Fibre Optic Port Specification (Cont..)
Fibre Optic Care
Fibre optic transmission medium is usually made of Glass. In addition, the diameter of the
fibre can be as low as 9um. In comparison, the diameter of an average piece of Human hair is
40 um.
Therefore, a small piece of dust or contaminate located on the end of a patch cable
could easily disrupt communications.
The fibre optic transceivers and associated patch cables must be treated with great care.
Therefore, the following rules should be adhered to during any commissioning work and fibre
optic installation.
•
Dust caps must be replaced immediately after removal of patch cable from
transceiver or patch box. Failure to comply could result in damage to transceivers or
patch cables.
•
Keep hands clean when touching fibre optic cable.
•
Patch cables should be cleaned with IPA and dried with a lint-free cloth before
installation.
•
Once patch cables have been installed dust will not ingress the transceiver
NOTE: Permanent damage to both fibre patch cords and fiber optic transceiver
components may be the result of just a small invisible piece of dust!
