What type of connection is used for fiber optic splitters

Fiber optic splitters typically use SC, LC, or FC connectors in APC or UPC styles to interface with fiber cables.

Connector Types

Fiber optic splitters are passive devices that divide a single optical signal into multiple outputs or combine multiple signals into one. To connect splitters to fiber networks, standard fiber optic connectors are used. The most common types include:

  • SC (Subscriber Connector): Widely used in FTTH and PON networks for its push-pull design and reliable performance .
  • LC (Lucent Connector): Smaller form factor than SC, ideal for high-density patch panels and compact installations .
  • FC (Ferrule Connector): Screw-on type, often used in telecom or industrial applications where vibration resistance is important .

Connector Polishing Types

Connectors come in two main polishing styles, which affect signal reflection and insertion loss:

  • UPC (Ultra Physical Contact): Provides low back reflection, suitable for most standard applications .
  • APC (Angled Physical Contact): Features an 8° angled end-face to minimize back reflection, preferred for high-performance networks like GPON or long-distance FTTH deployments .

Splitter Integration

Splitters can be PLC (Planar Lightwave Circuit) or FBT (Fused Biconical Taper) types. Both types are compatible with SC, LC, or FC connectors, and the choice of connector depends on the network design, space constraints, and required performance . Outdoor splitters often come in sealed enclosures with pre-terminated connectors for easy installation and protection against moisture and dust .

Summary

When deploying fiber optic splitters, ensure that the connector type matches the existing fiber infrastructure. SC/APC and LC/APC are commonly preferred for modern FTTH and PON networks due to their low insertion loss and high reliability, while FC connectors are used in specialized or industrial setups. Proper connector selection ensures optimal signal distribution and network performance .
