24 Product description
local system and the Remote IPE site is approximately 6 miles. With a
singe-mode fiber-optic link, the maximum distance is approximately 15
miles. The actual distance depends on the quality of the fiber-optic cable
and cable splices.
The Fiber Remote Multi-IPE Interface provides ST-type optical connectors,
which are compatible with multi-mode fibers at 62.5um/125 um
(micrometer) or with the single-mode fibers at 8.3 um/125 um.
A redundant fiber-optic link is optionally available on the Fiber Remote
Multi-IPE Interface to provide greater transmission reliability between
the local system and the Remote IPE sites. The Fiber Remote Multi-IPE
Interface automatically transfers the communication to the redundant link
when the primary link fails. When the primary link problem is corrected,
it becomes the spare link and the transmission does not switch to it until
the currently active link fails.
The Fiber Remote Multi-IPE Interface optical interface performs the
following functions:
•
•
•
Superloop interface
The Fiber Remote Multi-IPE Interface is equipped with four superloop
network connectors. These are 37-pin D Shell connectors that are used to
directly connect the Fiber Remote Multi-IPE Interface to the local network
I/O panel or to the Remote IPE I/O panel 24-pin Centronics connectors.
The Fiber Remote Multi-IPE Interface can accommodate from one to four
superloops depending on the type selected. For types of Fiber Remote
Multi-IPE Interface, refer to

Each superloop supports 120 timeslots for voice and data. Eight
additional timeslots are used to carry out-of-band signaling and messaging
information across the fiber-optic link.

provides a single or a redundant dedicated optical link to connect the
Remote IPE to the local system
monitors fiber-optic link integrity and transmission quality and provides
automatic link switching from the failed primary link to the redundant
link, if equipped
provides local and remote loopback testing of the fiber-optic link by
using a fiber-optic cable to loop the fiber-optic interface at either end
of the fiber-optic link
