The minimum bend radius for optical cables is 3 cm (1.2 in).
For the 50-micron cable operating at 2.125 Gbit/s the recommended maximum distance is 300 meters
and at 1.0625 Gbit/s, the recommended maximum distance is 500 meters. For the 62.5-micron cable
operating at 2.125 Gbit/s the recommended maximum distance is 150 meters and at 1.0625 Gbit/s, the
recommended maximum distance is 300 meters. All of these maximum lengths assume no more than
two connections/splices in the link.
CX300, CX500, and CX700 storage systems require optical cable
between servers, switches, and SPs. The cabling between SPE or
DPE2 and DAE2 enclosures is copper.
EMC standard multimode optical configurations use 50 micron cable.
EMC does not recommend mixing 62.5 micron and 50 micron optical
cable in the same link. In certain situations, however, you can add a
50 micron adapter cable to the end of an already installed 62.5 micron
cable plant. Contact your customer service representative for details.
Generally, you should minimize the number of cable connections,
since each connection degrades the signal slightly and shortens the
maximum distance the signal can carry.
Fibre Channel Data Cable Types and Sizes
Typical Use
In a single cabinet, connects the SPE or DPE2 to a DAE2.
In the same cabinet, connects a DAE2 to a DAE2.
Cabinet to cabinet, connects the SPE or DPE2 to a DAE2.
Cabinet to cabinet, connects a DAE2 to a DAE2.
In a single cabinet, connects the SPE or DPE2 to switches.
In a room, connects the SPE or DPE2 to switches or HBAs.
(Adapter must support optical cable.)
LC-SC cables are used on the EMC 1-Gbit Fibre Channel
products. You can use LC-SC cables to connect an HBA to a
switch, a switch to the SPE, or an HBA to the SPE.
