The polarization-maintaining fiber cables are offered as Ø 900 µm buffer in black, or a Ø 3 mm cable in black with Kevlar strain-relief. For each fiber end the fiber connectors can be selected from a wide range of connector types (FC, AVIM (compatible with LSA), E2000) with. This Specification covers the design requirements and performance standard for the supply of optical fibre cable in the industry. ARTIC ensures a stable quality control system for our cable products through several programs including ISO 9001, ISO 14001 and ROHS. Typical extinction ratios between 18 – 25dB maintain input. ast right-hand digit when considering the specification limits. This method is in accordance with the rounding method of ASTM Practice E29 (Standard Practice for using significant diPANDA Polarization Maintaining (PM) fibers are designed with high performance properties including excellent birefringence and low attenuation. NA is specified by the fiber manufacturer. Additionally the effective numerical NAe 2 is measured for each fiber batch by Schäfter+Kirchhoff. Cut-off wavelengths range from 360 nm to.
