2.5 / 5 GBPS FULL-DUPLEX 70/80 GHZ PTP LINK

SensorTec’s break-through improvement of ST-EB Series wireless systems provide the ultimate Gigabit backbone capacity for most bandwidth-hungry applications for carriers and enterprises. The products operate in 70/80 GHz licensed bands and have different antenna options for various link distance requirements.EB Plus links now can carry 2.5 Gbps of Full-Duplex traffic each direction for a total of 5 Gbps, highest link capacity offered by any wireless PTP link to date at any frequency band. Through the use of an OMT coupler, one EB PLUS link can carry 5 Gbps full-duplex (10 Gbps aggregate) for ultra-high-capacity backbone applications.
The huge data-carrying capacity of EB Plus links allows transparent CPRI traffic transport up to 2.4576 Gbps as well as OBSAI traffic up Short Range Version to 1.536 Gbps. This allows carriers to carry large capacity LTE traffic with 1ft Antenna within the framework of the CPRI / OBSAI protocol environment.
As a true Layer 1 link, the link operates like a fiber optic link with the lowest latency possible. At ~50 nanoseconds, the latency through the link is negligibly small compared even with fiber optic cable and is perfected suited for applications that demand an instant transfer of packets such as financial transactions.
