ASTEL Bend Insensitive Fiber Optic Patch Cord G.657A1 / G.657A2 is designed for single-mode optical connections in FTTH networks, data centres and fiber distribution installations where limited space and tight cable routing can increase bending-related signal loss. Manufactured using bend-insensitive G.657A1 and G.657A2 optical fibers, the series is suitable for network installations where patch cords may be exposed to microbending. Available with SC, LC, FC, ST and E2000 connector interfaces, the patch cords feature an LSZH (Low Smoke Zero Halogen) cable jacket for professional indoor fiber cabling applications. The series provides typical insertion loss of ≤0.20dB, maximum insertion loss of ≤0.30dB and return loss of ≥55dB for single-mode PC/UPC or ≥60dB for APC connections. Standard lengths range from 0.5m to 100m, with custom lengths from 0.3m to 250m available on request.
Any length from 0.3m to 250m can be provided on request
