certain period of time when active pass is resumed to normal condition);
When the equipment is started, it is preferential to have both local
end and remote end operating with the A optical interface.
ALS (Automatic Laser Shutdown/Automatic Laser Reduction)
function: When a fiber disconnection in this optical pass is detected, the
average output power at the optical transmitting end is reduced by more
than 20dB, and it resumes to normal status when optical fiber is
recovered.
The
optical interface
applies an optical transmitting/receiving
integrated module of impact structure. It features high-power
transmission, high-sensitivity receiving and independent transmission
and receiving. The new version supports hot plugging/swap of optical
interface. In the case that one optical interface runs into trouble, the fault
optical interface board can be drawn out online and replaced with a new
one.
Network management Unit
is designed to control all settings on the
control panel and to realize communications between multiplexer and
computer. The unit can send commands (such as alarm-off, remote
bypass loop-back and so on) to nodes through computer. Users can
directly query and set the status of a pair of devices with Hyper Terminal
software
via
RS232
crosswire.
NM-ETH
interface
(10/100M
auto-negotiating, to be configured) can be directly connected with a
computer via a crosswire or with a HUB via a straight-through wire to fulfill
management. It can realize ALS (Automatic Laser Shutdown/Automatic
Laser Reduction) to prevent personnel from fiber injury. The user can
select network management functions according to its actual
requirements.
