1.1 ± 0.1m long, 900µ OD loose blue color hytrel tubing jacketed, 5/125µ 850nm Panda PM fiber patchcord terminated with an ultra FC/UPC connector on one end which is pre-aligned and locked to PM slow axis and an 8.0° ± 0.5 degrees angle polished 1.8mm OD D-Shaped glass ferrule on the other end. ER is minimum 25dB (on best effort basis) measured one way only, using FC/APC connector as input. SP1: The fiber itself is 250µ OD buffered. The hytrel tubing will be fixed (UV epoxied) onto fiber (fiber with acrylate buffer) at 15mm ± 2mm distance from the glass ferrule polished endface tip. PM fiber slow axis is aligned visually parallel to the glass ferrule flat within ± 3 degrees.
