FTTH Micro Optical Receiver ZHR10M3
Performance characteristics
◆High quality plastic shell, through hole design on both sides, with good heat dissipation.
◆RF channel full GaAs low noise amplifier circuit. The digital signal satisfies -15dBm reception and the analog signal satisfies-10dBm reception.
◆With optical input AGC function
◆Anti-high frequency surge protection GaAs amplifier tube.
◆Low-power design, high-efficiency switching power supply ensures high reliability and high stability of the power supply. The overall power consumption is only 2W, with optical detection circuit.
◆SC/APC & SC/PC&FC/APC&FC/PC optical connectors, custom male or fe-male RF connector.
◆Multi-stage lightning protection device (TVS transient suppression diode), lightning protection system is tight, ensuring the safe operation of the equipment
Applications
The ZHR18 series optical terminal is a home-use optical receiver for FTTH (Fiber to the Home) network optical fiber access terminals to enable analog or digital signals to enter the home. The machine uses low-power photodetectors, GaAs and optical AGC technology to meet the fiber-to-the-home CATV reception needs. Many functional products are slightly different in application.

Note 1: 59 PAL-D analog television channel signals are allocated in 550 MHz and full-band digital modulation signals are transmitted in 550 MHz-862 MHz every 2 MHz under the specified link loss. The digital modulation signal level is
10 dB lower than the analog modulation signal level, and the optical receiver input optical power is -1 dBm. The test results will be different according to the different amplification modules of the optical receiver configuration.
