Cisco SFP Modules Overview
As we all know, Cisco is one of the most famous brands in the field of telecommunications. Cisco compatible SFP transceiver modules are widely used for Gigabit Ethernet applications in data centers and network systems. 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.
The 1000BASE-T SFP operates on standard Category 5 unshielded twisted-pair copper cabling of link lengths up to 100 m. Cisco 1000BASE-T SFP modules support 10/100/1000 auto negotiation. The following is Fiberstore's Cisco compatible 10/100/1000BASE-T copper SFP transceiver, compliant with the Gigabit Ethernet standard as specified in IEEE STD 802.3 and can fully satisfy the 10/100/1000BASE-T application.
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. For example, Fiberstore's Cisco SFP-GE-S compatible 1000BASE-SX SFP operates on legacy 50 μm multimode fiber links up to 550 m with digital diagnostics monitoring function.
The 1000BASE-LX/LH SFP (GLC-LH-SMD) is compatible with the IEEE 802.3z 1000BASE-LX standard and 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.
The 1000BASE-EX (GLC-EX-SMD) 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.
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.
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.
Fiberstore's SFP transceivers for Gigabit Ethernet are designed for the Gigabit networks with different types to fit for 1000Base-SX, 1000Base-LX/LH, 1000Base-EX, 1000Base-ZX and 1000Base-T applications. All these modules come with digital diagnostics monitoring (DDM) functions and are very cost-effective.
