Intelligent Highway All-Optical Communication Solution

As highway services evolve, roadside communication networks need to change too. But how?

The increasing number of video monitoring sites being deployed along roadways, allied to the switch from Standard Definition (SD) to High Definition (HD) videos, means that highway bandwidth needs are now much higher. But the security of core services on communication networks — such as digital toll collection — can never be compromised. And, with heavy usage as traffic flows swell, fiber faults need to be easier to locate, to cut down maintenance costs. What's to be done?

Huawei's All-Optical Communication Network Solution effectively addresses such challenges, delivering high bandwidth, with Optical Transport Network (OTN) devices at the transmission layer fully compatible with existing Synchronous Digital Hierarchy (SDH) devices, ensuring smooth bandwidth expansion and evolution without the need to modify existing underlying fiber infrastructure. In addition, the solution provides any number of nodes at 10G to 100G — often expressed as N x (10G to 100G) — easily covering the bandwidth needs of highway services.

The solution also delivers the high security and reliability that's now non-negotiable, using the hard pipe technology to provide physical isolation, ensuring that toll collection, monitoring, and office services are securely transmitted over a single network. And on the roadside access network, the hand-in-hand ring network formed by industrial Optical Network Units (ONUs) provides End to End (E2E) dual-link protection against network storms and multi-point failures, delivering highly reliable access.

Plus, the solution simplifies Operations and Maintenance (O&M), with a built-in intelligent fiber diagnosis board enabling minute-level fault demarcation and meter-level fault locating, slashing onsite maintenance times by as much as 90%.
