Product Description

Optical Switch 2X1
(FWSW-2X1)

 

1.Introduction
FWSW-2x1 optical path selector (commonly known as an optical switch) is mainly used as the protection mechanism of optical fiber networking in optical networks. In addition to low loss, it provides a good switching design in terms of an optical switch, making the switching speed of the optical switch lower than 10ms. At the same time, considering whether the optical signal RF signal monitoring and automatic switching and alarm. The front panel LCD section will provide real-time QAS monitoring parameters and alarm information, as well as some functions and parameters that can be set. In addition, the front panel LED indicator light provides a real-time alarm display.
2.Features
It supports the real-time monitoring of the optical power of main and standby devices. When the optical power falls to the set value, it can automatically switch to the backup channel through network management control and trigger an alarm. Switching thresholds can be set for the actual received optical power of two links respectively.
 Under the condition that both main and standby optical signals are normal, the device supports the automatic, manual, or forced switching function of the optical circuit.
Rf monitoring shall be carried out in the main and standby optical signals. If a certain rf signal is lost, it will automatically switch to the normal channel.
The excellent technical performance of ultra-short switching time: fast response time, switching time less than 10ms, keeping the electro-optical circuit off.
With the radiofrequency detection function, when the main road has an optical signal but no radio frequency signal, the network management can timely alarm.
International and domestic standard SNMP Over IP Ethernet interface, remote network management; The reference threshold of switching action and the switch of the optical route should be set in the network management system. Monitoring parameters include optical routing status, input and output signal power, etc.

6.Application of network management System
The machine with functions of network management, light path selector network IP address set of steps to set up the IP address, just pick up the signals to RJ45 interface in the local area network (Ethernet), and then from any front-end ports connected to the main server in the local area network (LAN), the network management master server (PC) is installed on the standard of HFC network equipment management system application software, when you run the network management system can real-time monitoring the machine running status.


7 The notes about the optical connection
7. 1) before you connect them, carefully cleaning all the fiber optic connectors and connectors
Cleaning Guide:
7.1.1) Fiber Optic jumper
Removal of the dust cap of fiber optic connector, pay attention to confirm the optical connector is an APC surface;
The tips of cleaning fiber optic connector are to use a dedicated and dry cloth without velveteen (the company 5Kimwipes ®'s fine cloth); In addition, preferably adopt a special microscope (at 100 times, 200 times) to check the cleanliness of fiber optic connector surface or blemish.
pay attention to maintaining the fiber optic connectors is clean;
fiber optic connectors (flange) is clean;
you can use a dedicated compressed gas to clean the surface of the fiber optic connector;
you can remove the dust which is less than 0.2 microns, better without residue;
hold the tank of compressed air from the connector about 6 inches, alignment flange, and press the nozzle switch shortly times, so you can clean the connector completely;
if there is no dedicated compressed air, the 2.5 mm cotton swab for cleaning can also be used to clean the optical transmitter connectors, or remove the flange and clean the other side of the optical fiber jumper connector directly ;
Note: When handling fiber optic connectors must be very careful to avoid damage.
7.1.2) using the optical fiber jumper to connect the output of the optical transmitter to the optical power meter;
7.1.3) Using the optical power meter to check the output of the transmitter optical power is within normal limits;

8 Other notes
8.1) The machine should have a good grounding, grounding resistance should be smaller than 4Ω. According to international standards, the DC-48 line adopts the three-wire system, the midline is grounding wire.
8.2) The machine should be set up in an anti-hot, anti-cold, anti-wet environment, so as to avoid excessive temperature and humidity affect the useful life of the machine.
8.3) The machine adopts a high-performance, highly reliable switching power supply with constant voltage and over-current protection. In the right of switching power supply, there is 1A imported fuse that can be work at DC-48 electrical line.
8.4) To ensure the optical return loss ≥ of 45dB, this machine's optical connectors adopt SC / APC, other models (such as SC / PC) could not be picked. The connector should be installed to keep it clean. You should use ethanol and defatted cotton wool to wipe after the plug repeatedly.
8.5) Once the laser transmitter enters the work state because the light signal input(pump light input) is quite high light output for pump light, the eye cannot look directly at the light input from the back panel of the machine in order to avoid the laser beam burning the human eye retina.
