Transition Networks SSDTF10xx-10x series
Devices encode and decode T1 or E1 twisted-pair
copper signals over fiber optic cable to extend the
distance and transmission reliability of high-speed
T1 or E1 data traffic. The device is framing independent (as ESF vs. D4) and supports all
common line codes (e.g., AMI, B8ZS, HDB3).
The SSDTF10xx-10x is designed to be installed in pairs. For example, instal
