Connecting Fiber-Optic Cables to LC 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 describes how to connect
• a 1000BASE‐SX multimode fiber‐optic segment from the network or other devices to
an LC port connector of a Mini‐GBIC (MGBIC‐LC01 or MGBIC‐LC03), or
• a 1000BASE‐LX single‐mode fiber‐optic segment from the network or other devices to
an LC port connector of a Mini‐GBIC (MGBIC‐LC09).
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 LC
port connects to the transmit port of the fiber‐optic Gigabit Ethernet device.
Enterasys 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 LC cable connector to a fixed LC connector of a Mini‐GBIC, refer to
Figure 3‐21 and proceed as follows:
