Data rate upgrade of existing CWDM/DWDM networks to 10 Gbps
services running through the same system.
Transponders perform the 3R functionality in order to maintain the
signal’s best quality. For laser safety requirements, all transponders are
equipped with the Automatic Laser Shutdown (ALS) feature, which
reduces the optical power of the transmitters automatically in case
of a broken link. The ALS feature is implemented on both ports of the
transponders (DWDM side and Terminal equipment side).
The loop-back as well as the Remote Laser Shutdown functions assist
in troubleshooting the network and providing a cost effective way of
pinpointing a problem.
The Link Integrity Notification function allows the terminal equipment
to detect the link failure in the path between the two terminal
equipment units regardless of the location of the failure. The link failure
is propagated throughout the network until it reaches the terminal
equipment, by disabling the transmission immediately upon failure
detection at the opposite port of the transponder.
The TM-DXFP transponders provide power monitoring on the DWDM
port in addition to Digital Diagnostics supplied from the XFP port. This
function provides a dB value of transmitting and receiving optical signal
at each transponder, giving the network manager an additional tool for
analyzing the quality of the fiber optic network.
Overview
The TM-DXFP transponder is part of the LambdaDriver
®
product line
and can be hosted by the LD400, LD800 and LD1600 chassis. The
transponders are single slot modules that interface between the CWDM
or DWDM multiplexers and 10 Gbps terminal equipment. These modules
provide transparent light paths at ITU-T grid DWDM wavelength, which
carry 10 Gbps traffic.
The TM-DXFP modules support OC-192/STM64 (9.95 Gbps) and 10 GbE
(10.3Gbps) protocols.
Field upgrade of existing CWDM or DWDM networks to 10 Gbps speeds
is easy: just add this module to a LambdaDriver chassis at the appropriate
wavelength.
The terminal equipment interface possesses an XFP (10 Gbps Small Form
Factor Pluggable) receptacle, thus providing the highest flexibility in the
terminal equipment interface selection. Using XFP transceivers enables
the customer to easily change the type of optical interface according
to the different needs of the terminal equipment. XFP transceivers are
pluggable, and can easily be reused at different locations for different
applications, thus maximizing the return on investment in optics and
equipment, and reducing the on-hand parts inventory.
Transponders are operated completely independently of the other parts
of the system and can be hot swapped without having to interrupt other
