2.1.6. Gigabit Fiber SFP Interfaces
This product has two full-duplex 1000Base-LX single mode/ multi-mode
fiber interface, using hot-swappable SFP during the optical interface using LC
connectors. Optical interface to be used in pairs (TX and RX as a pair), TX
mouth to light the originator, the remote switch connected to another optical
interface of the light receiving end RX. RX ports for the light receiving end, to
connect with a remote switch with an optical interface light originator TX. The
use of two redundant 1000Base-LX optical interface fiber optic redundant ring
network can be formed in the system failure redundant ring switching time less
than 20ms, can effectively improve network reliability.
SFP optical module shown in the figure:
Hot-swappable SFP modules as follows:
Hot-plug procedure:
1.SFP during the observation of a finger end of the PCB.
2.The finger end into the SFP metal shielding cage, hear a click sound
indicates that the device has been inserted in place, then the SFP plug handle,
into the interface parallel to the normal position, you can use.
Hot drawing steps:
1.First unplug the SFP's plug handle perpendicular to the interface, this
time the device should be shielded with SPF cage mount hook disengaged.
2.Parallel to pull the SFP module.
