The Black Box MT661A-SM is a managed media converter designed to extend T1/E1 copper interfaces over singlemode fiber optic cable. This unit converts T1/E1 signals from standard RJ45 connectors to 1300nm singlemode fiber, enabling reliable data transmission over distances up to 28 kilometers. It's engineered for environments where existing copper infrastructure is insufficient for required distances, such as connecting separate buildings on a campus or extending network reach in large industrial facilities.
This converter is compatible with standard T1 (1.544 Mbps) and E1 (2.048 Mbps) interfaces. It functions as a transparent bridge, meaning it passes all T1/E1 framing and signaling without modification. It is designed to interoperate with other T1/E1 fiber optic converters supporting 1300nm singlemode transmission. For managed operation, it supports SNMP and a web-based interface for configuration and monitoring.
Requires standard T1/E1 cabling on the copper side and SC connectors for the singlemode fiber interface. Power is supplied via an external AC adapter (included). The unit is designed for desktop or rackmount installation using an optional rackmount chassis. Ensure proper fiber optic cleaning procedures are followed during installation to maintain signal integrity.
