62.5/125 µm or 50/125 µm (core/cladding)
Gigabit-SX
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.
9/125 µm (core/cladding) diameter, 1310 nm,
Gigabit-LX
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.
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
information.
9/125 µm (core/cladding) diameter, 1550 nm,
Gigabit-LH
low metal content, single mode fiber-optic
cables, complying with the ITU-T G.652 and
ISO/IEC 793-2 Type B1 standards.
Note: Between the transmit and receive ends of the cable, at least 5dB of attenuation is
required for a reliable connection. This is equivalent to 20Km of the fiber-optic cable. For
distances less than 20Km, you must add attenuators to bring the total attenuation to at least
5dB. Most cable vendors carry attenuators.
