Two Modes Of Cisco SFP From Fiberstore


What is the SFP Transceiver? From the fiber optic technology we know that.SFP(small form-factor pluggable) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA).Due to its smaller size, SFP obsoletes the formerly ubiquitous gigabit interface converter (GBIC); the SFP is sometimes referred to as a Mini-GBIC although no device with this name has ever been defined in the MSAs.Fiberstore supply various kinds of SFP module 100% compatible with Cisco, HP, Juniper, Netgear, DELL and so on.

Cisco SFP transceivers have a variety of different transmission and receiving type, the user can select the appropriate transceiver for each link, to provide the optical performance can be achieved based on the available fiber type (such as a multimode fiber or single mode fiber).Our comaptible cisco module includes: multimode optical modules GLC-SX-MM; Single-mode optical module GLC-LH-SM, GLC-ZX-SM; SFP copper module GLC-T; DWDM/CWDM SFP; 2.125G SFP transceiver module; 4G SFP module; BIDI SFP optical transceiver; SFP with DDM transceiver such as SFP-GE-S .Today we will mainly introduce two modes of Cisco SFP: GLC-SX-MM,GLC-LH-SM. They are with duplex LC interface and supporting data-rate of 1.25Gbps.

Cisco GLC-SX-MM for Multimode Fiber Only:

Cisco GLC-SX-MM is a commonly used SFP transceiver which is 1000Base-SX SFP for multimode fiber and works at 850nm wavelength. It can reach 550 meter working distance via 50/125 multimode fiber, and 220 meters on 62.5/125 multimode fibers. GLC SX MM SFP is hot swappable module that fits for Gigabit Ethernet port or slot and link the port with the network. Fiberstore supply Cisco equivalent GLC SX MM SFP fiber optic transceiver at very competitive prices and fast delivery.

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.

Cisco GLC-LH-SM for Both Multimode and Single-Mode Fibers:

Cisco GLC-LH-SM is a SFP fiber optic transceiver working at 1310nm wavelength, it could use with both multimode optical fiber and single mode optical fiber, it is small size transceiver with LC interface and it is hot swappable, easy to use, no need further configuration. GLC LH SM is used in Gigabit network and its max working distance is 40km over SMF at 1.25Gbps transfer rate.

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.
