C/Ports at the desktop. The fiber optic cables from the output of the Transceiver can
be home runs to the individual C/Ports, or they can be patch cables that run to one or
more fiber patch panels.
The following requirements apply to the ClearCube Fiber Optic Extension System:
• Because the signals running between the Fiber Transceiver and the Fiber C/Port
are proprietary to the ClearCube architecture and NOT Internet Protocol (IP)
based, you cannot run the fiber cable through any networking equipment such as
switches and routers.
• The Fiber Optic Extension System only works with R4300 BackPacks and Blade
Switching BackPacks that are revision “E” or higher. The version can be
determined from the label on the side of the BackPack.
• The Fiber Optic Extension System only works with “straight-through” fiber optic
cable. This means that if light is transmitted down the fiber on the right-hand side
of the connector then at the other end of the cable, the light should come out on
the left-hand side of the connector.
• The total attenuation through all the connections between the Transceiver and the
Fiber C/Port must be 3 dB or less, including the cable itself.
• This system connects PC Blades at a maximum distance of 500 meters over a
pair of 62.5 micron multi-mode fibers.
Connect the Cables
For each user, a C/Port cable (max. length 10 m) is connected to the C/Port RJ-45
jack on the rear of the Cage and the other end of the cable is connected to the
corresponding RJ-45 jack on the Fiber Transceiver. A fiber cable terminated in a
MT-RJ plug, without pins, connects to the jack directly above the RJ-45 that is
connected to the Cage. The other end of this cable connects to the Fiber C/Port. Refer
to the connection diagram shown in Figure 33.
NOTE: Only one of each cable is shown in Figure 33. An actual installation would
have as many as 8 each C/Port and Ethernet cables per Cage, and as many
as 16 fiber cables per transceiver. See Figure 14 on page 38 for a more
detailed example.
