Fiber media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fiber optics. Media converter types range from small standalone devices and PC card converters to high port ...
The yellow cables are single-mode duplex fiber optic connections. There are two basic types of optical fiber used for 10 Gigabit Ethernet: single-mode (SMF) and multi-mode (MMF). [22] In SMF light follows a single path through the fiber while in MMF it takes multiple paths resulting in differential mode delay (DMD).
SFP modules support a variety of distances via multi-mode and single-mode optical fiber as shown in the table below. SFP modules use duplex fiber cabling with LC connectors. SFP-DD modules are used in high-density applications that need to double the throughput of traditional SFP ports.
Gigabit interface converter (GBIC) is a standard for transceivers. First defined in 1995, it was used with Gigabit Ethernet and Fibre Channel . By standardizing on a hot swappable electrical interface, a single gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber , at lengths of hundreds of ...
1000BASE-LX is specified to work over a distance of up to 5 km over 10 μm single-mode fiber. 1000BASE-LX can also run over all common types of multi-mode fiber with a maximum segment length of 550 m. For link distances greater than 300 m, the use of a special launch conditioning patch cord may be required. [28]
1 to 1. 25 Gbit/s multi-mode fiber, LC connector, with black or beige extraction lever [2] SX – 850 nm, for a maximum of 550 m at 1. 25 Gbit/s (gigabit Ethernet). Other multi-mode SFP applications support even higher rates at shorter distances. [20] 1 to 1. 25 Gbit/s multi-mode fiber, LC connector, extraction lever colors not standardized
Most WDM systems operate on single-mode optical fiber cables which have a core diameter of 9 μm. Certain forms of WDM can also be used in multi-mode optical fiber cables (also known as premises cables) which have core diameters of 50 or 62.5 μm. Early WDM systems were expensive and complicated to run.
The core of a single-mode fiber is smaller (< 10 micrometers) and requires more expensive components and interconnection methods, but allows much longer and higher-performance links. Both single- and multi-mode fiber is offered in different grades.
