Fibre splitter is an important accessory in the connection of fibre optic systems. As an integrated waveguide optical power distribution device, it can split an input optical signal into two or more output optical signals. This article will focus on the classification of fibre splitters.
By port configuration
Fibre splitters are divided into 1×2, 1×4, 1×8, 1×16, 1×32 and 1×64 optical splitters depending on the port configuration.
By transmission mode
According to the different modes of transmission, fibre splitter can be divided into single-mode fibre splitter and multi-mode fibre splitter. The working wavelength of single-mode optical splitter is 1310nm and 1550nm, whereas the working wavelength of multi-mode optical splitter is 850nm and 1310nm.
By working wavelength
According to the working wavelength, fibre splitter can be divided into single window optical splitter and double window optical splitter. In this context, window refers to the operating wavelength. Single window optical splitters have only one working wavelength, while double window optical splitters have two working wavelengths.
By manufacturing process
Due to the different manufacturing processes, fibre splitters are divided into planar lightwave circuit (PLC) splitters and fused biconical taper (FBT) optical splitters.
By package type
At present, there are fibre splitters mainly five common packaging types: bare fibre optical splitter, blockless fibre splitter, ABS module fibre splitter, LGX cassette fibre splitter and rack-mount splitter .
Bare Fibre Optical Splitter: As we all know, bare fibre optical splitter has no connector and therefore require a well-protected design of the carrier box or device. Due to its compact design and small size, it can be easily installed in a wiring box, increasing space utilisation and reducing installation costs, making it suitable for FTTH, PON, LAN, CATV and other applications.
Blockless Fibre Splitter: Although similar in appearance to a bare fibre optical splitter, the blockless fibre splitter is designed in a more compact stainless steel tube package, which provides stronger fibre protection. In addition, blockless optical splitters do not require fibre splicing during installation and are typically used in wiring closets or network cabinets.
ABS Module Splitter: The ABS Module Splitter is equipped with an ABS plastic case that protects the internal optical components and optical cables from damage. Moreover, it is compact and can be adapted to different applications and flexibly installed in various wiring closets or enclosures.
LGX Cassette Fibre Splitter: The LGX Cassette Fbire Splitter with its rugged metal housing can be used alone or easily deployed in a standard fibre optic distribution frame or chassis. Apart from this, it is modular, plug-and-play and simple to deploy, which reduces installation risk.
Rack-mount Splitter: Today, 1U and 2U are the two common sizes of rack mount optical splitters , with 1U rack mount optical splitters being more commonly used. Rack-mount splitters are easy to install and maintain, and are widely used in EPON, GPON, FTTX and FTTH networks, providing the ideal solution for high density cabling environments.
