The Agilent J2127A 10Gb/s Transmission Test Set is a portable instrument for installation and maintenance of high-speed, multi-service transmission networks. It delivers comprehensive test coverage across SONET, SDH, DSn/PDH, and T-Carrier interfaces with optical rates to 10 Gb/s and integrated multi-port Ethernet testing. The instrument reduces test times and operational costs through unified multi-rate, multi-port, and multi-service architecture.
