对LTE(长期演进)时代下的POTN(分组光传送网)技术进行了探讨。伴随着LTE时代的到来,从CAT4[指UE(用户设备)的Category4]到CAT6,还有未来的CAT8,传送网的好坏起到关键性的作用,因此LTE对传送网的要求也是日益提高,而运营商要想实现多业务发展,也需要更好的传送网,POTN作为未来的光传送网演进趋势,能够更加适应于更快速、更大容量的LTE时代。
The POTN (Packet Optical Transport Network) technology under the LTE (Long Term Evolution) era is discussed. With the advent of the LTE era, from CAT4 [UE4 (Category 4) to CAT6] and CAT 8 in the future, the quality of the transport network plays a crucial role. As a result, the requirements of the transport network for LTE are also increasing , And operators want to achieve multi-service development, but also need a better transport network, POTN as the future evolution of optical transport network, can be more adapted to the faster, more capacity of the LTE era.
