Outdoor Rainproof HFC Terminal Optical Devices With 2 Output Ports , TFR7800Vc
Overview
TFR7800Vc optical receiver is outdoor rainproof one-way optical receiver, can be used in the CATV network, digital network and telecom network.The optical receiver mainly aims at meeting the requirements of cable TV network transformation design adopting high-quality, high-performance and high-efficiency ptical odetector. RF input with low noise GaAs amplifier chip and output amplifier stage is made of high-quality GaAs amplifier module with high reliability, low power consumption, low noise, high output level and extremely excellent cost performance.
TFR7800Vc ‘s receiving optical power range is + 2 ~ -9 DBM. AGC range is + 2 ~-8 DBM,optical output level reached 108 dbuv. When optical receiving power is - 6 DBM, C/N is larger than 46 db and MER is more than 35 db.
Users can choose 60 v or 220 v power supply, converted to DC+ 24 v, + 5 v by the high-performance conversion circuit to supply power for the device inside the receiver.This product experiencing the strict reliability life test, the average trouble-free working hours MTBF is more than 100 thousand hours.It is fully compliant with national and SCTE HMS network management standards and IEC NM standard and can provide remote management and monitoring of working status to improve the reliability of network.
Features
- Perfect surge suppression circuit improves the resistance to lightning further improving the reliability
- Input stage with low noise GaAs amplifier chip, output stage CATV use special GaAs double power amplifier greatly improving the C/N and nonlinear distortion characteristics
- Nixie tube displaying receive optical power makes a convenient test
- with AGC function.receiving within +2 ~ -8 DBM, each RFPUT level IS as high as 108 dbuv and RF output level change will not more than + / - 0.5 dB
- When connecting with TFT1000M, C/N > 51.0 dB, CSO > 61 DBC, CTB > 65 DBC
- Experiencing reliability test, MTBF is more than 100thousand hours
