GPON OLT‑class SFP module — Designed for use in GPON optical line terminals (OLTs), to transmit data over single‑mode fiber in fiber‑to‑the‑home (FTTH) or fiber‑distribution networks.

Single‑mode fiber support — Works over a single‑mode fiber (SMF) link, suitable for long‑distance fiber optic connections.

SC/UPC optical connector — Uses a standard SC/UPC fiber connector for plug‑and‑play fiber connection.

Asymmetric downstream/upstream data rates — Provides downstream up to ~2.5 Gbps and upstream around ~1.25 Gbps to support GPON traffic distribution (high download bandwidth for clients, adequate upstream for data return).

Wavelengths: 1490 nm (TX) / 1310 nm (RX) — Uses standard GPON wavelength plan: transmitter sends at 1490 nm, receiver accepts at 1310 nm.

Transmit (TX) power: ~1.5 to 5 dBm; Receive sensitivity (RX): as low as –28 dBm — Gives a good optical budget so signal remains viable over typical GPON distances.

Up to 20 km link distance — Suitable for long‑reach fiber links for ISP networks, enterprise fiber backbones, or FTTH distribution up to ~20 km.

Compliant with relevant GPON and SFP standards — Complies with ITU‑T G.984 (GPON) standard, and SFP form‑factor / MSA standards for wide compatibility with SFP slots on OLTs or other GPON‑ready hardware.

Hot‑pluggable SFP form‑factor — Fits into any compatible SFP slot, allowing easy installation or replacement without powering down the equipment.

Supports Distributed Fiber Access / GPON Architecture — Because of its high downstream bandwidth (2.5 Gbps) and long distance reach (20 km), UF‑GP‑B+ is ideal for ISP deployments, large residential/commercial fiber‑to‑home/building networks, or multi‑building campus‑wide fiber distribution.

Good Optical Budget and Reliability for Long‑Distance Links — The combination of TX power range and RX sensitivity gives a healthy optical margin, which helps maintain stable connection quality even over long fiber runs or in cases where fiber quality/attenuation is not ideal.
