1650nm Reflector LC/APC

The  fiber  brag  grating  reflector( FBG  Reflector)  is  a  low-cost  specific  band  reflector mounted on the optical network unit (ONU) side. It can reflect light pulses ( 1650 +/- 5 nm) from the OTDR on the fiber line terminal (OLT) side nearly 100%, while the working bands of the passive optical network (PON) are transmitted normally. The OTDR can determine whether the  fiber  line  is  normal  by  detecting  the  signal  reflected  by  the  fiber  grating reflector. When the reflected signal is lower than the normal value, the line loss is too large; when the reflection value is 0, the optical fiber line is broken 。Therefore, we can maintain the fiber line in time by the real-time monitoring of the fiber line.

Features   It supports comprehensive access to wireless fronthaul and other services, taking into account wireless fronthaul, private line, and home broadband services, and maximizes the value of fronthaul networks； Maximize optical fiber saving, one fiber can carry 9 channels of 4G & 5G fronthaul CPRI/eCPRI services； The local side is active and the remote end is passive, and WDM technology is used to extend the physical channel of pure transparent transmission, without delay and jitter introduction； It supports the monitoring function of the luminous power of each channel, which is easy to maintain and locate faults； It supports 1:1 protection at the optical layer, and the protection switching time is less than 20 ms, improving network reliability； The optical-layer protection function card can be selected according to the application scenario, and supports hot-swap and power-off/power-on-hold functions to ensure that the device does not affect service operation in the event of a power-off； It supports SNMP, Web and other graphical interface network management； Local end equipment active supports AC 220V, DC -48V power supply optional, and 1+1 power input protection； The installation method is flexible, the central office equipment supports rack-mounted installation and wall-mounted installation, and the remote equipment supports rack-mounted, pole-mounted and wall-mounted installation, which is easy to install and plug-and-play； The remote outdoor device meets the requirements of the IP67 standard and supports pole and wall mounting.  

Single-line dual-access - product features:   Easy to install and concealed： Single-line dual-access is a passive device with a low failure rate;  Small in size and can be used in a variety of ways fast installation in complex environment, strong concealment. Low insertion loss：The insertion loss of single-line dual-access devices is < 1.6dB, and the line margin is within the range after going online.
