As we know, fiber optic connectors are used at both ends of a fiber jumper to achieve cross connections of fibers. There are many types of connectors developed for fiber optic jumper cables. For example, single-mode networks have used FC or SC connectors in about the same proportion as ST and SC in multi-mode installations. To choose a proper fiber optic patch cable, fiber optic connector is a very important factor to consider. LC connector is a common connector type used in fiber optic jumper cables. An LC to LC fiber patch cable is a patch cable terminated at both ends with LC connectors. The following text gives a detailed introduction of LC to LC fiber patch cables.

To better understand LC to LC fiber patch cable, you need to have a basic understanding of LC connector first. LC (Lucent Connector) was first developed by Lucent Technologies as a response to the need by their primary customers for a small and low insertion loss connector. Then the LC design was standardized in EIA/TIA-604-10 and is offered by other manufacturers. The ferrule size of an LC connector is 1.25 mm, half the size of SC connector ferrule. LC connector is rated for 500 mating cycles and its typical insertion loss is 0.25 dB. There are solid reasons that LC connector is a preferred connector type for high-performance network. LC connector has a small size, it borrows split-sleeve construction and a cylindrical ferrule (usually ceramic) from SC connector, and it can have a push-and-latch design providing pull-proof stability in system rack mounts.

There are many options of LC patch cord. The picture below shows LC to LC fiber patch cables.

• Simplex, duplex or multi-fiber assemblies
• PC, UPC, and APC polish types
• Custom fiber optic cable lengths and jacket colors.
• 0.9mm, 1.8mm, 2.0mm, and 3.0mm outer diameter cables
• Jacket types: Riser, PVC, Plenum rated, or LSZH, all RoHS compliant
• Various fiber types and wavelengths, typical 9/125 single-mode fiber (SMF), 50/125 and 62.5/125 multi-mode fiber (MMF)

Armored LC-LC Patch Cable: Armored fiber optic patch cables retain all features of standard fiber patch cords, but are much stronger. Armored fiber optic patch cables will not get damaged even if stepped by an adult and are rodent-resistant. Armored fiber optic cables are actually as flexible as standard fiber optic patch cords. They are made a with similar outer diameter to standard patch cords, making them space saving and strong. And they can be made with different jacket colors and jacket types, and with LC, SC, FC, ST, LC/APC, SC/APC, FC/APC and other types of connectors.

Multi-Core LC-LC Patch Cable: Multi core fiber patch cord are individually reinforced fibers terminated with fiber optic connectors. 2-288 cores are optional and the sub-branch can be 0.9mm and 2.0mm. Multi-core patch cables are widely used for CATV, LANs, Video, active device termination, telecommunication networks etc. They are now RoHS and REACH certified. There are various connectors like LC, SC, SC/APC, FC, FC/APC, ST available.

Mode-Conditioning LC-LC Patch Cable: Mode-conditioning patch cables are used in 1300nm or 1310nm optical wavelength window, and should not be used for 850nm short wavelength window such as 1000BASE-SX. They are made to allow Gigabit 1000BASE-LX single-mode equipment, such as routers and switches, to be used on existing 62.5µm or 50µm multimode cable plants. There are various connectors available, like LC, SC, SC/APC, FC, FC/APC, ST.

There are many types of LC to LC fiber patch cables, including single-mode and multi-mode types, in simplex and duplex versions. These LC patch cords (with UPC or APC polish type) feature various cable jacket types (Riser or Plenum rated, LSZH or PVC, all RoHS compliant). Fiberstore provides all those kinds of LC to LC patch cables. They are fully tested to guarantee top performance. Each assembly is serialized for easy identification and sealed in individual Ziploc bags. Test results are included in each order. They are constructed with high-quality fiberglass and high-grade connectors for high durability and accuracy.
