Fiber-Optic Cables
The following table indicates the characteristics of the fiber-optic cables you
should use when connecting to the Gigabit-SX and Gigabit-LX mini-GBICs use
in your Series 5300XL Switches. Use cables fitted with LC connectors.
Note 1000Base-T Cable Requirements. The Category 5 networking cables that
work for 100Base-TX connections should also work for 1000Base-T, but for
the most robust connections you should use cabling that complies with the
Category 5E specifications, as described in Addendum 5 to the TIA-568-A
standard (ANSI/TIA/EIA-568-A-5).
Because of the increased speed provided by 1000Base-T (Gigabit-T), network
cable quality is more important than for either 10Base-T or 100Base-TX.
Cabling plants being used to carry 1000Base-T networking must comply with
the IEEE 802.3ab standards. In particular, the cabling must pass tests for
Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT).
Additionally, unlike the cables for 100Base-TX, the 1000Base-T cables must
pass tests for Equal-Level Far-End Crosstalk (ELFEXT), Multiple Disturber
ELFEXT, and Return Loss.
When testing your cabling, be sure to include the patch cables that connect
the switch and other end devices to the patch panels on your site. The patch
cables are frequently overlooked when testing cable and they must also
comply with the cabling standards.
Port Type Cable Specifications Maximum Length
Gigabit-SX 62.5/125 mm or 50/125 mm (core/cladding)
diameter, graded-index, low metal content,
multimode fiber-optic cables, complying with
the ITU-T G.651 and ISO/IEC 793-2 Type A1b or
A1a respectively.
• 62.5 mm cable:
– 160 MHz*km = 220 meters
– 200 MHz*km = 275 meters
• 50 mm cable:
– 400 MHz*km = 500 meters
– 500 MHz*km = 550 meters
Gigabit-LX 9/125 mm (core/cladding) diameter, 1310 nm, low
metal content, single mode fiber-optic cables,
complying with the ITU-T G.652 and ISO/IEC
793-2 Type B1 standards.
OR
the multimode fiber-optic cables listed for
Gigabit-SX.
• single-mode cable: 10 kilometers
• multimode cable: 550 meters
Note: To use multimode cables for Gigabit-LX, a mode conditioning patch cord may be needed
— see “Mode Conditioning Patch Cord for Gigabit-LX” on page 22 for more information.
