Once a fiber optic cable plant, network, system or link is installed, it needs to be tested for four reasons: to insure the fiber optic cable plant was properly installed to specified industry standards. to insure the equipment intended for use on the cable plant will operate properly on the cabling to insure the communications equipment is working to specifications to document the cable plant and network for reference in case of future problems Tools and Test Equipment Needed The following tools are needed to test and troubleshoot the fiber optic cable plant, system or link properly. Optical Loss Test Set or power meter and test source with optical ratings matching the specifications of the installed system and proper connector adapters. An OLTS that merely tests cable plant loss may not include a calibrated power meter needed for testing transmitter and receiver power, so a calibrated power meter and source are a better choice for link or system testing. Reference test cables with proper sized fiber and connectors and compatible mating adapters of known good quality. These do not generally need to be “reference quality” but only in good condition, generally defined as having connector losses of less than 0.5 dB. Visual fiber tracer and/or visual fault locator Connector inspection microscope with magnification of 100-200X and fixturing for proper connectors. Video microscopes are recommended. e. Cleaning supplies intended specifically for the cleaning of fiber optic connectors, The Optional: OTDR with long launch and receive cables 3. Testing And Troubleshooting the Installed Cable Plant All fiber cable plants require certain basic tests to insure they were installed correctly and meet expected performance values. These are guidelines for testing and troubleshooting the cable plant itself. The most valuable data one can have for troubleshooting is the installation

...NT1310 Codi Roebuck Unit 10 Lab 1 01/04/2016 Professor: Ronald j. wojcik Fiber optics for diagnostics and troubleshooting are used in varying capacities to test, measure, analyze, transmit, distribute, and/or simulate an optical signal with which the technician can perform procedures and processes associated with maintenance, problem solving, and calibration of equipment and/or networks. Normally in these applications, fiber optic products are used to create loop tests or transmit signals from point-to-point (either single-point to single-point, or single-point to multiple-points). For loop testing, commonly referred to as loopback testing, a signal is sent from a piece of equipment through a loopback or cable and returned to the source, simulating a complete network connection. This type of test allows technicians to perform function tests and internal diagnostic processes without the equipment being physically tied to an active network. This type of setup provides technicians with the advantage of easily isolating individual components for faster, more comprehensive analysis. With signal transmission applications, technicians generally use cables (multiple types for different applications) to connect one or more pieces of...

Build on the trainer the hydraulic circuit shown in the figure below, using the components listed here. hydraulic power unit (2) pressure gauges flow control valve (FCV) – simulated load flow-meter Page 1 of 2 2. Initial setup: a. Fully close (CW) the FCV, and fully open (CCW) the pressure relief valve on the power unit. b. Start the power unit, and slowly adjust the pressure relief valve until pressure gauge P1 reaches 50 bar. Let the unit run for a few minutes then check and adjust P1 if necessary. c. Do not touch the pressure relief valve for the remainder of the lab. d. Fully open the FCV. 3. Test: a. Record the pressures P1, P2 and the flow rate under the “Min.” column in the table below. b. Slowly turn the FCV CW, adding a simulated load to the system. When the pressure at P1 increases to 15 bar, stop and record pressure P2 and the flow rate. c. Repeat for all columns listed in the table. The final column, listed as “Max Pres.” should be run with the FCV fully closed. Note the sound of the power unit during this test. You should detect changes in tone as the load (pressure) is increased. P1 Pressure (bar) P2 (bar) Flow Rate (lpm) Min * 15 20 25 30 35 40 45 46 47 48 49 Max.

If a student is absent, a note must be presented to his/her teacher when the student returns to class. This note must have information i.e. phone number, contact person and reason for absence. 2. Lateness – Lateness will be taken very seriously and will affect a student’s grade. Students are expected to come to class on time. If you come to class late you must sign the late log and provide the reason for your lateness (i.e. late pass) GRADING POLICY Every student has the right to see how their grade is calculated. In order to discuss individual grade calculations you can set up an appointment during your teacher’s office hours. Your science teacher will explain the grading policy during this meeting. Your child’s grades will also be available for you to view on line through a program called Pupil Path, www.Pupilpath.com Your child will receive the instructions and passwords for this within the first week of school. • Class participation –Class participation covers every aspect of a student’s behavior in the classroom. This includes the questions you ask, the comments you make, the notes you take, completion of class work, notebook check, presenting your reference tables and your prompt arrival to class.

There are 1000 (m in one mm.. etc.) To convert from one metric unit to a different metric unit (a different prefix): 1. First, decide how many places to move the decimal point (the number of 0’s in the chart above indicates the number of places to move the decimal point). 2. Next you need to decide whether to move the decimal point left or right. To decide this, think about which is the smaller unit. (The smaller the unit is, the more of them you need to get the same amount. e.g. pennies vs. dollars) NOTE: Here is another way to write the conversions, using distance (the meter is the basic unit for distance) as an example: 0.001 km = 1 m = 10 dm = 100 cm = 1000 mm = 1,000,000 (m = 1,000,000,000 nm The “staircase” method: One more way to remember about sliding decimal points when converting between prefixes in the metric system! [pic] Move the decimal point 3 places for every step you move on the “staircase”, and in the same direction traveled on the staircase (left vs. right). Unfortunately, you can see that the “c” prefix...
