9.2 Connecting Fiber
Caution
The OSR-CWDM is designed for maximum power of +5 dBm per channel and a maximum com
-
posite power of +23dBm.
Caution
Fiber-optic connectors are easily contaminated or damaged. The connection to the OSR-
CWDM is a physical contact type of connection and dirty or damaged connectors may impair the
instruments capabilities at minimum and at worst result in the need to return the OSR-CWDM
to the factory for expensive repairs. Prior to making any connection to the unit, ensure that all
proper cleaning procedures have been followed.
Use UPC Finish Connectors Only!
It is suggested that a test cable be used between the fiber under test and the OSR-CWDM. This reference
fiber should be approximately on meter in length and have minimal loss. The reference cable should be only be
removed from the unit when necessary. Limiting removal and termination of connectors to the unit will extend the
live span of the connector eliminating down time and costly repairs. Only UPC connectors are to be connected
to the OSR-CWDM.
