Engineering The Fiber-Optic Link - Nortel 1000 Manual

four modules. Each IPE module requires one Fiber Peripheral Controller
card located in the IPE module and a corresponding Fiber Superloop
Network card located in a local network card slot.
Note:
to two IPE modules. However, in a system with the Fiber Remote
IPE configuration, a Fiber Superloop Network card supports only one
Remote IPE module. This is due to the dedicated fiber-optic link
configuration between the Fiber Superloop Network card and the Fiber
Peripheral Controller card. Since fiber-optic links are dedicated, they
cannot be shared between two different IPE modules at the remote site.
Wall-mounted Fiber Remote IPE
The wall-mounted Fiber Remote IPE consists of NT1P70 main and
NTAK12 expansion cabinets. The main cabinet supports the Fiber
Peripheral Controller card and up to 10 IPE cards or 160 ports. If more
ports are required, an expansion cabinet can be installed adjacent to the
main cabinet.
These two cabinets are linked with an inter-cabinet cable that plugs into P1
50-pin connectors located at the bottom left-hand corner of each cabinet.
This cable extends six peripheral bus DS-30X loops to the first six IPE
card slots in the expansion cabinet. One Fiber Peripheral Controller card
located in the main cabinet supports cards in both main and expansion
cabinets as long as the expansion cabinet contains no more than 6 IPE
cards installed in the first six IPE card slots.
Engineering the fiber-optic link
A fiber-optic link can be constructed using single-mode or multi-mode
fiber-optic cables. The type of fibers selected depends on various factors:
•
distance between the local system and the Fiber Remote IPE site
•
possible existence of a fiber-optic link you wish to use for this
application
•
cost and availability
When engineering a fiber-optic link, consult the component manufacturer's
data sheets to determine whether the cable, connectors, and other
components meet the transmission characteristics and the signal loss plan
for the transmission distance required for the specific Fiber Remote IPE
application.
Fiber-optic bandwidth
When using a single-mode fiber, the optical link transmission distance is
strictly loss-limited and not dispersion-limited. When using multi-mode
fiber, the transmission distance is loss- and dispersion-limited. Appropriate
