Hi let’s talking about important side for installation Telecom Tower or might be problem happening sometime it’s problem in VSWR( voltage stande wave Ratio ) as we know it’s measuring the reflection for wave through Cables to Antenna for several parts through it for that how we can find the part cause in case so we need make a check for 1. Measure the VSWR at different points along the transmission line to identify the problem area. 2. Inspect the antenna for physical damage and ensure proper installation. 3. Check the transmission line for any issues, such as kinks, bends, or loose connections. 4. Determine the source of the VSWR problem, whether it's the antenna, the matching network, or the transmitter. 5. Perform antenna tuning or replace faulty components as needed. 6. Verify the system performance after making any adjustments or replacements. Troubleshooting VSWR issues in telecom towers requires a systematic approach and the expertise of skilled RF engineers or technicians. By following these steps, you can efficiently identify and resolve VSWR problems to ensure optimal performance of your telecom infrastructure.

**🚀 DWDM Troubleshooting Tips for Telecom and Network Engineers 🚀** In a DWDM system, troubleshooting can be daunting. But don't fret! Here's a handy guide to help you diagnose and fix those pesky issues: 1️⃣ **Perform a Loopback Test:** Use an optical attenuator to loopback devices to avoid port damage from high power. You can also use software loopbacks via the NMS. 2️⃣ **Reset the Line Cards:** You can reset cards in two ways: * Warm reset (no impact on service) * Cold reset (service impact) Reset via NMS, physically removing and re-inserting the card, or using the reset button on the control board. 3️⃣ **Check Alarm History:** * History alarms (alarms previously detected, logged, and cleared) * Current alarms (still active, awaiting resolution) 4️⃣ **Review Performance Monitoring Logs:** Check metrics like bit errors, availability, power levels, OSNR, etc., on line cards or the optical transport manager. 5️⃣ **Use an OTDR:** Determine attenuation, calculate power, and identify events. 6️⃣ **Employ a Spectrum Analyzer and Power Meter:** Analyze optical power and wavelengths. 7️⃣ **Inspect Line Card LEDs:** Cards have LEDs that indicate line card hardware status, service status, software status, and more. 8️⃣ **Physically Examine Fiber:** Check fiber patch cables, attenuation levels, connectors, splice points, SFP modules, and more. 🌟 Remember, troubleshooting is a skill that improves with practice! 🌟 **#DWDM #Troubleshooting #OpticalTransportNetwork #NetworkEngineering #FiberOptics** Got any other troubleshooting tips?

Troubleshooting Principles Most specialists manage troubleshooting for any incident or problem using their historical experiences. Actually, some of them spend the majority of their time not adhering to the fundamentals of their diagnostics and troubleshooting. For instance, numerous serious issues require a long time to settle since one principle was ignored (external before internal). #Huawei concluded these steps (Old Topic) since I don't see that with any other vendor, as briefly arranged as follows: 1: External Before Internal (Outside Subrack Before Inside Subrack: Line Fiber Before Internal Logical Fiber) 2: Network before a single site. 3-Higher-Severity Before Lower-Severity Alarms (Critical before Minor) 4: Multi-Wavelength Before Single-Wavelength Signals (MUT_LOSS Before CHAN_LOSS) 5: Bidirectional before unidirectional links. 6: Common Before Isolated Issues (Issue on Subrack before on a Single Board). For all telecom engineers, it is simply preferable to use the Huawei poster attached in the below image for inspection, analysis, and fault diagnosis in the upcoming incidents.
