Huawei has some module supports long-haul transmission,including CXP、CFP、CFP2 and QSFP28 module.
Long-Haul Transmission:100G
Huawei 100G CFP module supports a 5000 km transmission distance without electrical regeneration, equivalent to that supported by MSA modules. It is the industry's only mature pluggable 100G module for commercial use in backbone networks, and will become the mainstream for 100G application.
Long-Haul Transmission:200G/400G
The current 200G evolution primarily aims to improve transmission performance. MSA modules have better performance than CFP modules and are continuously optimized to meet ultra-long haul transmission requirements. However, CFP modules have lower power consumption and higher integration, which can meet medium- and long-haul transmission requirements.
By the way, you can check the price of HUAWEI CXP-100G-SR10 and HUAWEI CFP-100G-LR4.
