Product Code : SCL-EELE-13263
Indian Lab Suppliers supplies the Fibre-Optic trainer for numerical aperture and fibre loss measurement (Product ID: 13263) as part of its electronics engineering lab equipment range. It is a fibre optic trainer for measuring the numerical aperture of PMMA fibre and the loss in 1 m and 5 m patch cords at 660 nm and 850 nm.
Quick Answer
Light from a 660 nm or 850 nm LED (chosen by an SPDT switch) is sent through 1 m or 5 m PMMA patch cords to a phototransistor receiver. The difference in received power between the two lengths gives fibre loss per metre, and the NA jig with its marked scale gives the numerical aperture from the diameter of the light spot at a known distance (NA = sinθ, where tanθ is the spot radius over the distance). A mandrel adds bending loss, and the E/O and O/E characteristics and a simple intensity modulation link complete the set. It runs on 230 V ±10%, 50 Hz mains with fuse and indicator lamp; use an earthed socket.
