Specifications

Fiber-Optic

■ Gigabit-SX LC connectors on the Gigabit-SX mini-GBIC (used on the 10-

Port Mini-GBIC Interface Module) transmit at 850 nm wavelength, and are

compatible with the IEEE 802.3z Gigabit-SX standard. These connectors

accepts the low metal content, multimode fiber-optic cables for Gigabit-

SX described in Table 6.

■ Gigabit-LX LC connectors on the Gigabit-LX mini-GBIC (used on the 10-

Port Mini-GBIC Interface Module) transmit at 1310 nm wavelength, and

are compatible with the IEEE 802.3z Gigabit-LX standard. These connec-

tors accept the low metal content, single-mode or multimode fiber-optic

cables for Gigabit-LX described in Table 6.

■ Gigabit-LH LC connectors on the Gigabit-LHX mini-GBIC (used on the

10-Port Mini-GBIC Interface Module) transmit at 1550 nm wavelength, and

accept the low metal content, single-mode fiber-optic cables for Gigabit-

LH described in Table 6.

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 page 33 for more information.

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.
