Fiber Optic Cables
Gigabit-SX
(on Gigabit-SX-LC
mini-GBIC)
Multimode fiber-optic cables designed for
Gigabit Ethernet: 62.5/125 μm or 50/125 μm
(core/cladding) diameter, 850 nm, low metal
content, graded-index cables, fitted with LC
connectors. The cables must comply with the
ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a
standards.
• 62.5 μm cable:
– 160 MHz/km = 220 meters
– 200 MHz/km = 275 meters
•50 μm cable:
– 400 MHz/km = 500 meters
– 500 MHz/km = 550 meters
Gigabit-LX
(on Gigabit-LX-LC
mini-GBIC)
Single-mode fiber-optic cables designed for
Gigabit Ethernet: 9/125 μm (core/cladding)
diameter, 1310 nm, low metal content cables,
fitted with LC connectors. The cables must
comply with the ITU-T G.652 and ISO/IEC 793-2
Type B1 standards.
The multimode cables specified for the Gigabit-
SX mini-GBIC may also be used, but a mode-
conditioning patch cord may be needed — see
“Mode Conditioning Patch Cord for Gigabit-LX”
on page B-3 for more information.
• single-mode cable = 5 kilometers
• multimode cable = 550 meters
Gigabit-LH
(on Gigabit-LH-LC
mini-GBIC)
Single-mode fiber-optic cables designed for
Gigabit Ethernet and fitted with LC connectors.
• single-mode cable = 70 kilometers
10-GbE SR Multimode fiber-optic cable designed for
Gigabit Ethernet: 62.5/125 μm (core/cladding)
diameter or 50/125 μm, 850 nm, low metal
content, complying with the ITU-T G.652 and
ISO/IEC 793-2 Type B1 standards.
■ 62.5 μm cable:
• 160 Mhz/km = 2-26 meters
• 200 Mhz/km = 2-33 meters
■ 50 μm cable:
• 400 Mhz/km = 2-66 meters
• 500 Mhz/km = 2-82 meters
• 2000 Mhz/km = 2-300 meters
10-GbE LR 9/125 μm (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.
single-mode cable: 2-10 kilometers
10-GbE ER 9/125 μm (core/cladding) diameter, 1550 nm,
low metal content, single mode fiber-optic
cables, complying with the ITU-T G.652 and
ISO/IEC 793-2 Type B1 standards.
single-mode cable: 2-30 kilometers (40
kilometers, on an engineered fiber optic link
that meets standards in the specification).
Note: Conditioning patch cord cables are not supported on 10-GbE speeds.
