Comparison between Standard OTDR and In-Service OTDR 📡 Standard OTDR (Optical Time Domain Reflectometer) Purpose: Used for testing and characterizing fiber optic cables when the fiber is not in use (i.e., no live traffic). Key Features: ·      Sends a high-powered light pulse into the fiber and measures reflections and backscatter. ·      Identifies faults, splices, bends, and fiber length. ·      Requires the fiber to be disconnected from service. ·      Ideal for installation, commissioning, and maintenance. Limitations: Cannot be used on live fibers carrying traffic. Risk of service interruption if used on active links.   🔄 In-Service OTDR (Live OTDR or Out-of-Band OTDR) Purpose: Allows testing of fiber optic cables while they are in service, without interrupting traffic. Key Features: ·      Uses a separate wavelength (typically out-of-band, like 1650 nm) that does not interfere with data transmission. ·      Often used with WDM (Wavelength Division Multiplexing) systems. ·      Enables continuous monitoring and fault detection on live networks. ·      Useful for proactive maintenance and troubleshooting. Limitations: Requires special filters (WDM couplers) to separate test signals from traffic. Slightly more complex setup and higher cost.

𝟴 𝗤&𝗔 𝗲𝘅𝗽𝗹𝗮𝗶𝗻 𝗢𝗽𝘁𝗶𝗰𝗮𝗹 𝗽𝗼𝘄𝗲𝗿 𝗖𝗼𝗺𝗺𝗶𝘀𝘀𝗶𝗼𝗻 𝗶𝗻 𝗗𝗪𝗗𝗠 1- What is power commission in dwdm ? Simply its a process where we set / calculate / determine the optical power value of the Tx ports to meet the Rx requirements 2- What should we consider in power commission process ? We need to consider the Rx sensitivity , Rx overload , launched power range , attenuation 3- Do we need some tools for this process ? Of course we may need to ensure fiber is clean . Also we may need to add FOA , VOA . We need also tools like power meter and spectrum analyzer ( OSA ) 4- what is FOA , VOA uses for ? FOA is the fixed optical attenuator VOA is the variable optical attenuator Both provides attenuation value ( fixed or controlled ) to help us adjust optical power of the link 5- do we have to align the spectrum analyzer and how ? Yes we need to align spectrum analyzer to ensure accuracy of values . First ser the optical power value of any output port then measure the same port using spectrum analyzer and compare the values . Differences should not exceed 0.5 dB 6- what is overload ? This represents the maximum receiving power value of a port 7- what’s Rx sensitivity ? Its the minimum detectable power received by a port 8- what’s launched power range ? This represents the range of transmitted optical power that could provided by the card Next post will explain the next part for how to calculate the power values To see all posts and knowledge of Transmission : https://lnkd.in/daAQCEd
