The challenge
More endpoints. A finite optical budget.
Each splitting topology has its own insertion-loss, uniformity and polarization-dependent-loss characteristics. Connector terminations also influence the completed link’s measured loss.

Fiber Infrastructure / Passive Optical Components / PLC Splitters
01 / Engineering decision
A splitter is more than an output count.
Choosing a PLC splitter means balancing the number of optical paths with signal attenuation and the physical constraints of the distribution point. A configuration that fits on paper also needs to fit inside the available housing.
The Fibernet approach
Match the topology to the installation.
Choose a listed 1-input or 2-input splitter configuration, then specify its fiber, package, lead length and interface. Performance data remains visible while you design the assembly.
02 / Optical architecture
Choose the output architecture before the enclosure.
The published family includes 1×N and selected 2×N devices. Use the data below to compare the optical tradeoffs before finalizing a cable or module format.

Showing all 12 configurations
Measurement basis: values are from the November 2014 datasheet, tested at 1310 nm and 1550 nm at room temperature; insertion loss excludes connector loss. The source specifies a further 0.3 dB per connector pair for PC/UPC or 0.4 dB per pair for APC. Confirm specifications for the ordered configuration.
03 / Physical integration
Packaging for different distribution environments.
The datasheet lists multiple mechanical formats. Their suitability depends on the chosen channel count; not every splitter fits every package.

05 / Specify your assembly
From optical requirement to an orderable configuration.
Use the FPLC ordering structure to define the key parameters. A completed part number must be checked for compatibility and current availability.
01
Channel topology
Choose the required 1×N or 2×N port count.
02
Fiber & package
Match fiber type and enclosure code to the application.
03
Input / output
Specify lead styles, termination method and routing.
04
Pigtail length
Define the required length for the installation layout.
05
Connector polish
Select compatible connector and polish combinations.
Fibernet operates according to ISO 9001:2015, ISO 13485:2016, and AS9100D quality management standards. These company-level standards do not establish certification of any particular splitter configuration.
06 / Applications
Optical distribution where a defined passive split is needed.
The supplied datasheet identifies several deployment contexts. Each installation should be evaluated against its optical link requirements.
FTTx access networks
Divide an optical feeder into the planned set of downstream distribution paths.
Passive Optical Networks
Support PON topology design with a defined passive splitting stage.
CATV / LAN infrastructure
Integrate an optical coupler where the system architecture calls for signal splitting.
Test and validation setups
Introduce a known split topology in a controlled optical test configuration.
