GBIC Description

The GBIC is a hot-swappable input/output device that plugs into a Gigabit Ethernet port, linking the

port with the ﬁber-optic network. A GBIC is shown in Figure 1.

Figure 1 Gigabit Interface Converter

Table 1 is a list of the available GBICs.

WS-G5484 The WS-G5484, 1000BaseSX operates on ordinary multi-mode ﬁber optic link spans of up to 550 m

in length (See Table 4).

WS-G5486 The WS-G5486, 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX

standard. However, their higher optical quality allows them to reach 10 km over single-mode ﬁber

(SMF) versus the 5 km speciﬁed in the standard.

WS-G5487 The WS-G5487, 1000BaseZX operates on ordinary single mode ﬁber optic link spans of up to 70

km in length. Link spans of up to 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 per unit

length, and less dispersion).

The WS-G5487 must be coupled to single mode ﬁber optic cable, which is the type of cable typically

used in long haul telecommunications applications. The WS-G5487 will not operate correctly when

coupled to multi-mode ﬁber, and it is not intended to be used in application environments (e.g.

building backbones, horizontal cabling) where multi-mode ﬁber is frequently used.

The WS-G5487 is intended to be used as a Physical Medium Dependent (PMD) component for

Gigabit Ethernet interfaces, as found on various switch and router products. It will operate at a

signaling rate of 1250 MBaud, transmitting and receiving 8B/10B encoded data.

Safety Recommendations

When shorter distances 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:

•A 10 dB in-line optical attenuator should be inserted between the ﬁber optic cable plant and the

receiving port on the WS-G5487 GBIC at each end of the link whenever the ﬁber optic cable span

is less than 25 km.

•A 5 dB in-line optical attenuator should be inserted between the ﬁber optic cable plant and the

receiving port on the WS-G5487 GBIC at each end of the link whenever the ﬁber optic cable span

is equal to or greater than 25 km, and less than 50 km.

Note The maximum number of installed 1000BASE-ZX GBICs is limited in each Catalyst chassis.

These limits are necessary in order to fall within the emission speciﬁcations for these products.

Table 2 is a list of the GBIC limits for the different Catalyst systems.

Safety Recommendations

This section describes the warning symbol used in this document and GBIC handling

recommendations.

Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before

you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with

standard practices for preventing accidents. To see translations of the warnings that appear in this publication,

refer to the appendix “Translated Safety Warnings” in the Catalyst 4000 or 5000 Series Installation Guide.

Speciﬁcations

GBIC speciﬁcations are listed in Table 3.

Port Cabling Speciﬁcations

Table 4 provides cabling speciﬁcations for the GBICs that you install in the Gigabit Ethernet port.

Note that all GBIC ports have SC-type connectors, and the minimum cable distance for all GBICs

listed (multimode ﬁber [MMF] and SMF) is 6.5 feet (2 m).

1000BaseLX/LH GBICs, and a short link distance (10’s of meters) can cause transceiver saturation resulting in an elevated bit error

rate (BER).

In addition, when using the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord

between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is

required for link distances greater than 984 ft (300 m).

Handling a GBIC

Note The mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required to comply

with IEEE standards. The IEEE found that link distances could not be met with certain types of

ﬁber-optic cable cores. The solution is to launch light from the laser at a precise offset from the

center, which is accomplished by using the mode-conditioning patch cord. At the output of the patch

cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BaseLX.

Note The WS-G5487 1000Base-ZX GBIC provides 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 this ﬁgure. The optical loss

measurement must be performed with a 1550 nm light source.

Handling a GBIC

GBIC handling guidelines follow:

•GBICs are static sensitive. To prevent electrostatic discharge (ESD) damage, follow your normal

board and component handling procedures.

•GBICs are dust sensitive. When storing a GBIC or when a ﬁber-optic cable is not plugged in,

always keep plugs in the GBIC optical bores.

•The most common source of contaminants in the optical bores is debris picked up on the ferrules

of the optical connectors. Use an alcohol swab or Kim-Wipe to clean the ferrules of the optical

connector.

Installing a GBIC

Gigabit Ethernet switching modules can be shipped with or without GBICs installed.

Note GBICs are hot-swappable in Gigabit Ethernet modules.

Perform the following steps to install a GBIC.

Step 1 Remove the GBIC from its protective packaging.

Step 2 Check the part number to verify that the GBIC is the correct type for your network (see

the “GBIC Description” section on page 2).

Step 3 Grip the sides of the GBIC with your thumb and foreﬁnger and insert the GBIC into the

slot on the front panel of the Gigabit Ethernet switching module, as shown in Figure 2.

Note GBICs are keyed to prevent incorrect insertion.

Step 4 Slide the GBIC through the ﬂap covering the opening into the slot until you hear a click.

The click indicates the GBIC is locked into the slot.

Warning Class 1 laser product

Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode ﬁber-optic

modules when no cable is connected. Avoid exposure and do not stare into open apertures.

Step 5 When you are ready to attach the network interface ﬁber-optic cable, remove the plug

from the GBIC and save the plug for future use.

Removing a GBIC

If you are removing a defective GBIC, perform these steps.

Step 1 Disconnect the network ﬁber cable from the GBIC SC connector.

Step 2 Release the GBIC from the slot by simultaneously squeezing the two plastic tabs (one on

each side of the GBIC).

Step 3 Slide the GBIC out of the Gigabit Ethernet module slot. A ﬂap drops down to protect the

Gigabit Ethernet module connector.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device,

pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection

against harmful interference when the equipment is operated in a commercial environment. This

equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in

accordance with the instruction manual, may cause harmful interference to radio communications.

Operation of this equipment in a residential area is likely to cause harmful interference, in which

case users will be required to correct the interference at their own expense.

You can determine whether your equipment is causing interference by turning it off. If the

interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices.

If the equipment causes interference to radio or television reception, try to correct the interference

by using one or more of the following measures:

•Turn the television or radio antenna until the interference stops.

•Move the equipment to one side or the other of the television or radio.

•Move the equipment farther away from the television or radio.

•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That

is, make certain the equipment and the television or radio are on circuits controlled by different

circuit breakers or fuses.)

Modiﬁcations to this product not authorized by Cisco Systems could void the FCC approval and

negate your authority to operate the product.

Class 1 Laser Compliance

This product has been tested and found to comply with the limits for Class 1 laser for IEC825,

EN60825, and 21CFR1040 speciﬁcations.
