Connectrix v6.02 Planning Guide
Fiber-optic jumper cables are required to connect switch ports to
servers, devices, distribution panels, or other switches in a
multiswitch fabric.
All of the SFP optic modules on the ED-140M, ED-64M, and DS-xxM
utilitze LC connectors. These connectors are not interchangable with
SC connectors; however, adapter cables are available from EMC.
ISLs between an ED-1032 and an ED-xxM or DS-xxM would use an
SC/LC-style cable. ISLs between any two ED-xxM/DS-xxMs would
use LC/LC-style cables.
The standard SFP optic modules installed in the ED-xxM and
DS-xxM Fibre Channel switches are multimode optics. Both 50/125
and 62.5/125 multimode fiber will work with these multimode optic
modules; however, EMC recommends using 50/125 multimode fiber
for any new installations, due to its inherent distance advantage over
62.5/125 multimode fiber.
Types of cable are:
• Graded-index 50/125 multimode cable (50 micron core diameter,
125 micron cladding diameter). This type of cable provides a
transmission distance of 2 to 500 meters at 1 Gb/s or 2 to 300
meters at 2 Gb/s, and connects to shortwave ports that transmit
light at a wavelength of 850 nm. The cable typically has an orange
jacket.
• Graded-index 62.5/125 multimode cable (62.5 micron core
diameter, 125 micron cladding diameter). This type of cable
provides a transmission distance of 2 to 300 meters, and connects
to shortwave ports that transmit light at a wavelength of 850 nm.
The cable typically has an orange jacket.
• Dispersion-unshifted 9/125 single-mode cable (9 micron core
diameter, 125 micron cladding diameter). This type of cable
provides a transmission distance of 2 to 20 kilometers, and
connects to longwave ports that transmit light at a wavelength of
1310 nm. The cable typically has a yellow jacket.
