What are the data rates of the UF-GP-B+?

Downstream rate is 2.5 Gbps (2.488 Gbps precisely), upstream is 1.25 Gbps (1.244 Gbps). These GPON rates use GEM encoding and support up to 128 ONUs per port in UFiber OLT systems like UF-OLT, ideal for high-density deployments.

What is the maximum transmission distance?

Up to 20 km over single-mode fiber, backed by a 33 dB guaranteed link budget (min 29.5 dB). This accommodates splitter losses in PON trees, with TX power 1.5-5 dBm at 1490 nm and RX sensitivity -28 to -8 dBm at 1310 nm.

What connector and media does it use?

Single SC/UPC connector for single-mode fiber (SMF). TX wavelength bandwidth 20 nm (1480-1500 nm), RX 100 nm (1260-1360 nm), ensuring compatibility with standard GPON infrastructure and easy field termination.

Does it support diagnostics?

Yes, full DDM/DOM support per SFF-8472 for monitoring TX/RX power, temperature, voltage, and laser bias. This enables proactive maintenance in enterprise networks, complying with ITU-T G.984.2 and SFP MSA standards.

What is the operating temperature range?

0°C to 70°C standard range, suitable for indoor OLT installations. Storage is -40°C to 85°C, with 5-85% humidity tolerance, and certifications include CE, RoHS, Class 1 FDA, IEC60825-1 for safe deployment.

Is it compatible with Ubiquiti OLTs?

Designed for UFiber OLT and UF-OLT-4 GPON ports. Plug-and-play SFP form factor supports 1024 total ONUs across 8 ports, with asymmetrical GPON for FTTH/ISP use cases up to 20 km.
