Telecom Industiral Quality 1G SFP LX SMF Optical Module

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.

Specifications

The small form-factor pluggable (SFP) 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). It interfaces a network device motherboard (for a switch, router,media converter or similar device) to a fiber optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors.[1] SFP transceivers are designed to support SONET, gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsolesces 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.SFP transceivers are available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required optical reach over the available optical fiber type (e.g. multi-mode fiber or single-mode fiber). Optical SFP modules are commonly available in several different categories:for multi-mode fiber, with black or beige[1] extraction leverSX - 850 nm, for a maximum of 550 m at 1.25 Gbit/s (gigabit Ethernet) or 150m at 4.25 Gbit/s (Fibre Channel)[2]for single-mode fiber, with blue[1] extraction leverLX - 1310 nm, for distances up to 10 kmEX - 1310 nm, for distances up to 40 km [3]ZX - 1550 nm, for distances up to 80 km, with green extraction lever (see GLC-ZX-SM1) [4][5]EZX - 1550 nm, for distances up to 160 km [6]BX - 1490 nm/1310 nm, Single Fiber Bi-Directional Gigabit SFP Transceivers, paired as BS-U and BS-D for Uplink and Downlink respectively, also for distances up to 10 km.[7][8] Variations of bidirectional SFPs are also manufactured which use 1550 nm in one direction.1550 nm 40 km (XD), 80 km (ZX), 120 km (EX or EZX)SFSW – Single Fiber Single Wavelength transceivers, for bi-directional traffic on a single fiber. Coupled with CWDM, these double the traffic density of fiber links.[9][10]CWDM and DWDM transceivers at various wavelengths achieving various maximum distancesfor copper twisted pair cabling1000BASE-T - these modules incorporate significant interface circuitry[11] and can only be used for gigabit Ethernet, as that is the interface they implement. They are not compatible with (or rather: do not have equivalents for) Fibre channel or SONET.
