| |||
| Fiber Mode: | |||
| Your choices are... | |||
| Single Mode | Single mode fibers have a small core, only a few times the wavelength of light transmitted, that allows only one mode of light to propagate. Single mode fiber is commonly used with laser sources for high speed, long distance links. | ||
| Multimode | Multimode fibers have a core diameter much larger than the wavelength of light transmitted to allow many modes of light to propagate. Multimode fiber is commonly used with LED sources for lower speed, short distance links. | ||

| |||
| Connector Type: | |||
| Your choices are... | |||
| None | Cables do not have built-in connectors. | ||
| Biconic | Biconic connectors have precision tapered ends for low insertion loss. | ||
| D4 | D4 connectors contain composite zirconia ceramic ferrules for durability. They feature a high-performance threading mounting system and a keyed body for repeatability and intermateability. | ||
| ESCON | ESCON connectors derive their name from their original application, IBM's enterprise system connection (ESCON) for mainframe computers. ESCON connectors are similar to FDDI connectors, but contain a retractable shroud instead of a fixed shroud. ESCON connectors have two 2.55 mm ceramic ferrules and a robust strain relief design. | ||
| FC | FC connectors have an all-zirconia ceramic ferrule for durability, a high-performance threaded mounting system, and a keyed body for repeatability and intermateability. FC connectors are used primarily with single mode fibers and in telephone, instrumentation, and high-speed communication links. | ||
FDDI Courtesy of Cables To Go, Inc. - Copyright 2002 |
Fiber distributed data interface (FDDI) connectors are designed for use in FDDI networks, a LAN technology that uses dual, counter-rotating 100-Mbps fiber optic rings. FDDI connectors are duplex devices that contain two 2.5 mm ferrules. A fixed shroud protects the ferrules from damage. | ||
| LC | LC connectors include a polished, zirconia ceramic ferrule and an push/pull-style housing and latching mechanism. LC connectors are half the size of standard fiber optic cable connectors. They are suitable for both public and private networks. | ||
| Loopback | Loopback connectors are used to test transceiver systems. | ||
| MTP | MTP connectors are threaded and well-suited for high density applications. | ||
MT-RJ Courtesy of Cables To Go, Inc. - Copyright 2002 |
Unlike other fiber optic connectors, MT-RJ connectors hold two fibers with a single ferrule. MT-RJ connectors are a variation of MT connectors, but use a smaller ferrule. | ||
| MU | MU connectors contain a ferrule with a diameter of 1.25 mm. Applications include high-speed data communications, voice networks, telecommunications, and dense wavelength division multiplexing (DWDM). MU connectors are also used in multiple optical connections and as a self-retentive mechanism in backplane applications. | ||
SC Courtesy of Cables To Go, Inc. - Copyright 2002 |
Subscription channel (SC) connectors are coaxial, medium-size devices with a constant 50 impedance and a frequency range of 0 - 11 GHz. They are larger than BNC connectors, but about the same size as Type N devices.
| ||
| SMA | Subminiature-A (SMA) connectors are intended for use on semi-rigid cables in components. They directly interface the cable dielectric without air gaps. They are not intended for permanent connections. | ||
ST Courtesy of Cables To Go, Inc. - Copyright 2002 |
Straight tip (ST) connectors use a quick release, bayonet coupling that requires only a quarter turn to engage or disengage. Built-in keying provides repeatable performance because ST connectors always mate with a coupling bushing in the same way. ST connectors are used in FDDI cabling applications. | ||

| Wavelength | This is the wavelength for which the fiber optic cable was designed. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Numerical Aperture | Numerical aperture (NA) measure a fiber's light-gathering ability. It is the maximum angle to the fiber axis at which light is accepted and propagated through the fiber. NA = sin a, where a is the acceptance angle. NA is also used to describe the angular spread of light from a central axis, as in exiting a fiber, emitting from a source, or entering a detector. | ||

| |||
| Maximum Attenuation | Maximum attenuation is the decrease in signal strength along a fiber optic cable caused by absorption and scattering. Attenuation is usually expressed in dB/km. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Bending Radius | This is the smallest radius that an optical fiber or fiber cable can bend before increased attenuation or breakage occurs. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Operating Temperature | This is the full required range of ambient operating temperature. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||

|
| ||
| Features | |||
| Your choices are... | |||
| Attenuating | Attenuating fibers are used at the ends of optical fiber links to adjust the transmitted signal down to a controlled degree of attenuation, or to provide reflection-free termination. To achieve this, a short piece of ATN is used in the attenuator. | ||
| Graded Index | With graded index fibers, the refractive index of the core is in the form of a parabolic curve and decreases toward the cladding. | ||
| High NA | High NA fibers capture more input with very low, bend-induced attenuation. | ||
| Metallized | Fibers are coated with metals for increased temperature resistance, ease of soldering, and suitability for harsh environments. | ||
| Polarization Maintaining | Fibers maintain the polarization of entering light. | ||
| Other | Other unlisted fiber types. | ||
