Genuine Huawei GPON-OLT-CLASS C++ Optical Transceiver 38J0-6537E-C++ SFP Module 34060841 Huawei GPON OLT Class C++ Ultra-High Power Budget Optical Transceiver Module (Part Number / BOM: 34060841) is engineered for Optical Line Terminal (OLT) devices in Gigabit Passive Optical Networks (GPON). Built in a hot-pluggable SFP form factor and fully complying with the ITU-T G.984.2 standard, this module is an upgraded tier designed to go beyond Class C+ specifications. It supports asymmetric data rates of 2.488 Gbps downstream and 1.244 Gbps upstream via single-fiber bi-directional (BIDI) transmission. Featuring an even higher optical link budget of approximately 35 dB and supporting a high split ratio of 1:128 or higher, it provides a significantly enhanced optical power profile to conquer severe fiber attenuation and ultra-long distance requirements.

Typical Applications
Carrier-Grade FTTH / FTTB / FTTO Access
- Ideally engineered for large-scale residential areas, commercial parks, and industrial zones requiring high-density optical access architectures. It installs directly into the GPON service boards of Huawei OLT platforms to bridge central office lines with residential or commercial ONU/ONT devices.
Central Office (CO) Access Layer
- Deployed within carrier Central Offices as a critical high-power hardware bridge, reliably connecting massive end-user aggregates to the core network backbone across broadband infrastructures.
Long-Reach Passive Optical Networks
- Specifically optimized for long-distance deployments, complex terrains, or multi-stage splitting scenarios that suffer from severe optical signal attenuation, providing premium line stability where standard modules fail.
Product Highlights
1.Extreme Reach & Coverage
- Features an ultra-high 35 dB optical budget with +6 dBm to +10 dBm Tx power, effortlessly overcoming severe signal attenuation caused by complex terrains or multi-stage splitters to ensure pristine long-distance connectivity.
2.High-Density, Low-Cost Access
- Reliably drives a high split ratio of 1:128 and beyond, maximizing ONU/ONT aggregation per PON port. This significantly reduces OLT chassis footprint and backbone fiber usage, drastically lowering cost-per-user.
3.Plug-and-Play for Hassle-Free O&M
- Standard SFP form factor with native Huawei firmware completely eliminates link drops, alarms, or generic compatibility issues. Integrated real-time DDM allows administrators to remotely monitor optical telemetry for faster troubleshooting.
4.Green & Energy-Efficient Design
- Utilizes advanced burst-mode transmission and a low-power-consumption profile to minimize data center energy costs, while strictly adhering to Class 1 Laser safety regulations for an eco-friendly and safe operation.
