1RF Fiber Optic to RF Converter AGC fiber optic cable tv receiver Output port Active ftth nodes for CATV FTTH
1. Product Description
OR18 Series Optical receiver is a home-based optical receiver for FTTH (fiber to the home) network optical fiber access terminal, in order to achieve analog or digital signal. The machine uses low-power optical detectors, GaAs and AGC technology to meet the needs of FTTH CATV reception. A variety of functional products in the application, slightly different.
OR18A and OR18B pay attention to product economy practicability,
among them OR18B has AGC control function, bring economical
application to the user, the minimum that the digital signal
receives is -15dBm; OR18C and OR18D pay attention to the product
high performance index, possess AGC function, digital signal
receive 0 ~ -18dBm.
2.Advantages
♦ High-quality plastic shell, through-hole design on both sides,
good heat dissipation;
♦ RF channel full GaAs low noise amplifier. Digital signal minimum
to meet -18dBm receiver, analog signal minimum to meet -10dBm receiver;
♦ With AGC function (AGC range can be customized);
♦ Anti-high-frequency surge protection device GaAs amplifier tube;
♦ Low-power design, the use of high-efficiency switching power
supply to ensure that the power of high reliability and high
stability.
Overall power consumption is only 2W, with optical detection
circuit;
♦ SC / APC & SC / PC & FC / APC & FC / PC optical
connector options, male or female RF interface;
♦ Multi-level lightning protection device (TVS transient
suppression diode), lightning protection system,
to ensure the safe operation of equipment

Note 1: Under the specified link loss, 59 PAL-D analog TV channel signals are configured in 550MHz and all band digital modulated signals
are transmitted every 2MHz in 550MHz-862MHz. The digitally modulated signal level is 10dB lower than the analog modulated signal level
and the optical receiver input optical power is -1dBm. The test results will be different according to the optical receiver configuration of the different amplification module.
