The FWR-1090MG building optical receiver is a low-power optical receiving product designed to adapt the optical passive (PON) access network fiber to the building (FTTB). This device adopts highly sensitive optical phototube, low noise gallium arsenide amplifier chip in preposition and gallium arsenide push-pull amplifier circuit in last stage which provides maximum output level over 2×102dBuV. This machine is also equipped with high-precision switching power supply, AGC automatic output level control, optical receiving power, RF output signal attenuation and equalization digital display. Due to the superior performance of the main components and the carefully designed circuit coordination, the performance index and superior reliability of the whole device are guaranteed.
◆ PIN optical receiving power, -1dBm receiving sensitivity, AGC receiving range: +2 ~ -7dBm, output stable level: 2×102 dBuv or 1×104 dBuv.
◆ Wide bandwidth type: 47 ~ 1000MHz working bandwidth.
◆ The setting function keys composed of up and down can achieve the adjustment of equalization and output level. When pressing the setting button of equalization, the light is on and LCD displays the output signal equalization, you can adjust it according to the design requirements. While pressing the set button of RF output attenuation, the light is on and LCD displays output level attenuation value, you can adjust the attenuation value according to the design requirements.
◆ This device is usually installed in the chassis, the chassis shell must be grounded, the grounding resistance should be less than 4Ω. The power supply shell of the feeder must also be grounded, the grounding resistance is the same as above, and the cable, power supply shell and the device shell should be connected at the same position, the chassis must be grounded before it is powered by city network voltage.
