GBIC Module and SFP Module Overview
SFP and GBIC Short Wavelength Modules
The 1000BASE-SX (short wavelength) GBIC module operates on standard multimode fiber-optic link
spans of up to 1804 feet (550 m). (See Table 6.)
The 100BASE-FX SFP module is a hot-swappable device that plugs into a Gigabit Ethernet SFP port. It
provides full-duplex 100-Mbps connectivity over multimode fiber (MMF) infrastructures. The
100BASE-FX SFP operates on ordinary MMF optical link spans of up to 1.2428 miles (2 km) in length.
SFP and GBIC Long Wavelength Modules
The 1000BASE-LX/LH (long wavelength/long haul) GBIC module interfaces fully comply with the
IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach
6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.
SFP and GBIC Extended Wavelength Modules
The 1000BASE-ZX (extended wavelength) GBIC module operates on ordinary single-mode fiber-optic
link spans of up to 43.5 miles (70 km). Link spans of up to 62.1 miles (100 km) are possible using
premium single-mode fiber or dispersion-shifted single-mode fiber (premium single-mode fiber has a
lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber
has both lower attenuation and less dispersion).
The 1000BASE-ZX GBIC module must be coupled to single-mode fiber-optic cable, which is the type
of cable typically used in long-haul telecommunications applications. The 1000BASE-ZX GBIC module
will not operate correctly when coupled to multimode fiber, and it is not intended to be used in
environments where multimode fiber is frequently used (for example, building backbones, or horizontal
cabling).
The 1000BASE-ZX GBIC module is intended to be used as a Physical Medium Dependent (PMD)
component for Gigabit Ethernet interfaces found on various switch and router products. It operates at a
signaling rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.
When shorter lengths of single-mode fiber are used, it may be necessary to insert an in-line optical
attenuator in the link to avoid overloading the receiver.
•Insert a 10-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port
on the 1000BASE-ZX GBIC module at each end of the link whenever the fiber-optic cable span is
less than 15.5 miles (25 km).

GBIC Module and SFP Module Overview
•Insert a 5-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port on
the 1000BASE-ZX GBIC module at each end of the link whenever the fiber-optic cable span is equal
to or greater than 15.5 miles (25 km) but less than 31 miles (50 km).
GBIC Module and SFP Module Cabling and Connection Equipment
The GBIC module port is a 1000-Mbps optical interface in the form of an SC-type duplex port (see
Figure 1) that supports IEEE 802.3z interfaces compliant with the 1000BASE-X standard.
Table 6 provides cabling specifications for the GBIC modules and SFP modules that you install in
Gigabit Ethernet devices. Note that all GBIC module ports have SC-type connectors and all SFP ports
have LC-type connectors.
The minimum cable distance for the WS-G5484 or GLC-SX-MM and WS-G5486 or GLC-LH-SM
(multimode fiber [MMF] and single-mode fiber [SMF]) is 6.5 feet (2 m), and the minimum link distance
for the WS-G5487 or GLC-ZX-SM is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of
the link. Without attenuators, the minimum link distance for the WS-G5487 or GLC-ZX-SM is 24.9
miles (40 km).

2. A mode-conditioning patch cord is required.
When using the WS-G5486 or GLC-LH-SM with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC module
or SFP module and the MMF cable on both the transmit and the receive ends of the link when link distances are greater than 984 ft (300 m).
We do not recommend using the WS-G5486 or GLC-LH-SM and MMF with no patch cord for very short link distance (tens of meters). The result could
be an elevated bit error rate (BER).

Cisco 1000BASE-T SFP Modules
Note The 1000BASE-ZX GBIC module and SFP modules provide an optical power budget of 21.5 dB. You
should measure your cable plant with an optical loss test set to verify that the optical loss of the cable
plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement
must be performed with a 1550-nm light source.
Cisco 1000BASE-T SFP Modules
The 1000BASE-T (GLC-T) SFP module is compliant with IEEE 802.3:2000 and plugs into a standard
Gigabit Ethernet SFP module port. It operates on standard Category 5 wiring and has an RJ-45
connector.
See your router installation and configuration guide to determine which routers support the GLC-T SFP
module.
