Benefits of technology

This technology allows for flexible allocation of different types of light signals based on their specific needs. Its technical effect includes reducing costly equipment purchases while also improving efficiency by allowing multiple devices with similar capabilities to be used together more efficiently.

Problems solved by technology

Technologies have developed over recent years for improving communication systems like Passed Tunneling MultiProtocol Overpass Transport Partners (PTCPoE Group Layer Connection Point Switches - UTP) and Intermediate Access Control Interface Express Frquency Routers (IFO routers)-WDPIMS(Flexible Distributed Additive Module) technologies called Different Time Division Multiple Functions (DTSF)). These techniques aim to provide efficient data switching capabilities while also allowing for reconfiguration within certain times during operation.

specific Embodiment

[0052] like image 3 System architecture for 100 GHz wavelength channel spacing shown. In this solution, both the upstream and downstream channels of the OLT side and the ONU side use tunable lasers to achieve different wavelength outputs, which can realize variable wavelength control on the OLT side, variable wavelength control on the ONU side, and variable wavelength control at both ends. The modulator can realize high-speed signal transmission. image 3 Adjustable lasers are used at both ends of the OLT and ONU to achieve variable wavelength control, and the uplink and downlink signals can use C-band or S-band. In the downlink direction, by adjusting the Tunable Laser, the tunable laser optical module 301, which integrates single-fiber bidirectional transceivers, outputs a specific wavelength λd1 (d downlink wavelength, which is the S-band), and 32 301 outputs λd1...λd1+32 are different 32 wavelengths, 32 different wavelengths are transmitted to 10km ~ 80km optical fiber ...
