Custom Optical Components​

What is the fiber optic system?

A fiber optic system is a network designed for transmitting data as pulses of light through strands of fiber made of glass or plastic. These systems are known for their high bandwidth and long-distance communication capabilities, making them essential in modern telecommunications and data networks.


Applications of fiber optic system

Fiber optic technology is used in various applications, including:



  • For high-speed data transmission in telecommunication networks.

Internet and Broadband:

  • Backbone of high-speed internet infrastructure.

Cable Television:

  • Transmission of high-definition television content.

Medical and Industrial Imaging:

  • Flexible fibers are used in endoscopy and imaging in confined spaces.

Military and Aerospace:

  • Due to their resistance to interference and secure nature.

What are passive optical components?

Passive optical systems, on the other hand, rely on components that do not require external power to operate. These components play a crucial role in manipulating light signals as they travel through an optical fiber network.They are simpler and often used in localized networks like FTTH (Fiber To The Home).

Here are some common types of passive optical components:

Fiber optic splice closure

Fiber Optic Splice Closures are protective enclosures used in telecommunications to safeguard fiber optic cable splices. Essential for outdoor networks, they provide a secure, weather-proof housing for joined cables, ensuring continuous optical paths. These closures vary in size,
handling anywhere from a few to hundreds of splices, and are made from durable materials like plastic or metal.

Fiber optic terminal box

A fiber optic terminal box, or fiber terminal box (FTB), is an essential device in fiber optic networks for terminating and managing fiber optic cable connections. It is compact, designed for both indoor and outdoor use, and comes in various sizes to accommodate different numbers of fiber connections.

  • The two main types can be categorized as fiber distribution box and fiber socket box, they are both integral components in fiber optic networks, but they serve distinct purposes and are used in different contexts:
Fiber optic terminal
Fiber Socket

Fiber Optic Patch Panel

A fiber optic patch panel is used for patching fiber cable to the termination enclosure, such as fiber wall cabinets, rack mount fiber cabinets, or rack mount fiber shelves. It is a good option for easy network deployment or moves, adds, and changes.

Fiber optic patch cord, pigtails

A fiber optic patch cord, also known as a fiber optic patch cable or fiber jumper, is a length of fiber optic cable capped at both ends with connectors that allow it to be rapidly and conveniently connected to an optical switch, router, or other telecommunication/network equipment. Its primary purpose is to connect one device to another for signal routing.A fiber optic pigtail is similar to a patch cord but has a connector on only one end and a length of exposed fiber at the other end.

MTP® & MPO Cable

MPO (Multi-Fiber Push On) cables are capped with MPO connectors at either end. MPO fiber connector is for ribbon cables with more than 2 fibers, which is designed to provide multi-fiber connectivity in one connector to support high bandwidth and high-density cabling system applications. MTP® cables, short for (Multi-Fiber Pull Off), are equipped with MTP® connectors at either end. MTP® connector is a trademark by US Conec for a version of the MPO connector with improved specifications. So MTP® connectors are fully compliant with all generic MPO connectors and can interconnect directly with other MPO based infrastructures.

Removable Housing for MTP® Cable


Wavelength Division Multiplexing (WDM) is a technology used in fiber optic communications to combine and transmit multiple optical carrier signals on a single fiber optic cable by using different wavelengths (colors) of laser light. This method effectively increases the capacity of a single fiber to carry multiple independent data streams.

WDM fiber

Fiber optic splitter

A fiber-optic splitter, or beam splitter, is a key device in optical networks, built on a quartz substrate integrated waveguide for optical power distribution. This passive device, crucial in optical fiber links, has multiple inputs and outputs.

Fiber optic adapter

Fiber optic adapters, or fiber couplers, are devices used to connect two fiber optic cables in a network. They come in various types to match different connectors, like SC, LC, ST, FC, and MTP/MPO. These adapters contain alignment sleeves for precise ferrule alignment, ensuring minimal signal
loss. They are available for both single-mode (long-distance, high-speed) and multimode (short-distance) fibers and come in simplex or duplex configurations.

Optic Adapter7

Fiber optic attenuator

An optical attenuator, also known as a fiber optic attenuator, is designed to reduce the power level of an optical signal, either in free space or in a fiber optic cable.
