摘要
随着传统固话业务的萎缩和宽带通信业务的日益丰富,传统宽带ADSL的发展受到各种瓶颈的限制。相比于目前宽带接入中的G.652光纤,G.657光纤具有与G.652 D光纤类似的性能参数,比G.652B光纤的要求更严格,但具有更小的弯曲半径(15 mm),其将在宽带接入中得到广泛的应用。
With the atrophy of fixed telephone service and the rapid development of broadband communications service, the development of conventional broadband ADSL is subject to the limitation of various bottlenecks. Compared to the G. 632 fiber currently used for broadband access, G. 657 fiber allows smaller bending radius of 15 mm while having similar performance with G. 652 D fiber, so its wide use for broadband access will be expected.
