・
To polish connectors:
For SFP+ optical transceiver for multimode
: PC polishing is recommended.
For SFP+ optical transceiver for singlemode : UPC polishing is recommended.
Note:
APC polishing is not supported.
・
Extension distance varies depending on attenuation of the fiber, connector and other contact portions
・
Make sure not to exceed the allowable tension and bend radius of fiber optic cable or the performance of
the product and the life of the fiber optic cable may be affected
・
Plug the dust caps to both faces of the fiber optic cable when connecting the fiber optic cable and when not
in use
・
Before inserting a fiber optic cable, make sure there is no damage or dirt on the end-face of the optical
connector. Clean up it or NJR-W01UHD may not operate correctly
