Lentronics TN1Ue

Overview

The Lentronics™ TN1Ue SDH Multiplexer delivers optical networking solutions for critical communications and provides transport and access capabilities for voice, data, IP/Ethernet WAN, video and utility teleprotection traffic in a single package. It supports high-speed fibre optic communications at STM-1, STM-4 and STM-16 and provides advanced network visibility from the SDH level down to individual 64 kb/s signals. The optional CDAX module provides an integrated digital cross-connect for grooming 64 kb/s channels and optimizing tributary payloads. The modular design supports add/drop multiplexer topologies and allows capacity expansion by replacing optical transceiver modules. It includes redundant common equipment for path switched ring and ring architectures, built-in test capabilities, and delivers 99.999% system availability per ITU-T standards with fast path protection switching of <3 ms. The unit is utility-hardened to meet IEC 61850-3 and to operate reliably from -4°F to +140°F (-20°C to +60°C) and meets Earthquake Risk Zone 4 shock and vibration specification. A special metal cage enclosure satisfies ETSI EMC requirements. Security features include segregated and dedicated SDH payload assignments, and port and VLAN partitioning to isolate critical communications applications. VistaNET network management software provides complete system monitoring and diagnostics. Recommended related products and services listed include Ether-1000 Unit, Cyber Secured Service Unit, and TTMX Teleprotection Terminal. The TN1Ue is intended to transport voice, data, IP/Ethernet WAN, video and utility teleprotection traffic in critical communications environments. Its support for STM-1, STM-4 and STM-16 interfaces, add/drop topologies, and SDH-level visibility supports network capacity expansion and 64 kb/s channel grooming. It is described as an ideal optical networking solution for electric power utility, transportation, pipeline and many industrial requirements and is hardened for substation operation by meeting IEC 61850-3. Path switched ring architectures with redundant common equipment provide high availability and fast path protection switching of <3 ms for critical services.
