As 5G deployments scale up, fixed broadband accelerates, and enterprise leased-line bandwidth demands surge, metro and backbone networks face unprecedented capacity pressure. Leveraging deep expertise in DWDM (Dense Wavelength Division Multiplexing), ROADM (Reconfigurable Optical Add-Drop Multiplexer), and coherent optical communications, JH Optoelectronic delivers full-scenario optical transport solutions spanning metro access, aggregation, and backbone core layers. Our portfolio includes EDFA optical amplifiers, WSS wavelength selective switches, MCS multi-carrier switches, OPM optical performance monitors, OLP optical line protection, and 400G/800G coherent pluggable transceivers—empowering carriers to build high-bandwidth, highly reliable, and flexibly reconfigurable next-generation all-optical networks.
▲ End-to-End Metro Network Solution Topology
The core layer adopts OTN (Optical Transport Network) architecture, leveraging DWDM technology to achieve ultra-high capacity transmission with 96+ wavelengths per fiber. Supporting both C-band (4.8 THz) and C+L-band (9.6 THz) extensions, per-wavelength rates continue to evolve from 100G toward 400G and 800G. JH Optoelectronic provides complete EDFA arrays, ROADM nodes, and coherent transceivers to meet the ultra-long-haul transmission requirements of cross-province and international backbone networks.
The aggregation layer handles regional traffic aggregation and forwarding, while the access layer connects end devices such as base stations, enterprise customers, and residential broadband terminals. JH Optoelectronic offers 10G/25G/50G PAM4 transceivers for 5G fronthaul and midhaul requirements, and 100G/200G coherent modules for aggregation-to-core uplinks, with FlexE (Flexible Ethernet) slicing technology enabling hard isolation across multiple services.
25G/50G PAM4 BiDi and CWDM/DWDM transceivers meet the 25 Gbps eCPRI interface requirements for 5G fronthaul; 100G/200G QSFP28 coherent modules bridge DU-to-CU midhaul links, with single-fiber bidirectional operation saving 50% fiber resources.
Metro core layer adopts 400G/800G coherent DWDM solutions supporting 400G QPSK/16QAM per wavelength with transmission reach exceeding 2,000 km; aggregation layer 100G/200G coherent solutions cover metro spans of 80–600 km.
C+L-band EDFA arrays combined with Raman Fiber Amplifiers (RFA) enable regeneration-free ultra-long-haul transmission; flexible-grid ROADM supports per-wavelength add/drop and pass-through, building all-optical cross-connect (OXC) backbone nodes.
400G ZR/ZR+ coherent pluggable transceivers embed directly into routers and switches, enabling IP-over-DWDM connectivity between data centers over 100–500 km, eliminating standalone optical transport equipment and reducing TCO by over 40%.
MS-OTN (Multi-Service OTN) platforms unify SDH/PDH, Ethernet, SAN storage, and OTN services, with ODUk flexible cross-connect enabling rapid service provisioning and manageable end-to-end latency.
OLP 1+1/1:N optical line protection and OTDR fiber monitoring deliver sub-50 ms fast protection switching; OPM optical performance monitoring collects real-time OSNR, optical power, and key metrics to build AI-driven predictive optical network operations.
