Connecting Fiber-Optic Cables To Sfp Ports - Enterasys D2G124-12 Hardware Installation Manual

Connecting to the Network
If storing or shipping an SFP which has a fiber‐optic connector, insert its protective dust cover to
protect the ends of the fiber‐optic fibers from dust or contamination.

Connecting Fiber-Optic Cables to SFP Ports

Before connecting cables to SFP ports, you must install the appropriate transceiver as described in
Installing an Optional SFP on page 2‐29. This section describes how to connect a 1‐Gigabit fiber‐
optic segment from the network or other devices to an MT‐RJ or LC port connector.
Each fiber‐optic link consists of two fiber‐optic strands within the cable for Transmit (TX) and
Receive (RX). The transmit strand from a device port connects to the receive port of a fiber‐optic
1‐Gigabit Ethernet device at the other end of the segment. The receive strand of the applicable LC
or MT‐RJ port connects to the transmit port of the fiber‐optic 1‐Gigabit Ethernet device.
Refer to Figure
To connect an LC or MT‐RJ cable connector to an SFP port connector:
1. Remove the protective covers (not shown) from the uplink port SFP and from the connectors
on each end of the cable.
2. Insert the cable connector into the
2-32 Installation
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 fiber-port 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 losextremos de los cables de
fibra óptica se ensucian, utilice aire comprimido paralimpiarlos. También puede limpiarlos con un
estropajo embebido en alcohol isopropílico.

Note: Leave the protective covers in place when the connectors are not in use to prevent
contamination.
