SVT-1000 SERIES
Optical Cable Sheave Testing Machine
UNIVER SVT-1000 Optical Cable Sheave Testing Machine is designed to determine the ability of the optical ground wire (OPGW) , optical attached cable (OPAC) or All-Dielectric Self-Supporting (ADSS) Fiber Optic Cable to withstand bending around rollers or bows during installation, when a specified load is applied, the optical cables could become excessively deformed. The optical unit(s) could also be damaged and the optic fibers adversely affected.
Knowledge
Standard/Testing Method: IEC 60794-1-21 E18B, IEEE 1222 (ADSS), IEEE 1138 (OPGW)

Acceptance criteria
Any cracks or breaks of any of the cable components shall constitute failure. This assessment is made with the naked eye.
Attenuation increases across the loop-backed spliced fibers shall be normalized to decibels/kilometer; this provides an average increase across all the loop-back spliced fibers. Any permanent increase in optical attenuation exceeding a value of 1.0 dB/km at 1550 nm for single mode and 1300 nm for multimode shall constitute failure.
Typical Applications
Attenuation or cracks after cyclic bending around rollers
Attenuation or cracks after cyclic bending around rollers
