UISP Fiber - Accessories

This article showcases the benefits of using UFiber GPON equipment using topology examples. Readers will also learn how to start implementing UFiber networks utilizing an extensive array of Ubiquiti equipment.

The UFiber GPON Accessories

Back to Top

When building a network with UFiber equipment it is required to use accessories to successfully connect the UFiber OLTs and UFiber ONUs. Ubiquiti offers an extensive collection of accessories that allows you to easily and quickly set up a UFiber GPON network. The advantage of using the official accessories is that they are fully compatible and supported on all UFiber products.

The following UFiber accessories are available:

Accessory / Description
UF-GP-C+ UFiber GPON SC/UPC fiber module used to populate the other PON ports on the OLT. The UF-GP-C+ module is capable of a higher transmit power than the UF-GB-B+ module.
UF-GP-B+ UFiber GPON SC/UPC fiber module used to populate the other PON ports on the OLT.
UF-Nano UFiber GPON ONU featuring one (1)  SC/APC PON port and one (1) Gigabit Ethernet port. The UF-Nano is powered by 24V Passive PoE.
UF-LOCO UFiber GPON ONU featuring one (1)  SC/APC PON port and one (1) Gigabit Ethernet port. The UF-LOCO can be powered by 24V Passive PoE or the included Micro-USB adapter.
UF-WIFI UFiber GPON ONU featuring one (1)  SC/APC PON port, four (4) Gigabit Ethernet ports and Wireless connectivity (Wi-Fi). The UF-WIFI can be powered by 24V Passive PoE or the included 24V power adapter.
RPS-AC-100W AC/DC Power module designed for usage with the modular power bays on the UF-OLT.
RPS-DC-100W DC/DC Power module designed for usage with the modular power bays on the UF-OLT.
UF-SM-PATCH-UPC-APC SC/UPC to SC/APC fiber patch cable (1.5m) with male connectors used to connect the UFiber OLT to a PLC splitter.
UF-SM-PATCH-APC-APC SC/APC to SC/APC fiber patch cable (1.5m) with male connectors used to connect a PLC splitter to the UFiber ONUs.
UF-SPLITTER SC/APC to SC/APC PLC splitter with male connectors. Available in four different variations: UF-SPLITTER-4  UF-SPLITTER-8  UF-SPLITTER-16  UF-SPLITTER-32
UF-ADAPTER-APC SC/APC to SC/APC adapter with female connectors used to inter-connect the male connectors on the patch cables and PLC splitters.
UF-SM-10G Single-Mode Fiber 10Gbps SFP+ module with LC (2) connector.
UF-SM-10G-S Single-Mode Fiber 10Gbps SFP+ module with LC (1) connector.
UF-MM-10G Multi-Mode Fiber 10Gbps SFP+ module with LC (2) connector.
UF-RJ-45-10G Copper 10Gbps SFP+ module with RJ45 connector.
UDC-1 / UDC-2 / UDC-3 Direct Attached Copper (DAC) 10Gbps cable in 1m, 2m and 3m lengths.

UFiber Topology Example

Back to Top

In the topology example below, the traffic flows from the WAN to a router (for example the ER-8-XG), continues on to a switch (optional) and finally to the OLT. All of these devices are interconnected using 10Gbps fiber SFP+ modules or DAC cables (for example the UF-SM-10G) using the SFP+ slots.

Example UFiber GPON topology using the UFiber OLT, UFiber Nano G ONU and the different accessories.

The UFiber OLT can then be populated with either class B+ (UF-GP-B+) or class C+ (UF-GP-C+) GPON modules. Each module will connect to a PLC splitter supporting up to 128 UFiber ONUs (UF-Nano, UF-LOCO or UF-WIFI) on each PON port.

The SC/UPC to SC/APC fiber cable that inter-connects the UFiber OLT to the PLC splitter is known as a feeder cable. In this example, the UF-SM-PATCH-UPC-APC accessory is used. There are different options available for the PLC splitter:

• UF-SPLITTER-4 Split ratio of 1:4 with an insertion loss of -7.4 dB with connectors.
• UF-SPLITTER-8 Split ratio of 1:8 with an insertion loss of -10.5 dB with connectors.
• UF-SPLITTER-16 Split ratio of 1:16 with an insertion loss of -13.7 dB with connectors.
• UF-SPLITTER-32 Split ratio of 1:32 with an insertion loss of -17.0 dB with connectors.

At the other end of the PLC splitter the UF-SM-PATCH-APC-APC accessory is used to inter-connect the PLC splitter to the ONU. This SC/APC to SC/APC fiber cable is known as the drop cable.

Because the feeder cable, PLC splitter(s) and drop cable(s) all use male connectors, the UF-ADAPTER-APC accessory is used to inter-connect the SC/APC ends of the cables.
