LC Product in Fiber Optic

What does LC Mean in Fiber Optic?

LC stands for a type of optical connector of which the full name is Lucent Connector. It comes with the name because the LC connector was firstly developed by Lucent Technologies (Alcatel-Lucent for now) for telecommunication applications. It uses a retaining tab mechanism and the connector body resembles the squarish shape of SC connector. Similar to the SC type connector, LC fiber optic connector is easy to plug in or remove, providing a secure, precisely aligned fit conforming to TIA/EIA 604 standards. Until now, it is still one of the most popular fiber optic connectors in the fiber optic market.

What does LC Connector Feature?

Owing to the different applications and manufacturers’ preference, not all the LC connectors are created the same. However, there are still some general features that LC connectors have:

Small form factor：LC connector is half the dimension of regular connectors such as SC, FC, and ST connectors. The compact and fool-proof design enables LC connectors to be deployed in high-density applications.

Low insertion loss performance: The LC connector has six-position tuning feature to achieve very low insertion loss performance by optimizing the alignment of the fiber cores.

What are LC Fiber Optic Solutions?

LC fiber optic solutions: LC fiber connectors, LC fiber patch cables, LC fiber adapter, LC fiber patch panels, LC fiber attenuators and so on, each available for multiple needs in applications such as telecommunications networks, LANs, etc.

LC Fiber Connector Solution

Generally, there are two versions of LC connectors: fiber patch cable connector and behind-the-wall (BTW) connector.

LC Connectors for Jumpers

There are two types of LC connectors for jumpers. LC 1.5 to 2.0mm connectors are designed to mount onto 1.5 to 2.0mm fiber cordage. While LC 3.0mm connectors are designed to mount on 3.0mm cordage. Simplex and duplex fibers are both available for the connectors. The following image shows the two LC connectors with different core diameters.

LC BTW Connectors

The BTW connector is a shorter version of LC designed for 0.9mm buffered fiber. Typically, it is utilized on the back side of the equipment. There is one type of LC BTW connector which is based on the unibody connector—LC BTW unibody connector.

LC Fiber Patch Cable Solution

Standard LC Fiber Patch Cable

LC-LC fiber patch cable with two LC fiber connectors terminated at both ends is the most commonly used fiber optic cable type in the industry. Compared with other common fiber optic cables, LC fiber cables offer high density and reliable performance in most applications. Standard LC fiber patch cables can be divided into single mode (OS1/OS2) and multimode (OM1/OM2/OM3/OM4/OM5), duplex and simplex fiber cable types.

Uniboot LC Fiber Patch Cable

To cope with the “high density” trend in data centers, uniboot LC fiber cable is born.

Ultra Low Loss LC Fiber Patch Cable

Ultra low loss LC fiber optic cable is one of the highest performance fiber patch cables, featuring a rugged single-piece body connector with a latch trigger up to 4x stronger than standard connectors. Standard LC fiber cables maintain an insertion loss of 0.3 dB, while ultra low loss LC fiber cables produce an insertion loss of only 0.12 dB, providing exceptional performance and lower power consumption. This fiber cable type typically has a Grade B connector ensuring ultra low IL and RL and avoiding the production of error code and worse signal. Ultra low loss LC fiber optic cable is available in single mode and multimode cable types.

Armored LC Fiber Patch Cable

Armored LC fiber patch cables keep the similar feature as standard LC fiber patch cord. But compared with standard LC fiber patch cords, they are made of armored fiber optic cables and are stronger and more robust so as to protect the cable from rodent bite, pressure, or twist. Though they are more robust than standard cables, they are actually as flexible as the standard ones and hard to break when they are bent. Besides, the outer diameter of armored LC fiber patch cable is similar to a standard LC fiber patch cable, thus it saves much space.

Mode-Conditioning LC Patch Cable

Mode-conditioning LC patch cables combine multimode fiber cable and single mode fiber cable with calibration. They are built in the form of the general duplex LC patch cables, making it convenient to install cables without the need for other additional assemblies. It is designed for long wavelength Gigabit Ethernet applications. For some occasions that standard multimode LC patch cord can not be directly plugged into some 1G/10G optical modules, mode-conditioning LC patch cables will eliminate this issue, saving the cost of upgrading fiber plant for customers. The commonly used mode-conditioning LC patch cables include LC to LC connector, LC to SC connector, and LC to FC connector with multimode fiber optic cables.

LC/MTP/MPO/SC/FC/ST-LC Breakout Fiber Patch Cable

Breakout cable, or called fall-out cable contains several fibers, each with their own jacket, and then encased by a single common jacket. The fiber counts vary from 2 to 24 fibers. There are two cases for LC breakout cable. One is that breakout fiber patch cable has the same connectors on each end, which means both the ends are LC connectors. For the other case, there are different connectors on each end of the fiber. One end is LC and the other can be MTP, MPO, ST, FC, etc. Breakout fiber patch cables are widely applied for telecommunication networks, data center communications, etc., providing you with the advantage of multiple connectors without having to change the entire system.

LC Fiber Adapter & Patch Panel Solutions

Fiber optic adapters or fiber couplers are designed to connect two fiber patch cables together. LC fiber adapter features a self-adjusting mechanism designed to accommodate patch panels of thickness between 1.55 to 1.75 mm. It is available in single mode, multimode, simplex and duplex options. LC simplex adapter connects one LC connector pair in one module space. While LC duplex adapter connects two LC connector pairs in one module space.

Fiber patch panels are also known as fiber distribution panels. The rack size can be 1U,2U, etc. 1U is the most commonly used rack size in data centers. The number of ports on a fiber optic patch panel is actually not limited, they can vary from 12, 24, 48,64,72, and even more. Both LC fiber adapter and LC fiber patch panels are ideal for high-density fiber cabling. LC fiber patch panel can be pre-loaded or unloaded with LC fiber adapters for both single mode and multimode fiber, providing a flexible and easy way for the server room, data center, and other high-density fiber installations.

LC Fiber Attenuator Solution

LC fiber attenuators are another commonly used LC devices. An LC optical attenuator is a passive device used to reduce the power level of an optical signal in the optical network where erbium-doped amplifiers are being used.
