WARNING
Use protective caps to cover optical interfaces and optical connectors that are not in use.
After you remove a fiber jumper from an optical interface, use protective caps to cover the
optical interface and the fiber jumper connector.
Use an attenuator to prevent high optical power from damaging the optical receiver while
using a fiber jumper for the hardware loopback on an optical interface.
Before using an optical time domain reflectometer (OTDR), remove the fiber jumper

high optical power from damaging the optical receiver.
Do not insert or remove a module that is connected with a fiber.
