Overview
The Ubiquiti UF-SPLITTER-4 is a passive 1:4 PLC fiber optic splitter designed to distribute an optical signal from a UFiber OLT long-haul connection to multiple UFiber ONUs. It provides one SC/APC input and four SC/APC outputs for GPON fiber distribution.
Optical Performance
The UF-SPLITTER-4 provides 7.4 dB insertion loss with connectors and 0.6 dB uniformity loss. It supports a 1260–1650 nm wavelength bandwidth, with 50 dB return loss across all ports and 55 dB directivity.
Fiber and Connectivity
The splitter uses G657A1 fiber and is terminated with SC/APC connectors. Its 1:4 configuration provides one optical input for distribution to four downstream fiber connections.
Deployment
The UF-SPLITTER-4 is a passive optical component and does not require an external power connection. Its 4.06 m total fiber length provides cable reach for integrating the splitter into compatible fiber distribution infrastructure.
Key Features
- 1:4 passive optical splitting configuration
- 1 SC/APC input and 4 SC/APC outputs
- 7.4 dB insertion loss with connectors
- 1260–1650 nm wavelength bandwidth
- G657A1 fiber construction
Applications
- GPON optical distribution networks
- UFiber OLT to ONU distribution
- Fiber-to-the-premises infrastructure
- Passive optical network deployments
- Small-scale fiber distribution requiring four downstream outputs
DC Supplies Product Note
The UF-SPLITTER-4 is a passive optical splitter, so no external power supply is required. When designing the optical link, account for its 7.4 dB insertion loss and verify SC/APC connector compatibility with the connected OLT and ONU equipment.
