XG-PON OLT Class N2a SFP+ Transceiver 20km: 10G-XGPON-SFP-N2a

Our EDGEOPTIC 10G-XGPON-SFP-N2a is multi-vendor compatible XG-PON OLT Class N2a single-fiber SFP+ optical transceiver designed for Optical Line Terminal equipment in high-speed fiber-to-the-home and fiber-to-the-premises network deployments. The 10G-XGPON-SFP-N2a module operates as a bidirectional transceiver utilizing 1577nm wavelength for downstream transmission and 1270nm for upstream reception, enabling full-duplex communication over a single strand of single-mode fiber. Our XG-PON OLT SFP+ transceiver utilizes DFB (Distributed Feedback) laser for transmission and APD (Avalanche Photodiode) for receiving, delivering asymmetric data rates of 9.953 Gbps downstream and 2.488 Gbps upstream as defined by ITU-T G.987.2 XG-PON standard.

The transceiver ensures a 33 dB guaranteed optical link budget, which determines the maximum transmission distance and split ratio capabilities in passive optical network architectures. The Class N2a optical parameters provide robust performance for typical access network deployments with standard splitting configurations. The transmitter optical power ranges from +4 to +8 dBm, while receiver sensitivity reaches -29.5 dBm, supporting distances up to 20 kilometers over standard single-mode fiber infrastructure. However, distance is just indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget, splitter insertion losses, and average attenuation of optical cabling in industry.

10G-XGPON-SFP-N2a compatible XG-PON OLT Class N2a module is hot-pluggable SFP+ with single SC/PC connector as an optical interface, designed specifically for 10G PON port applications. The electrical interface conforms to SFF-8431, SFF-8432, and SFF-8472 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP+ host systems across multiple OLT vendor equipment platforms. Our XG-PON OLT SFP+ transceiver can be encoded to be compatible and successfully operate in different OLT brands including Huawei, ZTE, Nokia, Calix, and other major PON equipment manufacturers. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data are available via MSA-compatible EEPROM interface and enables monitoring of transceiver operational parameters critical for 10G PON network maintenance. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in central office and controlled equipment room environments.

Standards compliance includes ITU-T G.987.2 for XG-PON systems, along with SFP+ MSA mechanical specifications. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility. Our XG-PON OLT Class N2a SFP+ transceiver is CE/RoHS certified, and it is compliant with Class 1 FDA and IEC60825-1 laser safety standards.

Typical applications include next-generation FTTH/FTTP access network deployments, telecommunications service provider 10G PON rollouts, high-bandwidth enterprise fiber distribution, and carrier-class broadband access systems requiring 10 Gigabit downstream capacity. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP+ transceiver EEPROM memory data validation tests.
