FCN-2000L-2 Fiber to the Building Indoor CATV Cable TV Node CATV
FCN-2000L-2 Optical Fiber Receiver for Indoor CATV Cable TV
FEATURES:
- Compact indoor FTTB design
- Working at 1550nm/1310nm optical wavelength
- 45~862MHz RF bandwidth
- High performance and low power consumption GaAs Technology
- RF AGC maintaining a stable RF output
- Dual RF outputs
OVERVIEW:
FCN-2000L-2 optical receiver converts the optical signal from the head end into CATV RF. FCN-2000L-2 is designed for indoor Fiber to the Building (FTTB) application. The compact housing includes 100~240V AC power supply, Optical receiving unit with microprocessor controlled RF AGC, RF amplifier and distribution board. FCN-2000L-2 can be installed inside the building without any extra line amplifier. The RF level of each of the two RF output can be 42dBmV (at 0dB attenuation pad). The stable RF level enables the field installation and maintenance easier.
