1.optical relay station
2.Outdoor water-proof shell
3.the certificates such as ISO9001,3C
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
