As gigabit optical network construction, large-scale 5G deployment, and "Dual-Gigabit" city initiatives accelerate globally, fiber access networks are undergoing a massive migration from GPON/EPON to 10G PON, with continued evolution toward next-generation 50G PON. With deep expertise in PON (Passive Optical Network) optoelectronic devices, JH Optoelectronic delivers full-chain PON optical modules and components spanning OLT central office, ODN optical distribution network, and ONU/ONT customer premises — covering GPON, EPON, XG-PON, XGS-PON, NG-PON2, and 25G/50G PON across all technology generations. Our solutions empower carriers worldwide across diverse access scenarios including FTTH, FTTB, FTTC, FTTP/POL, and 5G xHaul backhaul.
▲ End-to-End PON Architecture: OLT Central Office → ODN Optical Distribution → ONU/ONT Customer Premises
The OLT serves as the aggregation and control hub of the PON network, deployed in the carrier's central office (CO). It connects upstream to the IP metro or backbone network via uplink ports. JH Optoelectronic provides a comprehensive portfolio of OLT-side optical modules, including GPON OLT Class B+/C+/C++, XGS-PON OLT N1/N2/E1/E2 grades, and Combo PON (GPON+XGS-PON integrated) modules. These support up to 1:128 split ratios and 60 km extended reach, enabling carriers to achieve smooth multi-generational coexistence on a single fiber network.
The ODN (Optical Distribution Network) consists of feeder fiber, passive optical splitters (PLC Splitter), and distribution fiber — entirely free of active electronics, dramatically reducing operational costs. ONUs/ONTs are deployed at customer premises. JH Optoelectronic provides GPON ONU, XGS-PON ONU Stick/SFP form-factor modules, and BOSA/Triplexer optical sub-assemblies supporting bridge, router, and gateway modes. For FTTR (Fiber to the Room) in-home networking, we also offer compact, embedded ONT module solutions.
For residential broadband subscribers, JH provides GPON/XGS-PON ONU optical modules and SFU/HGU terminals supporting gigabit/10G broadband, 4K/8K IPTV video, VoIP, and smart home services. Combo PON solutions enable seamless in-service upgrade from GPON to XGS-PON without ODN infrastructure changes.
For high-density multi-dwelling units (MDU) and apartment buildings, fiber reaches the building basement or hallway, with MDU-type ONUs or reverse-powered DPUs (Distribution Point Units) completing the last tens of meters over existing VDSL2/G.fast copper. A single MDU ONU serves 24-48 households, balancing coverage and investment efficiency.
Passive Optical LAN replaces traditional 3-tier Ethernet switching with PON technology for enterprise campuses, schools, hospitals, and hotels. ONUs are deployed directly in offices, classrooms, and wards. With zero active electronics in the distribution layer, TCO is reduced by over 40% and cabling space requirements drop by 80%.
Leveraging existing PON fiber infrastructure for 5G small cell and indoor distributed antenna system (DAS) fronthaul and midhaul transport, 25G/50G PON optical modules support eCPRI/ORAN interfaces. WDM-PON solutions with wavelength multiplexing carry both residential broadband and 5G backhaul on a single fiber, maximizing fiber asset utilization.
PON technology covers a 20-60 km radius on a single fiber, paired with up to 1:64 split ratios — the optimal choice for universal service obligations in rural and underserved areas. XGS-PON Long-Reach Class E2 modules support 60 km transmission without repeaters, connecting scattered villages cost-effectively.
For whole-home gigabit Wi-Fi coverage in large apartments, villas, and premium residences, FTTR extends fiber into every room, replacing wireless Mesh Wi-Fi backhaul. JH provides compact, embedded ONT modules with discreet, invisible fiber deployment for seamless gigabit wireless experience throughout the home.
GPON/EPON → XG-PON/XGS-PON → NG-PON2 → 25G/50G PON full product portfolio, with a single platform compatible across multiple PON generations, protecting carriers' existing investments
Combo PON (GPON+XGS-PON integrated) optical modules with built-in WDM multiplexer simultaneously carry GPON and XGS-PON services over the same ODN, enabling non-disruptive migration to 10G PON without ODN replacement
GPON OLT Class C++ modules support 60 km logical reach; XGS-PON OLT E2 grade modules deliver 32 dB+ link budget to meet long-reach coverage requirements in remote areas
Supports up to 1:128 split ratio per PON port, serving 128 subscribers simultaneously — dramatically reducing per-subscriber access cost and improving network buildout economics
ONU Stick SFP/SFP+ modules plug directly into CPE or switch SFP cages, eliminating standalone ONU devices. QSFP-DD form-factor 50G PON modules meet OLT high-density port requirements
Modules fully interoperable with Huawei, ZTE, FiberHome, Nokia, and other mainstream OLT/ONU equipment vendors. Telcordia GR-468 reliability certified with MTBF exceeding 500,000 hours
