High-performance and highly-integrated optical chips (DBR+MZ) are used to support transmission over 15 km at a rate of 25G.
10G DWDM optical modules support 96 tunable wavelengths, and 25G DWDM optical modules support 48 tunable wavelengths, significantly improving fiber resource utilization and meeting long-term service development requirements.
The pilot tone modulation technology adds low-frequency modulation signals to optical signals to identify channel information. This enables wavelength auto-negotiation between modules, improving the O&M efficiency of wireless networks and reducing OPEX.
