美国国家标准与技术研究所（NIST）研制了一种双向时间传输装置，它利用SONET（SDH）系统开销中任何当前未使用的字节来实现时间传输。该硬件显示出稳定性，允许在短距离（km）上进行时间传输，其稳定性小于10 ps。需要光纤中额外放大器的距离上的时间传输尚未被研究，相同水平的精度也应该是可能的。
The National Institute of Standards and Technology (NIST) has built a two-way time-transfer device which uses any currently unused byte in the SONET (SDH) overhead to effect time transfer, The hardware shows stability which allows time transfer over short distances (km) with stabilities less than 10 ps. Time transfer over distances that require additional amplifiers in the fiber have not yet been investigated, Accuracy at the same level should also be possible.
