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.
