This manual provides basic instructions for the use of EXFO OTDR series Optical Time Domain Reflectometers, including the setup of the device, measurement of optical cables, analysis of measurement results and generation of reports. No part of this publication may be reproduced, stored in a retrieval system or transmitted in any form, be it electronically, mechanically, or by any other means such as photocopying, recording or otherwise, without the prior writt eved to be accurate and reliable. Introducing the FTB-700 OTDR The FTB-700 OTDR allows you to characterize a fiber-optic span, usually optical fiber sections joined by splices and connectors. The MaxTester 700B/C Series is the first tablet-inspired OTDR line that is handy, lightweight and rugged enough for any outside plant environment. With a 7-inch, outdoor-enhanced touchscreen–the most efficient handheld display in the industry–it delivers an unprecedented user experience. To ensure quality of service (QoS), network constructors, service providers and operators need to accurately pinpoint existing and potential problems, making test and measurement equipment vital.

The OPM1315 uses a standard 9V battery which will normally yield approximately 200 hours of continuous operation. An optical power meter (OPM) is a device used to measure the power in an optical signal. Measuring optical power level changes, to determine fiberoptic switching times or to observe transient fluctuations from fiber movement or network reconfiguration, goes beyond the design of most fiberoptic power meters. to electrical domain using optical-to-electrical (O-E) converters and high-speed oscilloscopes. This unit is designed to fit the hand comfortably, and can be used for installation, debugging, and maintenance of any fiber.

OTN defines a precise layered structure for transporting and managing data: Optical Payload Unit (OPU): Holds the client signal and ensures transparent mapping. Optical Data Unit (ODU): Adds overhead for performance monitoring, multiplexing, and protection. Function diagram 200 Gbit/s transponder/muxponder, aggregating 4x40 Gbit/s and 4x10 Gbit/s into a single 200 Gbit/s /OTU2C standard OTN trunk. Key technologies supported include 3G, 4G/LTE, IMS, Ethernet, OTN, FTTx, and various optical technologies (accounting for an estimated 35% of the portable fiber-optic test market). EXFO has a staff of approxim ately 1600 people in 25 countries, supporting more than 2000 telecom customers worldwide. In-depth coverage of DWDM, OTN, coherent optics, network design, and more — written by field engineers. Glossaries, troubleshooting guides, optical formulas, 80+ infographics, and ITU-T standards references. The diagram titled "The multiple layers of the OTN network" clearly illustrates how the various layers within the OTN framework work together to ensure smooth transport of different client signals, including Ethernet, Fiber Channel, MPLS/IP, and SDH/SONET.
