G optical module km
G optical modules, such as 100G and 400G transceivers, support transmission distances ranging from a few hundred meters to over 80 kilometers depending on type and fiber used.
Transmission Distance Categories
- Short Range (SR/VR): Typically used for intra-data center connections. For example, 400G SR4.2 modules can reach up to 150 meters on OM4 multimode fiber and 100 meters on OM3 fiber, using parallel transmission and PAM4 modulation for high bandwidth within data centers .
- Medium to Long Range (FR/LR/ER): Single-mode fiber modules extend reach significantly. FR modules can reach up to 2 km, LR modules up to 10 km, and ER modules up to 40 km, suitable for campus, metro, or regional networks .
- Ultra-Long Range (ZR): Some 100G ZR4 modules can operate over 80 km or more, often requiring coherent modulation and sometimes dispersion compensation, making them ideal for telecom backbone or long-haul networks .
Factors Affecting Reach
- Fiber Type: Multimode fiber (MMF) supports shorter distances (up to 150 m for 400G SR4.2), while single-mode fiber (SMF) supports longer distances (2 km to 80+ km).
- Modulation Technique: PAM4 is commonly used in 400G modules to double data rate per channel, while NRZ is used in some 100G modules .
- Amplification and Dispersion Compensation: Unamplified modules may be limited to 5–10 km, whereas modules with EDFA or dispersion compensation can exceed 40–80 km .
- Wavelength and Channels: Modules like QSFP28 ZR4 use multiple wavelengths and lanes to achieve high-speed, long-distance transmission .
Application Scenarios
- Data Centers: Short-range SR/VR modules for high-density, high-bandwidth interconnects.
- Campus/Metro Networks: FR and LR modules for distances up to 10 km.
- Telecom Backbone/Long-Haul: ER and ZR modules for distances from 40 km to 80+ km, supporting high-speed, low-latency links. In summary, the "G optical module km" specification depends on the module type, fiber, and network design, ranging from a few hundred meters for multimode 400G SR modules to over 80 km for single-mode 100G ZR modules with advanced modulation and amplification .
