A 1+1 protection architecture has one normal traffic signal, one
working transport entity, one protection transport entity, and a
permanent bridge.
At the source end, the normal traffic signal is permanently bridged to
both the working and the protection transport entities. At the sink end,
the normal traffic signal is selected from the better of the two transport
entities.
Due to the permanent bridging, the 1+1 protection architecture does
not allow an unprotected extra traffic signal to be provided.
The technology that is used for automatically shutting down the laser
to avoid the maintenance and operation risks when the fiber is pulled
out or the output power is over great.
The interface automatically chooses the rate and duplex mode
according to the result of negotiation. The auto-negotiation process is:
the interface adapts its rate and duplex mode to the highest
performance according to the peer interface, namely, both ends of the
link adopt the highest rate and duplex mode they both support after
auto-negotiation.
Small parts at both sides of the chassis, used to install the chassis into
the cabinet
Cabinet with width of 600 mm, depth of 600 mm, compliant with the
ETSI standard
It is a data transmission unit, composed of several parts, each of which
has different functions.
In a communication link, both parties can receive and send data
concurrently.
The cable to connect the device to ground, usually a yellow/green
coaxial cable. Connecting the ground cable properly is an important
guarantee to lightning protection, anti-electric shock, and anti-
interference.
