Singlemode Optical Fiber T-SMF

Teracom Singlemode optical fiber (T-SMF) is designed to provide optimum performance in access and metropolitan access applications. Teracom Singlemode fiber meets the expanded ITU 652 Table C requirements and can be used in loose tube, tight buffered and ribbon cable configurations.

T-SMF with its lower attenuation and PMD is optimized for Access and Enterprise networks, where very high rates of transmission are becoming increasingly more prevalent. T-SMF offers excellent reliability and durability, even in harshest environments.
