FEATURES
- F-TEL is a Fiber Optic Telephone Adapter, providing
direct, secure fiber optic connection between any telephone set and a PABX,
or between two telephone sets.
- F-TEL converts the electrical signals into optical
signals. Two in-line units are required to complete a fiber link: a PABX
unit (F-TEL/CO) for the PABX side and a Subscriber unit (F-TEL/SUB) for
the subscriber telephone set.
- As a backup to the AC supply, the PABX and
Subscriber units can be automatically powered by an on-board nickel-cadmiun
rechargeable battery. Another backup option is use of an external
low-voltage DC power supply or battery, that can be connected to a special
DC connector located on the rear panel of the unit.
- F-TEL can be operated in two typical
configurations:
- Telephone-to-PABX optical connection (Subscriber
to PABX)
- Telephone-to-telephone optical connection
(Subscriber to Subscriber).
- F-TEL is designed to operate with several grades
and sizes of fiber optic cable. Use of fiber optic cabling provides
immunity to electrical interference such as EMI and RFI.
- Three optical interfaces are available:
- 850 nm wavelength for multimode fibers
- 1300 nm wavelength for single mode fibers
- laser diode (1300 nm) for single mode over
extended range
- The laser diode has an internal temperature control
circuit to compensate for ambient temperature changes.
- LED status indicators are available on the front
panel of both units for indicating the system status.
- F-TEL is supplied as a standalone unit. Special
hardware for mounting the unit in a 19" rack can be ordered separately
