 The Product Summary

AOTCascade digital video optical trnsmitter and receiver
adopts international advanced technique bega optical fiber high-speed transmission so that it can ensure the distortionless and high quality transmission of Ethernet on single core or twin-core..AOT Cascade digital OFE uses the complete digital and not-compression technique，the video effect of high quality can satisfy the requirement of user，Each product has passed through strict and integrated quality test process including technique capability test and aging test before sale. We also can customize products to meet special requirement of different users. This equipment weave net method is nimble,can realize stelliform and cascade etc network topological structure, its single wavelength fully can realize 8 - 16 cascade connection methods of node,each other combine with CWDM technology,and can realize the cascade connection transfer of even more nodes.
