Cisco GLC-SX-MMD 1000BASE-SX SFP Transceiver Module MMF 850NM Cisco GLC-SX-MMD= 1000Base SX SFP Transceiver Module, MMF 850NM, DOM 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). Table 1. SFP Port Cabling Specifications Product Wavelength (nm) Fiber Type Core Size (μm) Modal Bandwidth (MHz* Km)*** Operating Distance (m) 1000BASE-SX 850 MMF 62.5 160 (FDDI-grade) 220 (722 ft) 62.5 200 (OM1) 275 (902 ft) 50 400 (400/400) 500 (1,640 ft) 50 500 (OM2) 550 (1,804 ft) 50 2000 (OM3) 1000 (3281 ft) * A mode-conditioning patch cord, as specified by the IEEE standard, is required regardless of the span length. Note how the mode conditioning patch cord for 62.5-μm fibers has a different specification from the mode-conditioning patch cord for 50-μm fibers. ** ITU-T G.652 SMF as specified by the IEEE 802.3z standard. *** Specified at transmission wavelength. 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. Table 2. Main Optical Parameters Product Transmit Power Range (dBm) Receive Power Range (dBm) Maximum Channel insertion loss in dB (by fiber type)* Transmit and Receive Wavelength Range (nm) 1000BASE-SX -3 to -9.5 0 to -17 2.4 (FDDI-grade) 2.6 (OM1) 3.4 (400/400) 3.6 (OM2) 5 (OM3) 770 to 860 * Maximum channel insertion loss is defined for maximum distance guaranteed as specified in Table 1 and by fiber type. When links are deployed over shorter distances, additional channel insertion loss may be allowed. 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. Table 3.
