OFT-CWDM Series

The Precision Rated Optics OFT-CWDM-LB OTDR packs the features expected in a hand held OTDR and more. It is available in a variety of wavelengths with up to four wavelengths per unit. The Standard units are 1471/1491/1511/1531nm and 1551/ 1571/1591/1611nm. Other wavelengths combinations are available upon request.Use the light source in CW mode with the onboard broadband power meter with selectable wavelengths. This OTDR is fast, easy to use, affordable and rugged. It boast a short dead zone, bright 4” color display and with an onboard context sensitive help system the OTDR has a minimal learning curve for all users. The PRO-CWDM weighs in at less then 2.0 pounds with a hardened water resistant enclosure, this OTDR is great for all conditions. The rubber boot with bail will add protection and provides the ideal angle for viewing the display while operating on a work bench.
