LambdaDriver 400 & 800
ML46430, Rev. 07
October 2004
This function enables a pair of GM2 modules
to carry up to two Gigabit Ethernet channels over a
fiberoptic cable. Gigabit Ethernet channels can be carried inband
can be installed in the LDx00 in slots 1 to 16.
Using just two LDx00s, sixteen pairs of GM2 modules
can carry 32 Gigabit Ethernet channels
inband
(using CWDM or DWDM) over
a
single
physical fiberoptic cable.
Major benefits in the use of GM2 modules
include:
−
Extended operating range
−
Concurrent carriage of data of other protocols.
−
Immediate, easy, and quick deployment
−
Cabling bulk reduction by a factor of as much as 32
−
Lower cost
−
Advantages afforded by fiberoptic cabling, such as greater reliability, increased security,
and added safety
−
Pluggable add-on scalability and growth
The GM2 WDM and ACCESS interfaces can be fitted with any vendor SFP. This endows the
GM2 module with flexible connectivity to terminal equipment and minimizes cost of investment on
upgrades and deviations since to change any one or more of the interface properties, only the
SFP, and not the whole GM2 module, needs to be replaced.
