Functions Description:
The laser is driven by a LD driver IC which converts differential input LVPECL (3.3V) or PECL (5V) logic
signals into an analog laser driving current.
MGB-243X complies with Module Definition 4. It features an EEPROM that contains the detailed product

GBIC Transceiver
MGB-243S
HG Genuine
information stored for retrieval by host equipment. This information is accessed via the 2-wire serial CMOS
EEPROM protocol of ATMEL AT24C01A.
TX_Fault
When sensing an improper power level in the laser driver, the GBIC set this signal high and turns off the Laser.
TX_FAULT can be reset with the TX_DISABLE line. The signal is in TTL level.
TX_Disable
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").
Receive Loss (RX_LOS)
The RX_LOS is high (logic "1") when there is no incoming light from the companion transceiver. This signal
is normally used by the system for the diagnostic purpose. The signal is operated in TTL level.
