Cisco GLC-SX-MMD= Compatible 1000BASE-SX SFP 850nm 550m Industrial DOM LC MMF Transceiver Module

Cost-effective Small Form-factor Pluggable (SFP) transceivers for Gigabit Ethernet applications

Product Overview

The industry-standard Cisco® Small Form-Factor Pluggable (SFP) Gigabit Interface Converter (Figure 1) links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot. Optical and copper models can be used on a wide variety of Cisco products and intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.

Features and Benefits

• Hot swappable to maximize uptime and simplify serviceability
• Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate”
• Robust design for enhanced reliability
• Supports digital optical monitoring (DOM) capability

1000BASE-SX SFP for Multimode Fiber Only

The 1000BASE-SX SFP, compatible with the IEEE 802.3z 1000BASE-SX standard, operates on legacy 50 ?m multimode fiber links up to 550 m and on 62.5 ?m Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m. It can support up to 1km over laser-optimized 50 ?m multimode fiber cable.

Product Specifications

Cabling and Connectors

Connectors include the following:

• Dual LC/PC connector (1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX and 1000BASE-ZX)
• Single LC/PC connector (1000BASE-BX-D and 1000BASE-BX-U)
• RJ-45 connector (1000BASE-T)

Dimensions

Dimensions (H x W x D): 8.5 x 13.4 x 56.5 mm. Cisco SFPs typically weigh 75 grams or less.

Environmental Conditions and Power Requirements

Operating temperature range:

• Commercial temperature range (COM): 0 to 70°C (32 to 158°F)
• Extended temperature range (EXT): -5°C to 85°C (23 to 185°F)
• Industrial temperature range (IND): -40 to 85°C (-40 to 185°F)
• Storage temperature range: -40 to 85°C (-40 to 185°F)

Cisco SFP modules typically consume up to 1W per SFP port, with the exception of the Compact SFP (GLC-2BX-D) consuming up to 1.5W.

Warranty

Standard warranty: 1 year

Extended warranty (option): Available under a Cisco SMARTnet® Service support contract for the Cisco switch or router chassis
