OMX shelf (not required with OMX + Fiber Manager 4CH)

(NTN449ZW)
The OMX shelf fits into a bay with four OPTera Metro 3500 shelves. OMX
technology combines various wavelengths over a single optical fiber using a
passive optical coupler.
An optical patch panel in the OMX shelf connects the optical fibers from the
OC-192 or OC-48 DWDM circuit packs to OMX modules.
The OMX modules multiplex optical signals together at the OC-192 or OC-48
line rate. Each OMX module has 12 faceplate interconnects. For details of the
OMX shelf, see

Equipping rules

One OMX shelf can be mounted in an eight foot bay equipped with four
OPTera Metro 3500 shelves. One OMX shelf supports two OMX modules, one
working and one protection. See
temperature ranges.
Planning and Ordering Guide—Part 1 of 2 NTRN10AN
Each OMX + Fiber Manager 4CH is a 1U high external drawer that
contains optical filters, a small patch panel with bulkhead connectors, and
fiber management components. The drawers can be mounted anywhere in
a rack. Nortel Networks recommends that you install the trays directly
beneath the shelf.
Each OMX + Fiber Manager 4CH uses bulkhead connectors and patch
cords to connect circuit packs.
Note: The OPTera Metro OMX does not support OC-48 DWDM 1535.04
nm, OC-48 DWDM 1555.75 nm, OC-48 DWDM 1596.34 nm or OC-48
DWDM 1578.69 nm wavelengths.
