Caution: Only qualified technicians should install this equipment. Place all printed circuit boards on an antistatic mat until you are ready to install them. If you do not have an antistatic mat, wear a discharge leash to free yourself of static before touching any of the printed circuit boards, or free yourself of static by touching a grounded metal object before handling a printed circuit board. Product Safety Meets requirements of: CSA 22.2 No. 950-M95/UL1950, 3rd ed.
Advertencia: Los equipos de fibra óptica pueden emitir radiaciones de láser o infrarrojas que pueden dañar los ojos. No mire nunca en el interior de una fibra óptica ni de un puerto de conexión. Suponga siempre que los cables de fibra óptica están conectados a una fuente luminosa. Avvertenza: Le apparecchiature a fibre ottiche emettono raggi laser o infrarossi che possono risultare dannosi per gli occhi. Non guardare mai direttamente le fibre ottiche o le porte di collegamento.
Figure 1 GBIC extraction tabs and extractor handle GBIC model with extractor tabs GBIC model with extractor handle 9702FA GBIC labeling The Nortel Networks label on a typical GBIC (Figure 2) contains a Nortel Networks serial number, a bar code, a manufacturer’s code, an interface type, and a part number.
Note: When you contact a Nortel Networks service representative for troubleshooting purposes, you must have the following information available: • Nortel Networks serial number • Manufacturer’s code • Interface type • GBIC part number GBIC model list Table 1 lists and describes the Nortel Networks GBIC models.
Handling, safety, and environmental guidelines Before installing your GBIC, read the following handling, safety, and environmental guidelines: • GBICs are static sensitive. To prevent damage from electrostatic discharge (ESD), follow your normal board and component handling procedures. • GBICs are dust sensitive. When you store a GBIC, or when you disconnect it from a fiber optic cable, always keep the dust cover over the GBIC’s optical bores.
2 Verify that the GBIC is the correct model for your network configuration (Table 1 on page 4). 3 Remove the dust cover from the GBIC’s optical bores. 4 Grasp the GBIC between your thumb and forefinger. 5 Insert the GBIC into the slot on the front panel of the Gigabit Ethernet switching module (Figure 3) . Figure 3 Inserting the GBIC into the switching module Note: GBICs are keyed to prevent incorrect insertion. Removing a GBIC This section lists the steps for removing a GBIC.
2 Depending on your GBIC model, either grasp the extraction tabs (Figure 1) located on either side of the GBIC with your thumb and forefinger, or lift the extractor handle (Figure 1) attached to the GBIC. 3 Slide the GBIC out of the Gigabit Ethernet module slot. 4 If the GBIC does not slide easily from the module slot, use a gentle side-to-side rocking motion while firmly pulling the GBIC from the slot. 5 Dispose of the GBIC according to all national laws and regulations.
Standards, connectors, cabling, and distance This section describes GBIC standards, connectors, cabling, and distance; and provides specifications for the following GBICs: • “1000BASE-SX,” next • “1000BASE-LX” on page 9 • “1000BASE-XD” on page 11 • “1000BASE-ZX” on page 13 GBIC ports for both multimode and single-mode fiber have SC-type connectors and a minimum cable distance of 6.5 feet (2 m).
Table 3 1000BASE-SX specifications (continued) Type Cabling Specifications 62.5 µm MMF optic cable 50 µm MMF optic cable Distance 902 ft. (275 m) using 62.5 µm MMF optic cable 1804 ft.
Table 4 describes standards, connectors, cabling, and distance for the Model 1000BASE-LX GBIC. Table 4 1000BASE-LX specifications Type Standards Specifications Conformity to the following standards: 802.3z, 1000BASE-LX Connectors Cabling Duplex SC fiber optic connector 62.5 µm MMF optic cable 50 µm MMF optic cable 10 µm SMF optic cable Distance 1804 ft. (550 m) using 62.5 µm MMF optic cable 1804 ft. (550 m) using 50 µm MMF optic cable 16405 ft.
Note: When multimode fiber is used in long-distance applications, external, removable, mode-conditioning patch cords may be required to prevent differential mode delay (DMD). You can order mode conditioning patch cords through Nortel Networks: • SC-SC Mode-Conditioning Patch Cord 62.5/125 (part number AA0018035) • SC-SC Mode-Conditioning Patch Cord 50/125 (part number AA0018036) 1000BASE-XD The Model 1000BASE-XD GBIC provides Gigabit Ethernet connectivity using SC duplex single-mode fiber connectors.
Table 5 1000BASE-XD GBIC specifications (continued) Type Specifications Connectors Duplex SC single-mode fiber optic connector Cabling Single-mode fiber optic cable Distance Up to 50 km using single-mode fiber cable, depending on the quality of the fiber Optical budget 17 dB Laser Transmitter Characteristics Wavelength 1550 ± 10 nm Maximum spectral width 0.2 nm Maximum launch power 0 dBm or 1.0 mW Minimum launch power into fiber -5 dBm or 0.
1000BASE-ZX The Model 1000BASE-ZX GBIC provides Gigabit Ethernet connectivity using SC duplex single-mode fiber connectors. High-performance optical transceivers enable Gigabit Ethernet link distances up to 70 km over single-mode fiber cable. The ports operate in full-duplex mode only. Note: The 1000BASE-ZX Model GBIC is based on proprietary signaling. Nortel Networks recommends that this product be used only with other Nortel Networks 1000BASE-ZX GBICs.
Table 6 1000BASE-ZX GBIC specifications (continued) Type Specifications Distance 70 km Receiver Characteristics Wavelength 1200 to 1550 nm Minimum receiver sensitivity -22 dBm Maximum input power -3 dBm Note: When shorter lengths of single-mode fiber cable are used, there is a risk of overloading the receiver.
