Then what is the delay of OTN network?<\/p>\n\n\n\n<p>An OTN network is a communication system that uses <a href=\"https:\/\/www.fibermall.com\/blog\/wdm-otn-transmission-technology.htm\" target=\"_blank\" rel=\"noreferrer noopener\">OTN (Optical Transport Network)<\/a> devices as the network equipment and optical fiber as the transmission medium. The latency of an OTN network is the amount of time it takes for data to be transmitted from the OTN device at the sending end to the OTN device at the receiving end.<\/p>\n\n\n\n<p>Like general-purpose communication systems, the latency of an OTN network consists of three components: transmission delay, propagation&nbsp;delay, and processing&nbsp;delay.<\/p>\n\n\n\n<p>Below is a typical OTN network system composition and delay distribution diagram.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-system-composition-and-delay-distribution-1024x483.png\" alt=\"OTN network system composition and delay distribution\" class=\"wp-image-6286\" style=\"width:800px\" width=\"800\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-system-composition-and-delay-distribution-1024x483.png 1024w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-system-composition-and-delay-distribution-300x141.png 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-system-composition-and-delay-distribution-768x362.png 768w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-system-composition-and-delay-distribution.png 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-transmission-delay\"><span class=\"ez-toc-section\" id=\"Transmission_Delay\"><\/span><strong>Transmission Delay<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The transmission delay is the time it takes for the raw data to enter the transmitting end of the OTN device at the transmitting end, to be sent out from the transmitting end, and until it is completely in the line fiber.<\/p>\n\n\n\n<p>The raw data undergoes the following two main processing flows at the sending end of OTN equipment before the data can be sent to the line fiber for transmission.<\/p>\n\n\n\n<p>1. Through the truck &#8211; OTU (Optical Transponder Unit) converted to OTN equipment can be transmitted to the data. OTU to process the data spent on the instantaneous delay of the order of 10\u03bcs ~ 100\u03bcs.<\/p>\n\n\n\n<p>2. Through the checkpoint&nbsp;&#8211; WDM&nbsp;achieves a fiber-combined transmission of multiple data optical signals. The instantaneous delay time spent by the combining\/splitting unit to process the data is in the order of ns.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-propagation-delay\"><span class=\"ez-toc-section\" id=\"Propagation_Delay\"><\/span><strong>Propagation Delay<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Propagation delay is the time it takes for data to be sent from the sending OTN device to be received by the receiving OTN device. The data sent from the sending OTN device is mainly transmitted via optical fiber. The delay of optical fiber is of the order of 5\u03bcs\/km.<\/p>\n\n\n\n<p>Since optical signals in optical fibers may cause dispersion effects, dispersion compensation modules may be needed to compensate for the problems caused by dispersion. Therefore, the propagation delay must also include the transmission delay caused by the dispersion compensation modules.<\/p>\n\n\n\n<p>When the transmission distance is long, repeaters (i.e., optical amplification units) need to be added along the OTN network to regenerate and amplify the optical signals before continuing to transmit. From the above analysis, we can see that the propagation delay is affected by optical fibers, dispersion compensation modules, and optical amplification units.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-processing-delay\"><span class=\"ez-toc-section\" id=\"Processing_Delay\"><\/span><strong>Processing Delay <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The size of the processing delay depends on the \u201creceiving OTN device\u201d. From the above \u201cOTN network system composition and delay distribution diagram\u201d, we can see that the data processing process of the receiving <a href=\"https:\/\/www.fibermall.com\/store-17089-optical-transport-network.htm\" target=\"_blank\" rel=\"noreferrer noopener\">OTN device<\/a> is exactly the reverse process of the data processing of the sending OTN device.<\/p>\n\n\n\n<p>Through the checkpoint (multiplexing\/demultiplexing unit), the multiplexed data optical signal in the optical fiber is restored to a single-channel data optical signal.<\/p>\n\n\n\n<p>Through the truck (OTU unit), the single-channel data optical signal is converted into original data. Therefore, we can assume that the processing delay is the same as the transmission delay, mainly affected by the optical forwarding unit OTU and the multiplexing\/demultiplexing unit.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-delay-components-and-factors.png\" alt=\"OTN network delay components and factors\" class=\"wp-image-6287\" style=\"width:800px\" width=\"800\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-delay-components-and-factors.png 690w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/OTN-network-delay-components-and-factors-300x201.png 300w\" sizes=\"(max-width: 690px) 100vw, 690px\" \/><\/figure>\n\n\n\n<p>Therefore, we can see that the OTN network delay is mainly affected by the transmission link (such as optical fiber) and physical devices (such as OTU unit, multiplexing\/demultiplexing unit, and optical amplification unit).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-reduce-the-delay-of-otn-network\"><span class=\"ez-toc-section\" id=\"How_to_Reduce_the_Delay_of_OTN_Network\"><\/span><strong>How to Reduce the Delay of OTN Network? <\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>As we know, 5G network requires ultra-low delay, and even the end-to-end delay of the whole network is required to be as low as 1ms. OTN network, as an important bearer network of 5G network, generally starts from the two factors of transmission link and physical device analyzed above to reduce the delay in order to meet the ultra-low delay requirement of 5G network.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-method-01-optimize-transmission-link\"><span class=\"ez-toc-section\" id=\"Method_01_Optimize_transmission_link\"><\/span><strong>Method 01 Optimize transmission link<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Use a minimalist network architecture design, reduce intermediate forwarding nodes, reduce intermediate optical amplification units, construct a single-hop&nbsp;network, and reduce transmission delay. Use coherent optical communication technology, which does not need dispersion compensation modules, and can eliminate the additional transmission delay introduced by dispersion compensation modules.<\/p>\n\n\n\n<p>Coherent optical communication does not mean that the transmission light is coherent light communication, and any optical communication system uses laser.
