OFW-400 Intermediate
Frequency(IF) Fiber Optic Interfacilify Link(IFL) System
Description
The OFW-400 Intermediate Frequency (IF) Fiber Optic Interfacility
Link (IFL) System is the principle hardware for long-haul transmission
of IF signals in the frequency range of 5 MHz to 300 MHz over singlemode
fiber optic cable. The standard transmitter and receiver configuration
provides transmission distances up to 50 km. An optional extended-range
configuration can be specified that increases the link range to
80 km. The system’s optical conversion process is functionally
independent of the IF carrier’s data modulation format. The
links have low noise and high dynamic range characteristics, a wide
operating temperature range and provide turnkey installation.
The system provides status monitoring through the use of an onboard
processor that communicates with a host computer over a RS-232 I/O
interface. The I/O parameters include laser bias current, optical
receive power, internal temperature and alarm monitoring. In addition,
an optional Low Noise Amplifier (LNA) or integrated Bias-T for remote
LNA powering may be specified. Also, the system may be specified
with an extended frequency range of 5 MHz to 500 MHz. Finally, the
OFW-400 when specified with the 75 ohm input/output impedance option
provides a high-performance, cost-effective solution for CATV Return
Path signal distribution in Hybrid Fiber/Coax Networks.
