... JGB-12SYAA1 JGB-12LYAA1 Gigabit Ethernet GBIC Resetting a Fault (Tx_Fault) Resetting the Tx_Fault output by toggling the Tx_Disable input permits the GBIC to attempt to power on the laser following a fault condition. Continuous resetting and repowering of the laser under a hard fault condition could cause a series of optical pulses with sufficient energy to violate laser safety standards. To alleviate this possibility, the GBIC will turn off the laser and lock the Tx_Fault line high if a second fault is detected within the laser powering on ...

... Use an optical power meter to check the optical power level. If the average optical power is within specification (> -17 dBm for short- wave devices), then the GBIC might be faulty. GBIC.1250 03/06/02 JGB-12SYAA1 JGB-12LYAA1 Gigabit Ethernet GBIC Page ...
