Future Proof 8 Channel DWDM Box Supports 100GHz or 200GHz Grid Spacing‌

1. Ultra-Long-Haul Transmission: 2000km Relay-Free Transmission‌

The 8CH DWDM MUX employs advanced optical amplification technology and dispersion compensation modules to achieve relay-free transmission over a single span of 2000 km. By leveraging the synergistic effect of EDFA (Erbium-Doped Fiber Amplifier) and Raman amplification, it effectively overcomes fiber attenuation limitations, reducing relay equipment costs by 60% compared to conventional solutions. With a 100GHz/200GHz channel spacing (ITU-T G.694.1 standard), it significantly suppresses nonlinear effects, ensuring signal integrity over long distances. This feature is particularly suitable for submarine cables, remote backbone networks, and other scenarios, reducing operational costs by over 45%.

3. 5G Fronthaul/Backhaul: Sub-μs Low Latency‌

To meet 5G URLLC (Ultra-Reliable Low-Latency Communication) requirements, the 8CH DWDM MUX achieves sub-μs processing latency through hardware bypass design. Its single-fiber bidirectional (BiDi) architecture reduces fiber usage by 50%, aligning with 5G fronthaul 25G/50G eCPRI standards. In backhaul scenarios, it supports FlexE (Flexible Ethernet) slicing for service isolation and dynamic bandwidth allocation, catering to mMTC (massive Machine-Type Communication) requirements.

4. Multi-Protocol Support: SDH/SONET & OTN Compatibility‌

The device integrates an intelligent protocol conversion module, seamlessly supporting legacy protocols such as SDH (STM-64/256) and OTN (ODU0-3). With GMPLS control plane integration, it enables automatic wavelength provisioning, ensuring smooth upgrades for existing transport networks. Testing confirms a bit error rate (BER) of ≤1E-12 for GE/10GE/40GE Ethernet services, meeting high-reliability demands in finance, government, and other critical sectors.

5. Localized Customization: Regional-Specific Solutions‌

Tailored solutions for different environments include:

• Southeast Asia‌: IP67-rated version for high-temperature, high-humidity conditions
• Middle East Desert‌: Enhanced heat dissipation (operating temp. up to 85℃)
• Western China‌: Cold-resistant version (-40℃ startup) for oilfield monitoring networks
• Rural Africa‌: Solar-powered variant for off-grid deployments
• European Data Centers‌: Compact 1/2U module for high-density installations
