Cisco 1000BASE-SX SFP transceiver module
Cisco's industry-standard SFP is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of IEEE 802.3z- compliant 1000BaseSX, 1000BaseLX/LH, or 1000BaseZX interfaces on a port-by-port basis.
The Cisco GLC-SX-MM operates on ordinary multi-mode fiber optic link spans of up to 550 m in length.
LC-SX-MMD-PCW is a 100% Cisco compatible 1000BASE-SX 550m MMF 850nm SFP transceiver module. This transceiver can be mixed and deployed with Cisco OEM transceivers for seamless network performance and interoperability.PC Wholesale contracts with similar (and sometimes the same) manufacturers as the OEM to build our transceivers. We purchase the same MSA spec, OEM quality optical transceivers as any router, switch, or server manufacturer. Optical transceivers from PC Wholesale carry the same high level of quality in discrete hardware, firmware, packet integrity, and laser strength as the manufacturer's 'approved' OEM. All transceivers are guaranteed for life and returns within 30 days are granted automatically.
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-T SFP for Copper Networks
The 1000BASE-T SFP operates on standard Category 5 unshielded twisted-pair copper cabling of link lengths up to 100 m (328 ft). Cisco 1000BASE-T SFP modules support 10/100/1000 auto negotiation and Auto MDI/MDIX.
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.
1000BASE-LX/LH SFP for Both Multimode and Single-Mode Fibers
The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable. For details on this implementation, refer to http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html.
1000BASE-EX SFP for Long-Reach Single-Mode Fibers
The 1000BASE-EX SFP operates on standard single-mode fiber-optic link spans of up to 40 km in length. A 5-dB inline optical attenuator should be inserted between the fiber-optic cable and the receiving port on the SFP at each end of the link for back-to-back connectivity.
1000BASE-ZX SFP for Long-Reach Single-Mode Fibers
The 1000BASE-ZX SFP operates on standard single-mode fiber-optic link spans of up to approximately 70 km in length. The SFP provides an optical link budget of 21 dB, but the precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors.
When shorter distances of single-mode fiber (SMF) are used, it might be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP at each end of the link whenever the fiber-optic cable span loss is less than 8 dB.
1000BASE-BX10-D and 1000BASE-BX10-U SFP for Single-Fiber Bidirectional Applications
The 1000BASE-BX-D and 1000BASE-BX-U SFPs, compatible with the IEEE 802.3ah 1000BASE-BX10-D and 1000BASE-BX10-U standards, operate on a single strand of standard SMF.
A 1000BASE-BX10-D device is always connected to a 1000BASE-BX10-U device with a single strand of standard SMF with an operating transmission range up to 10 km.
The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices as depicted in Figure 2: 1000BASE-BX10-D transmits a 1490-nm channel and receives a 1310-nm signal, whereas 1000BASE-BX10-U transmits at a 1310-nm wavelength and receives a 1490-nm signal. As shown, the presence of a wavelength-division multiplexing (WDM) splitter integrated into the SFP to split the 1310-nm and 1490-nm light paths.
