A simple power loss test can inform us about the condition of the fibers. 
This test consists of measuring with an optical power meter the output 
power at one end of the tested fiber as at the other end a fiber source is 
connected. If the values are in dBm, the difference between the input 
power and the output power gives the power attenuation of the fiber (in 
dB). 

 

In case the above equipment is not available, a simple visual test may be 
performed to locate and reject badly damaged fibers. Place near one end of 
the fiber a light source and block alternatively the termination, you must 
observe the light coming out of the other end. (This procedure does not 
guarantee that a fiber is acceptable) 

A standard 62.5μm fiber optic cable is characterised by an 
attenuation factor of around 3 to 5dB/km. Then a loss value of more 
than 3dB for runs up to 200m can indicate a suspect fiber.   

Note 

The fiber optic cables must be installed by a specialist. 

HANDLE THE FIBERS VERY CAREFULLY. 

 

 

Type   

 

For connecting the Transceiver to the peripheral equipment a 2 pairs STP 
cable is required (one pair for the transmission and one for the reception). 
This cable must be a straight one when the peripheral has an MDI-X 10 
Base T interface and a Gross one otherwise. 

 

Connectors  
The cable should be terminated with an RJ-45 connector on the 
Transceiver end.

 

 

 

 

Type:  For connecting the Transceiver to the peripheral equipment a 2 
pairs STP cable is required (one pair for the transmission and the other for 
the reception) for each E1 or T1 connection.  

 

Connectors A special connector is provided by MRV to connect the 
twisted pair cables to the TS.
