1) Overview
MDR-8000 digital microwave equipment can transmit DS1, DS1(E), DS3, OC3 standard in frequency bandwidth of 2~11GHz. Customers may choose frequency and channel capacity. In particular, it is highly suitable for improving the performance of the KT’s small capacity digital microwave equipment (MDR-6702) ; it can transmit DS3 and OC3 standard with large capacities by comparison to the existing MDR-6702; and can load 4 sets (1+1 Hot-Standby standard) onto standard ETSI 7ft rack due to its compact size. |
