Function of splice boxes in fiber optic networks

Splice boxes, also known as fiber optic splice enclosures or fiber splice closures, are essential components in fiber optic networks. Their primary function is to protect and manage the spliced fiber optic cables, ensuring they remain secure, well-organised, and unaffected by environmental factors. The key elements within a splice box include the splice cassette, responsible for accommodating the fiber cables and their extra lengths, as well as the front panel, which features a variety of connectors for transmitting signals.
The splice box functions as a connection point between the fiber optic installation cable and pigtails. Within the splice cassette, the fiber optic cable is carefully spliced and separated into pigtails. The splice cassette is removable and stackable and can be assembled without tools. In addition, the front panel of the splice box can be removed to gain easy access to the cassette and splice fibres to different fiber optic connectors
All common connector types are possible, e.g. LC, SC, E2000® or ST. The splice boxes are usually installed in 19″ network or server cabinets. Once installed, active components (switches, media converters) can be exchanged or extended with little effort. All you have to do is reconnect the fiber optic patch cables or plug in additional ones. 
Save valuable time during installation and order splice boxes from EFB-Elektronik already fully equipped and ready to splice. The boxes are available in grey (RAL 7035) or black (RAL 9005). The equipment options are very extensive. EFB-Elektronik therefore offers customised equipping of the splice boxes.

Areas of application for splice boxes

Rechenzentrum
Data centres
Especially in data centers with a high number of connections, splice boxes are essential to ensure easy management and scalability of connections. Boxes maintain organised cable management and secure and redundant cabling.
Büro
Office
In offices, splice boxes serve as central hubs for network connections between departments, to facilitate maintenance and troubleshooting. The boxes ensure an organised cable structure and contribute to an aesthetic working environment. They also help to protect the network from unauthorised access.
Campus
Campus
Many people use the network at colleges and universities. Splice boxes enable network segmentation for increased security. They facilitate network expansion to new buildings and equipment and ensure reliability through redundancy. They also support the connection of various services such as printers, payment systems, video cameras and research instruments.

Varieties of splice boxes

Splice boxes protect the fusion or mechanical splices of fiber optic cables. These splices are typically delicate and must be safeguarded against physical damage and environmental factors.
There are various types of splice boxes, designed to meet specific environmental and application requirements:
  • 19-inch splice boxes: Splice boxes in 19" format are the most common. The standard size fits into standardised racks and network cabinets and therefore enables seamless integration into existing network infrastructures.
  • Dome Splice Closure: These are often used for aerial or buried applications. They have a dome-like structure with gasket-sealed access ports for cable entry and exit.
  • Vertical Closure: Vertical closures are suitable for applications with limited lateral space. They have a vertical orientation, which allows them to be installed in confined areas.
  • Horizontal Closure: These closures are installed horizontally and are often used in wall-mounted or rack-mounted configurations.
  • Splice Housing for DIN Rail: These closures are used in long fibre optic cable runs where splices are required to repair or extend the network.
  • Inline Splice ClosureInline Splice Sleeeves are designed for use in long-distance fiber optic cable runs where splicing is necessary to repair or extend the network.
  • Fiber Distribution Hub (FDH): FDH closures are used in fiber-to-the-home (FTTH) networks to distribute fiber optic connections to multiple households. They often include a splitter for signal distribution.

Structure of an assembeld splice box

Bestückte Spleißbox
1.Fiber pigtails with through-dyed, color-coded primary and secondary coating.  

2.Plugged into the feedthrough adapters according to colour code DIN VDE0888. 

3. Proper fiber guidance in the splice box.  

4. Fibers inserted into the splice cassette, set down and shortened.
Colourcode DIN VDE0888
The colour coded pigtails are according to colour code DIN VDE0888 into the feedthrough adapters. The 900µ fibers are properly laid through the fiber guides in the splice box and inserted into the splice cassette. In the splice cassette the secondary coating (900µ) of the fibers is deposited in a length-adjusted manner. The 250µ fibers are guided in the splice cassette and shortened to the same length. The coloured primary coating (250µ) makes colour allocation easy.
