Connecting Fiber-Optic Cables to MT-RJ Ports

Warning: Do not use optical instruments to view laser output. The use of optical
instruments to view laser output increases eye hazard.
Advertencia: No utilizar instrumentos opticos para ver el laser. El uso de instrumentos
opticos para ver el laser incrementa el riesgo de perdida de la vision.
Warnhinweis: Benutzen sie keinesfalls optische Hilfmittel, um die Funktion des Lasers zu
überprüfen, es könnte ihr Augenlicht gefährden.
This section contains the procedures for connecting a 1000BASE‐SX multimode fiber‐optic
segment from the network or other devices to an MT‐RJ port connector in a Mini‐GBIC
(MGBIC‐MT01).
Each fiber‐optic link consists of two fiber‐optic strands within the cable:
• Transmit (TX)
• Receive (RX)
The transmit strand from a device port connects to the receive port of a fiber‐optic Gigabit
Ethernet device at the other end of the segment. The receive strand of the applicable
MT‐RJ port connects to the transmit port of the fiber‐optic Gigabit Ethernet device.
Enterasys Networks recommends labeling fiber‐optic cables to indicate receive and
transmit ends. Many cables are pre‐labeled, providing matching labels or tapes at both
ends of each strand of cable.
To connect an MT‐RJ cable to a fixed MT‐RJ connector of a Mini‐GBIC, refer to Figure
and proceed as follows:
1. Remove the protective covers (not shown) from the front panel MT‐RJ fiber‐optic port
(port 21 in this example) and from the connectors on each end of the cable.
Note: Leave the protective covers in place when the connectors are not in use to prevent
contamination.
