit value (0 – 65535) with LSB equal to 2 μA, yielding a total range of 0 to 131mA. Accuracy is better than ±10% over specified operating temperature and voltage. Transceiver TX output power, internally measured, represented as a 16 bit unsigned integer with the power defined as the full 16 bit value (0 – 65535) with LSB equal to 0.1 μW. Data is assumed to be based on measurement of laser monitor photodiode current.

GLC-SX-MM-OEM Specifications, R01 The TX_DISABLE signal is high (TTL logic “1”) to turn off the laser output. The laser will turn on within 1ms when TX_DISABLE is low (TTL logic “0”). TX_FAULT When the TX_FAULT signal is high, output indicates a laser fault of some kind. Low indicates normal operation. Receiver Section The receiver utilizes a PIN detector integrated with a trans-impedance preamplifier in an OSA.
