Did the salesman fool customer? Don’t be afraid, we’ll explain details to you.
First, components of optical fiber signal repeater
The optical fiber repeater is mainly composed of five parts: near-end optical fiber machine, optical fiber jumper, remote optical fiber machine, feeder jumper and receiving and transmitting antenna.
Second,the working principle of optical fiber repeater After the wireless signal is coupled from the base station, it enters the near-end optical fiber repeater. The near-end optical fiber repeater converts the RF signal into an optical signal, and then transmits it to the remote optical fiber repeater through the optical fiber jumper, the remote optical fiber repeater restores the optical signal to the RF signal, and then enters the RF unit for amplification, and the signal is sent to the transmitting antenna after amplification, covering the target area.
Third, main features of optical fiber repeater
1. Adopt duplex filter with high isolation and low insertion loss to eliminate upstream and downstream crosstalk.
2. The system has low noise, good linearity, ideal communication effect, and no interference to base stations and other wireless equipment.
3. Has a perfect monitoring system, can monitor and set multiple system parameters, while supporting remote wireless monitoring, powerful.
4. Optical fibers are used to connect the local and remote ends, which provides long transmission distance and small loss. In addition, a drag-and-multiple network is supported for convenience and flexibility.
5. The module is intelligent and highly integrated, which is easy to maintain, upgrade and install.
Last, the difference between fiber repeater and wireless signal repeater
Because the transmission of optical fiber repeater is non-feeder, there is basically no loss for ultra-long distance signal transmission, and it is more suitable for ultra-long distance signal coverage projects. The wireless repeater uses feeder transmission, there will be loss in the process of transportation signal, and the loss increases with the increase of distance, and the transportation distance can not be compared with the optical fiber repeater.
However, the price of optical fiber repeater is also higher than that of wireless repeater, which can be chosen according to the location and budget.
