HANDLING PRECAUTION FOR PD/APD MODULE
The NEC PD/APD module has heat shrink tubing to protect the ferrule edge (*1) and the junction between the ferrule and the module
body (*2). In order to avoid breaking the fiber and/or optical coupling degradation, NEC recommends the following handling
precautions:
1. Do not make the fiber bend radius less than 30 mm (*3).
2. Do not bend the fiber within the 18 mm section from the module body (*4).
3. Do not stress the ferrule with a lateral force exceeding 500 g (*5).
