QFO-C

The Total Access 3000/3010 Quad Fiber Optic - Central Office (QFO-C) is designed
to carry up to four asynchronous DS1 circuits over single mode fiber at distances
beyond 24 km. Two units, one at the central office and the other at the customer's
premises, make up a complete system. The QFO-C occupies a single slot in the shelf,
but requires an odd/even pair of slots. The even slot must either be empty or filled
with a protect module. Its remote counterpart, the Quad Fiber Optic - Remote
(QFO-R), resides in its own remote two-slot shelf. The system can be provisioned for
single unit operation or take advantage of the Automatic Protection Switching (APS)
where one unit is online and a second is in hot-standby mode capable of carrying the
data load in the event of a line failure. See Figure 13.
