Status LED

The front panel of the DS-1GLX module is composed of the following parts:

„1 standard SC gigabit long-wave optical interface

„1 LINK status indicator

„1 ACT status indicator

Of the above, the different states of LINK and ACT indicators show the port operating status. For details, refer to Table 2-9.

The fiber system is divided into two types by the optical transmission mode: Multi-mode fibers and single-mode fibers. The single-mode fiber is the fiber that transmits signal in a single mode at the given wavelength. Its core is about 4 ~ 10µm, which is quite small. The fiber features high transmission bandwidth and large transmission capacity.
