- SC Bi‑directional interface, single‑fiber bi‑di transmission, max 20 km reach
- +3.3 V single power supply, hot‑pluggable, standard SFP footprint compatible with mainstream OLT slots
- Built‑in BPD burst packet detect and RSSI real‑time received‑signal‑strength reporting, optimized for GPON burst timing requirement
- Fully compliant with SFP MSA and SFF‑8472 DDM digital diagnostics;
- Meets Telcordia GR‑468‑CORE reliability requirements;
- ITU‑T G.984.2 B+ / C+ / C++ complete grade support;
- Complete DDM: real‑time monitoring for TX power, laser bias current, RX optical power, module temperature, supply voltage, high/low alarm thresholds configurable.
02｜Three Grades for Different Engineering Deployments
Sopto GPON OLT SFP provides B+, C+, C++ variants for different split‑ratio and link‑loss scenarios:
- B+: Standard PON deployments, widely adopted by global operators;
- C+: Higher transmit output power, supports larger split ratios for long‑reach high‑loss links;
- C++: Ultra‑high output power, dedicated for high‑split‑ratio long‑distance FTTH projects for broader end‑user coverage.
Commercial operating temperature: 0℃ ~ 70℃ for non‑stop data‑center operation. SFF‑8472 DDM allows host devices to read module status directly and simplify link‑fault troubleshooting.
03｜Typical Application Scenarios
- Carrier‑grade GPON OLT equipment for FTTH fiber‑to‑the‑home broadband
