        Extend critical T1 and E1 communications beyond the limitations of copper cabling while gaining greater network visibility and reliability. These managed media converters transport T1/E1 traffic over single-mode fiber, enabling organizations to maintain dependable voice, data, and legacy communication services across long distances without sacrificing performance.

        Designed for service providers, utilities, transportation systems, government agencies, industrial facilities, and enterprise networks, these converters extend T1/E1 circuits up to 28 km over fiber. By replacing vulnerable copper segments with fiber infrastructure, organizations can reduce exposure to electromagnetic interference, improve signal integrity, and support communications between remote offices, network facilities, substations, control centers, and distributed infrastructure.

        Integrated management capabilities provide operational visibility that helps simplify troubleshooting and improve network uptime. Administrators can monitor connections, quickly identify issues, and maintain critical services more efficiently across distributed environments. Available with either SC or ST fiber interfaces and North American or universal power supply options, these converters provide deployment flexibility while supporting global network requirements.

        Ideal for extending business-critical T1/E1 applications, these solutions help organizations improve network resilience, reduce maintenance challenges, and preserve investments in existing T1/E1 infrastructure while benefiting from the performance advantages of fiber connectivity.
