Fiber retractor remote machine

Optical fiber retractor remote machine - wireless intercom system

Optical fiber retractor mainly consists of optical near-end machine, optical fiber and optical far-end machine (covering unit). Optical near-end machines and optical remote machines both include radio frequency units (RF units) and optical units. The wireless signal

After coupling from the base station, into the light proximal machine, through the electro-optic switch, electrical signals into light signals, from the proximal light input to the optical fiber, light through the optical fiber transmission to the remote machine, the remote machine to put the light signal into electrical signal, into the RF unit of amplification, signal after amplification to the transmitting antenna, covering the target area. Working principle of the uplink - The signal transmitted by the sample terminal device is transmitted to the optical remote machine through the receiving antenna, then to the near-end machine and back to the base station.

Main features of optical fiber retractor:

1. Adopt high isolation and low insertion loss duplex filter to eliminate upstream and downstream crosstalk.

2. The system has low noise, good linearity, ideal communication effect, and no interference to base station and other wireless equipment.

3. A perfect monitoring system, can monitor and set the parameters of multiple systems, while supporting remote wireless monitoring, powerful.

4. Optical fibers are used to connect the near and far ends, which provides long transmission distance and low loss, and supports multi-drag networking, which is convenient and flexible.

5. The module is intelligent and highly integrated, easy to maintain, upgrade and install.
