Oscilloquartz Debuts New Rubidium Access Device for LTE-A Networks

0

Oscilloquartz, an ADVA Optical Networking company, has launched the newest member of its OSA 5410 series – the OSA 5411.

This new product is the first access network device in the industry to offer Rubidium-based timing and synchronization capabilities along with a unique holdover algorithm.

This technology breakthrough will enable much longer frequency and phase holdover in case of GNSS outages. The OSA 5411, and the wider OSA 5410 series, also support the latest ITU-T G.8275.1 standard. Both of these factors are critical for the successful migration to LTE-Advanced (LTE-A) and LTE-TDD networks.

“The OSA 5411 represents a triumph for our team, for our technology. Introducing Rubidium with an advanced holdover algorithm into the access network is no small task and the implications will be profound,” said Gil Biran, general manager, Oscilloquartz. “The OSA 5411 is essentially a toolbox for Mobile Network Operators (MNOs). It’s at once a mini-grandmaster clock, a boundary clock, a slave device, a sync probe – it can be whatever the operator needs. This level of flexibility is phenomenal, especially for timing and synchronization devices. The product’s release marks a first for the industry. At this year’s WSTS, we’re going to showcase the full potential of the OSA 5411 with a hands-on demonstration. We can’t wait to reveal what it’s capable of.”

The OSA 5411 features the latest Syncjack™ technology and has been engineered to be flexible and robust, enabling the highest synchronization delivery, monitoring and assurance possible. It includes dual field replaceable power supplies that ensure continuous operation and protects services against unwanted outages.

The OSA 5411’s capability to be either a grandmaster clock, a boundary clock, a slave device or a sync probe presents MNOs with a highly capable 1U timing and synchronization unit. With the product’s support of the ITU-T G.8275.1 and G.8265.1 PTP telecom profiles, MNOs can actually push the grandmaster functionality much closer to the access network.

By doing this, MNOs don’t need to upgrade the entire core network as they migrate to LTE-A or LTE-TDD but only the access network. This functionality could have profound budgetary implications.
