A modular platform for organizing passive optical splitter components in a defined rack-mount layout.
Optical distribution projects need predictable placement for passive splitting while accommodating distinct fiber types and coupling requirements.
A single fixed splitter configuration may not suit every link. Fiber type, operating wavelength, connection interface and distribution ratio all affect the component selection.
A common 1U rack format accepts purpose-selected optical splitter modules, making the physical distribution arrangement easier to specify and document.
The rack is the physical platform; each installed module defines an optical function. Splitter topology and power distribution are separate parameters.
Single-mode or multimode, according to the selected module

According to splitter type
Three inputs define most of the technical selection process. They are kept separate from the measured component characteristics below.
Choose the required optical topology. For two-way couplers, confirm the power-split ratio against the channel-loss reference and module design.
Choose from the documented single-mode or multimode families and specify the intended wavelength band before matching optical performance.
The module ordering guide lists LC/UPC and LC/APC connector options. Match connector polish to the link specification.
The same mechanical module format may also accommodate WDM components or optical combiners, as noted in the datasheet. This is a platform design option, not a claim that every such function is supplied as a standard stock module.
The published data below comes from the Fibernet Rev. 1.0 datasheet (March 2019). Coupler ratio values are presented separately to avoid mixing optical characteristics with module capacity.

Technical distinction: A module’s 1×2 or 1×4 design describes its optical topology. The 50/50 through 1/99 values above describe coupler power distribution. They should not be treated as interchangeable specifications.
These are the product identifiers documented in the datasheet. The exact module code suffix and supplied quantities should be confirmed with Fibernet.
The rack-mount platform supporting up to 30 optical modules.
Specify 1×2 or 1×4 and the required LC/UPC or LC/APC connector interface.
