Connecting Fiber-Optic Cables to Mini-GBICs
Thissectionprovidestheprocedureforconnecting1‐GigabitEthernetfiber‐opticsegmentsfrom

ThefollowingproceduredescribeshowtoconnectanMT‐RJcable(Figure 4‐10)connectortoa
Mini‐GBICportconnector.ThisprocedurealsoappliestoanLCcableconnectorshownin
(Figure 4‐11).RefertoFigure 4‐10asanexampleandproceedasfollows:
1. Removetheprotectivecovers(notshown)fromtheMT‐RJfiber‐opticportontheMini‐GBIC
andfromtheconnectorsoneachendofthecable.
2. InserttheMT‐RJcableconnectorintotheMini‐GBICuntilitclicksintoplace.
.
Note: Leave the protective covers in place when the connectors are not in use to prevent
contamination.
Caution: Do not touch the ends of the fiber-optic strands, and do not let the ends come in contact
with dust, dirt, or other contaminants. Contamination of cable ends causes problems in data
transmissions. If the ends of the fiber-optic strands become contaminated, use a canned duster to
blow the surfaces clean. A cleaning swab saturated with optical-grade isopropyl alcohol may also
be used to clean the ends.
Precaución: No toque los extremos de los cables de fibra óptica y evite su contacto con el polvo,
la suciedad o con cualquier otro contaminante. Si los extremos de los cables se ensucian, es
posible que la transmisión de datos se vea afectada. Si nota que los extremos de los cables de
fibra óptica se ensucian, utilice aire comprimido para limpiarlos. También puede limpiarlos con un
estropajo embebido en alcohol isopropílico.
Note: To remove the MT-RJ cable connector, press on its release tab and pull it out of the
Mini-GBIC.
