singlemode fiber

An optical fiber with a core diameter of less than 10 microns. Used for high-speed transmission over long distances, it provides greater bandwidth than multimode, but its smaller core makes it more difficult to couple the light source. Increasingly, singlemode fiber is used for shorter distances. When singlemode fiber is used in shorter distances, such as a campus or metropolitan area network (MAN), step-index fiber is used. For longer distances and for transmitting multiple channels (WDM), dispersion-shifted fiber is used. Contrast with multimode fiber. See dispersion-shifted fiber, step-index fiber, dispersion and fiber optics glossary.

The ELX-7100 transceiver provides a reach of 300 meters over standard multimode fiber, including the widely deployed "FDDI grade" legacy multimode fibers, and 10 kilometers over singlemode fiber. In addition, an extended-reach version of the ELX-7100 will reach 40 kilometers over singlemode fiber.
An extended reach version (ELX4) is now available, designed to transmit up to 40 km over standard singlemode fiber. A multiple protocol version (MP) is also being introduced, which operates over any protocol from 1.0 Gbps to 3.2 Gbps per lane and dissipates half the power of current 1,300 LR and LX4 modules.
Fully standardized in ITU as a G.652.C fiber, AllWave, zero water peak fiber, offers 100nm more useable spectrum than conventional (G.652) singlemode fiber.
Singlemode fiber optic cable has a much higher bandwidth than multi-mode cable but is more sensitive to bending losses.

FiberPlex's new FOI-6010 was introduced earlier in 2013 as a universal SFP/SFP+ (small form-factor pluggable) frame that can interchange SFP modules for a variety of formats and uses, including interfacing singlemode fiber cable into existing multimode fiber build-outs.

Models are available for both multimode and singlemode fiber and in a wide range of optical output power levels.
They extend distances up to 2km over multimode fiber optic cable and up to 100km over singlemode fiber optic cable.
Because of its small core of 8 to 10 [mu]m, the singlemode fiber only permits a fundamental wave to propagate, as shown in Figure 4.
