Important: Use a protective cap to protect the end of the fiber while the fiber is being 

fished (or handled in general). 
To pull the optical cable to the module, follow these steps. 

1. 

Insert the Fiber Fish tool through the slot located just above the bottom of the 

chassis. 

2. 

At the rear of the chassis, locate the appropriate optical cable. 

3. 

Insert the optical cable into notched area of the Fiber Fish tool as shown. 

 

4. 

At the front of the chassis, pull the Fiber Fish tool (with cable attached) to the 

front of the chassis. 

5. 

Disengage the optical cable from the Fiber Fish tool and attach to the 

appropriate connector on desired module. See Cable Connection Procedure. 

Cleaning fiber-optic connectors can help prevent interconnect problems and 

therefore aid system performance. When optical connectors are disconnected and 

reconnected, the fiber surface can become dirty or scratched. The goal of cleaning the 

fiber optic connectors is to remove all dust and contaminants without leaving any 

residue.  

The following equipment is required to clean the ends of fiber-optic connectors. 
• 

Optical-grade (91%) isopropyl alcohol 

• 

Lint-free wipes 

• 

Compressed air (also called “canned air”)
