Ubiquiti UISP Fiber GPON CPE
Ubiquiti UISP Fiber Instant GPON CPE (UF-Instant)
The Ubiquiti Fiber Instant (UF-Instant) is compact GPON customer-premises equipment (CPE) in an SFP form factor. It has one SC/APC GPON port on the fiber side and connects directly into a GbE SFP cage, taking its power from the SFP slot. Ubiquiti lists 2.488 Gbps downstream and 1.244 Gbps upstream line rates and a 20 km physical reach. It works only with Ubiquiti's Fiber OLT, not third-party OLTs.
Quick Glance
Key Features
GPON CPE that plugs into an SFP cage
The Fiber Instant has (1) SC/APC ITU-G.984 GPON WAN port and (1) SGMI Ethernet LAN interface, and connects directly into a GbE SFP cage. Power comes from the SFP slot at 3.3V, with a maximum power consumption of 2W.
2.488 Gbps down, 1.244 Gbps up, 20 km reach
Ubiquiti lists a total non-blocking line rate of 2.488 Gbps downstream and 1.244 Gbps upstream, transmitting at 1310 nm and receiving at 1490 nm, with Scrambled NRZ line code and a physical reach of 20 km. The optical module's normal range is 0.5 to 5 dBm TX and -8 to -28 dBm RX.
For Ubiquiti Fiber OLT networks only
Ubiquiti states this device is only compatible with the Fiber OLT and cannot be used with third-party OLTs. It is managed through Ethernet in-band and PON, and its zinc alloy and stainless steel enclosure measures 69.5 x 13.7 x 11.3 mm and weighs 30 g.
Detailed Specifications
Specifications are from Ubiquiti's technical specifications page and official store listing for the UISP Fiber Instant (UF-Instant). Ubiquiti states it works only with its Fiber OLT.
Need-to-Know
- The Fiber Instant is only compatible with Ubiquiti's Fiber OLT. Ubiquiti states it cannot be used with third-party OLTs, so it will not work on an ISP's or another vendor's GPON network.
- It connects directly into a GbE SFP cage and is powered by the SFP slot (3.3V, 2W max). Ubiquiti does not publish a list of host devices in its text; check that your router or switch has a free SFP cage.
- The fiber port is SC/APC. Use a fiber patch cable with an SC/APC connector; no fiber cable is listed as included.
- Ubiquiti rates the module for -10 to 45° C ambient operating temperature and 10 to 90% noncondensing humidity.
