Fiber Optic Requirements 

3.7.1 

Authorized Optic Cables 

The following specified optic cables are authorized for use with the MRU product: 

•

 

Composite plenum tether assemblies 

•

 

Fiber: LC APC, 2 – 24 fibers   

•

 

Cu:     16 AWG, 14 AWG, 12 AWG; 2 – 12 Conductors 

•

 

Armored, non-armored     

3.7.2 

Fiber Optic Rules   

•

 

Use only LC APC connectors 

•

 

UniCam connectors can be used for field termination 

•

 

Use only fusion splice for connecting two fibers 

•

 

Use minimum splicing/connectors to achieve minimum losses on the fibers (< 0.5 dB) 

•

 

Use precaution while installing, bending, or connecting fiber optic cables: 

•

 

Fiber optic cable is sensitive to excessive pulling, bending and crushing forces. Consult the cable specification sheet for 
the cable you are installing.   

•

 

Do not bend cable more sharply than the minimum recommended bend radius.   

•

 

Do not apply more pulling force to the cable than specified.   

•

 

Do not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission characteristics of 
the cable. The cable may have to be replaced. 

•

 

Use an optical power meter and light source for checking the fiber optic cables 

•

 

Make sure the environment is clean while connecting/splicing fiber optic cables 

•

 

All fiber optic connectors should be cleaned prior to connecting to the system 

•

 

Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are 

terminated. 

•

 

Pay special attention while connecting the LC APC connectors – ensure that you hear a “click”, indicating a secure 

connection 

•

 

Never look directly into the end of a fiber that may be carrying laser light. Laser light can be invisible and can damage your 

eyes. 

3.8

 

Grounding Requirement   

Verify that the equipment has been well grounded (refer to the grounding lug on the bottom front panel of the MRU chassis. This 
includes antennas and all cables connected to the system. Ensure lightning protection for the antennas is properly grounded. 
See sections 

 

4.2.3 for MRU grounding connection. 

3.9

 

Manual Handling   

During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation 
personnel and the equipment.
