How to install the fiber transceiver

1. first see if the indicator light and the twisted port port indicator light of the fiber transceiver or the light module is on?

A. If the light port (FX) indicator of the transceiver is not bright, please determine whether the optical fiber link is cross -linking? One end of the optical fiber jump line is in parallel; the other end is a cross -way connection.

B. For example, the light port (FX) indicator of the A transceiver is on, and the light port (FX) indicator of the B transceiver is not bright, then the failure is on the A transceiver: one may be: A transceiver (TX) light sending The mouth is bad, because the optical port (RX) of the B transceiver cannot receive the light signal; the other possibility is: the optical fiber link in the light sender (TX) of the A transceiver (TX) is a problem with the light sending port (optical cable or light jumper may broken).

C. The twisted line (TP) indicator is not bright, please determine whether the twisted line connection is wrong or the connection is error? Please use the pass test instrument to detect (however The road was turned on).

D. Some transceivers have two RJ45 ports: (ToHub) indicates that the connection cable of the connection switch is the pass line; (Tonode) means that the connection line of the connection switch is the cross line.

E. Some hairlines have MPR switches on the side: indicate that the connection cable of the connection switch is the direct line method; the DTE switch: The connection cable of the connection switch is the cross line method.

2. Is the optical cable and optical fiber jumping line broken?

A. Optical cable disconnection test: Lightrobia, sunlight, light, light emitting body against the light cable joint or puppet clipper; whether there is visible light on the other end? If there is visible light, the optical cable is not broken.

B. Fiber connection interruption test: Use laser flashlight, sunlight, etc. to illuminate the light of the fiber jump line; whether there is visible light on the other end? If there is visible light, it indicates that the fiber jump line is not broken.

3. Is there any error in the half/full duplex?

Some transceivers are FDX switches: indicate full dual -workers; HDX switch: indicate half dual -workers.

4. Use light power meter meter detection

Optical fiber transceiver or optical module in normal circumstances: multi-mode: -10DB --18DB; single-mode 20 kilometers: -8db --15DB; 60 kilometers of single mode: -5DB-1 12DB between: -5DB-1 12DB ; If the luminous power of the fiber transceiver is between: -30DB-45DB, then you can determine that there is a problem with this transceiver.
