MobileAccess™ 1000/1200 Chapter 4. 4.1 Appendices Appendices Appendix I: Optical Test Procedure This section describes the methods applied to test fiber optic cable’s optical insertion loss and return loss. 4.1.1 Fiber Optic Cable Test Due to the extended distances that analog signal transmissions travel on cable, the major challenge is to determine the status of the cable. In order to determine that the cables are functioning, technical personnel need to perform optical power tests.
Appendices MobileAccess™ 1000/1200 Following the completion of the insertion loss test, the return loss test determines the optical signal power that returns to the laser. The return power affects the laser, changing the laser’s base current. 4.1.
MobileAccess™ 1000/1200 4.1.4.2 Appendices Method #2: Single Point Test Connection description: This method assumes that there are two parallel fibers on the path to be tested. Connect fiber jumper at end of the cable being tested to another parallel cable. Connect the light source, optical power meter and optical jumper as shown in Figure 4-2. This measurement can test two cables simultaneously. Light source Fiber optic jumper Optical power meter Connector Figure 4-2: Single Point Test 1.
Appendices 4.1.6 MobileAccess™ 1000/1200 Optical Return Loss Measurement Test Connection description: Connect a light source and optical power to the inputs. If the coupler has one output, connect the tested cable to this output. If the coupler has two outputs make a pigtail at the second output. Light source Optical power meter 1 IN OUT 3 2 4 Cable Being Tested Optical Coupler "Optical Terminator" (pigtail) Figure 4-3: Optical Return Loss Measurement 4.1.7 Measurement Procedure 4.1.7.
MobileAccess™ 1000/1200 Appendices To isolate cable: 1. Find place near test point where winding the cable into a pigtail is possible. 1. Make pigtail. 2. If cable is shorter than 100 meter, then verify that cable is disconnected at end. 3. Measure the return light power (P2), connector #2. Calculating Return Loss Calculate the difference between the signals in dB. (Return loss)dB = (P2)dBm – (P3)dBm + (Lc)dB 4.1.
Appendices 4.2 MobileAccess™ 1000/1200 Appendix II: Link Measurements Form To smoothly carry out link measurements, refer to table Table 4-1: Fiber optic Cable Test Results. This table aids system evaluation and provides necessary feedback to MobileAccess. The following issues should be taken into account: • Measure the optical power for every link with an optical meter and light source, according to the number of links or RHU’s. • Measure the typical signal strength (RSSI) for every installed antenna.
4.3 Frequently Asked Questions 1. What optical parameters are recommended in order for the MobileAccess network to operate with the highest performance? Answer. Three parameters are specified for every installation: • Single-mode Fiber: Corning SMF 28 or equivalent • Back Reflection: Less than 45 dB of back reflection @1310 nm • Loss: Total end to end optical loss should be less than 1.5 dB @1310 nm 2.
Appendices MobileAccess™ 1000/1200 Answer. We have found that only the APC polish can offer consistently low levels of back reflection with a high level of reliability. There are connectors on the market with UPC, SPC and PC polishes that specify low back reflection. The problem with these various polishes is that they are very fragile. A small particle or even environmental changes can cause dramatic changes in the optical performance.
MobileAccess™ 1000/1200 Appendices Answer. As stated above, the APC polished connector is the most robust and reliable solution and is the only recommendation of MobileAccess. However existing backbone with UPC polished connectors could be used if they were tested and found to have less than -45 dB back reflection and less than 0.5 dB loss per mated pair connection. Again, the end to end performance of each fiber link should meet or exceed the MobileAccess specifications.
