Quick Information

  • Brand Name: BEST
  • Place of Origin: China
  • Model Number : 830-06B

Description

Summary:

The unit is used to extend the distance of transmitting the analog or digital analog signal of the 1310nm or 1550nm system by relay transmitting or second time transmitting at the head-end, after receiving 1310nm or 1550nm signal.

The unit can realize mixing the local channel signal while relay transmitting 1310nm downstream optical signal, with two independent RF output ports.

 

Features:

1 With both optical receiving and transmitting function to offer a solution of direct-relay signal without house for CATV 1310nm optical transmission system.

2 Realize mixing with the local channel

3 With ≥ 98dBuv output level to drive around 200 users

4 With DFB coaxial laser

5 Laser indicator; with alarm LED indicator against unusual condition

6 High-quality and high-performance switch power supply

7 Water-proof compact shell

Testing conditions:

Standard optic fiber and standard optical receiver composes the testing links, under the following testing conditions: 84 PAL-D analog channels in the bandwidth of 750 MHz; -1dBm receiving; with certain loss, to test C/N, C/CSO, and C/CTB.

Installation and Operation Items:

The fiber enters from” Fiber Input”, and connects the “Input” and “Output” one by one. Don’t make the wrong order with the connecting, or it will cause permanent damage to the laser.

1. The intensity of the input RF signal is connected with directly with the receiving power, along with which the intensity will increase as the receiving goes high. It happens that the RF signal intermodulates with the receiving signal when the RF input level is too low.  And the intensity of the input RF should be modulated according to the present project conditions. (the range of the input RF is 80-96dBuv)

2. There are four pcs hex screw on the shell, which must be fastened tight and even after finish modulating.

3. The shell and the power socket must be well earthed to prevent the vulnerable parts from, like the laser, from being damaged, and the people from being hurt. ( The earth impedance should be less than 4 ohms)

Warranty and Repairing Items:

1. One year warranty and life long repairing when the warranty is expired.

2. All the products must go through 24-hour high temperature aging after strict tests to guarantee the high stability of the optical devices and amplifier module. And the unstable devices will be replaced with new ones and then tested again. If the unit is broken by improper usage, like the power supply, not good grounding, other human reasons and the force majuere like lighting, we will not be responsible for the cost.
