Typical Applications
10G PON Upgrades & New-Build Projects
- Purpose-built for next-generation 10G PON expansion and greenfield optical deployments. It installs directly into the Combo service line cards (such as CSHF or CSHD) of Huawei MA5800 series multi-service OLT platforms, empowering tier-1 telecom operators and ISPs with a future-proof, seamless migration path to 10G XGS-PON.
Operator Backbone & Metro Access Networks
- Deployed within carrier Central Offices (CO) and metropolitan access layers as a critical high-capacity hardware bridge, reliably aggregating and connecting massive end-user data streams to the core backbone network across broadband infrastructures.
Large-Scale Campus & Enterprise 10G FTTH / FTTB / FTTO
- Ideally engineered for high-density, ultra-high-bandwidth single-fiber deployments in smart enterprise campuses, commercial buildings, and industrial zones to satisfy demanding Gigabit-plus dedicated line and commercial cloud service requirements.
Hybrid Environments with Legacy ONU Compatibility
- Tailored for complex, multi-generation hybrid optical network architectures. Leveraging its dual-mode capabilities, it enables a single PON port to serve both next-generation 10G premium subscribers and traditional, legacy GPON ONU/ONT devices concurrently, eliminating the need to overhaul existing passive fiber infrastructure while maximizing ROI.
Product Highlights
1.Class D Advanced Reach & Attenuation Tolerance
- Delivers an elite, industry-standard Class D optical link budget (35 dB+), outperforming standard Class C+ by approximately 3 dB. This heavy-duty optical gain margin effortlessly conquers severe line attenuation caused by complex terrains or multi-point connection drops, ensuring pristine signal integrity over extreme distances.
2.Seamless Network Evolution via BiDi WDM
- Utilizes built-in Wavelength Division Multiplexing (WDM) to concurrent handle next-gen XGS-PON and legacy GPON signals over a single fiber core. It avoids costly, time-consuming overhauls of existing passive ODN infrastructures (cables, splitters, closures), allowing a seamless and instant upgrade to 10G services.
3.Ultra-High Split Ratios to Maximize ROI
- Reliably drives high-density split ratios of 1:128 and up to 1:256 per PON port. By aggregating massive residential or commercial ONU/ONT terminals onto a single port, it drastically minimizes OLT chassis footprint and backbone fiber consumption, lowering the overall cost-per-user.
4.100% Huawei Native Reliability & O&M
- Authentic factory-authorized hardware with pre-integrated native firmware guarantees optimum packet-forwarding metrics and seamless interaction with Huawei network management software. It completely eliminates link drops, false alarms, or recognition glitches common with generic third-party modules.
