connection to 10Base-T, 100Base-T or 1000Base-T local area networks (LANs) as per IEEE
std 802.3. The receptacle labeled OPTICAL PORT is for the installation of an SFP module
and allows connection to 1000Base-SX, 1000Base-LX or 1000Base-CX LANs as per IEEE
std 802.3.
The front panel has not been designed to support mechanical stress. All cabling in the
rack where the mounting frame is located should be properly supported so that the front
panel does not provide mechanical support.
3.6.1. Connecting to the electrical ports
Connections to the electrical ports are made with RJ-45 connectors. The cabling used
should be UTP Category 5 or better (Cat 5e o Cat 6) in order to guarantee proper
operation at 1Gbit/s.
3.6.2. Connecting to the optical port
The SFP fiber optic module must be inserted into its housing as described previously
before interconnection. Modules for fiber optic transmission using the 1000Base-LX,
1000Base-SX as per IEEE std 802.3 or modules for transmission via cabling using
1000Base-CX as per IEEE std 802.3 can be installed.
If SFP modules using 1000Base-SX as per IEEE std 802.3 are used then the fiber optic
cabling used must be multimode. Such modules are appropriate for links of up to a
few hundred meters. If SFP modules using 1000Base-LX as per IEEE std 802.3 are used
then multimode fiber optic cabling can be used for short distances (up to 500 meters)
however monomode fiber optic cabling must be used for links that extend up to five
kilometers.
Optical connections are performed in the SFP/SFP+ module, which is equipped with
LC/PC connectors. Connectors using single-mode fiber optics are usually blue.
Connectors for multimode fiber optics are usually gray.
All fiber optic cables have a minimum curvature radius that must be obeyed (consult
the specification of the cabling used) and should be run with enough strain relief to
absorb small, unintended pulling or mechanical stress.
Before connecting the fiber optic cabling, remove the protective endcap. Any unused
fiber optics must be covered by their endcaps.
Fiber optic connections are sensitive to dust and dirt. Any dust or dirt particles trapped
in the optical pathway act as attenuators of unknown value and in the worst case can
render the signal unusable. Care must be taken to ensure the cleanliness of and not to
dirty the connectors during insertion and removal of the fiber optic cables.
In systems designed for transmission over 1000Base-CX cabling as per IEEE std 802.3
the SFP modules and the cable are joined together and the only way to remove them
is to extract the module from its receptacle.
