Cisco 1000BASE-SX SFP transceiver module – GLC-SX-MMD=

Cisco SFP Modules

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

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 μm multimode fiber links up to 550 m and on 62.5 μm Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m. It can support up to 1km over laser-optimized 50 μm 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)

Note: Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section.

Table 1 provides cabling specifications for the SFPs that you install in the Gigabit Ethernet port. Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (multimode and single-mode fiber) is 6.5 feet (2 m).

Optical specifications

Table 2 specifies the optical parameters for the SFPs. Both receiver power and channel insertion loss specifications must be met for guaranteed operation.

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.

Table 3 lists temperature range and DOM support information for the SFPs.

Warranty

●      Standard warranty: 5 years

●      Expedited replacement available via a Cisco SMARTnet^® Service support contract
