EORPR in Metro Optical Ethernet Solution - 2

June 16, 2021

The traditional Ethernet uses a "best effort" transmission mechanism, which can well adapt to the sudden transmission requirements of data services and has good scalability; the disadvantage is that there is no QOS guarantee and the protection switching capability is poor. SDH equipment has a protection switching time of less than 50ms, and has good QOS performance, but SDH uses voice-oriented. TDM transmission mode is not efficient when transmitting data services. EORPR combines the economics of Gigabit Ethernet, SDH has the advantages of strict guarantee for delay and jitter, reliable clock and 50ms ring protection and recovery. The RPR network is a ring structure composed of packet switching nodes, and adjacent nodes are connected by a pair of optical fibers. The links between nodes are based on optical fiber and can be expanded using WDM.

There are many GPON Devices under GL-COM. GPON ONT also known as GPON ONU series products include GPON VOIP ONT, GPON CATV ONT, GPON 4GE ONT, GPON 1GE ONT, etc.
