solution. 100G-BIDI uses two optical lanes, one for each direction, over a duplex LC multi-mode fiber. 100G-SR1.2 uses four optical lanes, two for each direction, over the same fiber. 100G-BIDI uses NRZ (Non-Return-to-Zero) modulation, which means each bit is encoded as a single symbol. 100G-SR1.2 uses PAM4 (Pulse Amplitude Modulation) modulation, which means each symbol encodes two bits. PAM4 enables higher data rates with lower baud rates, but also introduces more noise and complexity. Both 100G-BIDI and 100G-SR1.2 are compliant to IEEE802.3bm 100GBASE-SR4 standard. The main advantage of 100G-BIDI is that it can reuse the existing 40G-BIDI infrastructure and reduce the fiber cabling cost. The main advantage of 100G-SR1.2 is that it can interoperate with 400G-SR4.2 and provide a future-proof solution for higher bandwidth demand.<\/span><\/p><p><span style=\"font-size: 14pt;\">Another difference between 100G-BIDI (100G-SRBD) and 100G-SR1.2 is the FEC (Forward Error Correction) used. 100G-BIDI (100G-SRBD) modules have been widely deployed for 100G operation over duplex MMF and use a FEC implementation that was developed prior to the IEEE standardization of KP-FEC for 50G PAM-4 based modules. Because of the differences in FEC implementation, 100G-SRBD and 100G-SR1.2 modules are not interoperable with each other.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-57c3e6a7 e-flex e-con-boxed e-con e-parent\" data-id=\"57c3e6a7\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4ed8c274 elementor-widget elementor-widget-heading\" data-id=\"4ed8c274\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">People Also Ask<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-197ca514 elementor-posts--thumbnail-none elementor-grid-3 elementor-grid-tablet-2 elementor-grid-mobile-1 elementor-card-shadow-yes elementor-posts__hover-gradient elementor-widget elementor-widget-posts\" data-id=\"197ca514\" data-element_type=\"widget\" data-settings=\"{&quot;cards_columns&quot;:&quot;3&quot;,&quot;cards_columns_tablet&quot;:&quot;2&quot;,&quot;cards_columns_mobile&quot;:&quot;1&quot;,&quot;cards_row_gap&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:35,&quot;sizes&quot;:[]},&quot;cards_row_gap_tablet&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;cards_row_gap_mobile&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]}}\" data-widget_type=\"posts.cards\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-posts-container elementor-posts elementor-posts--skin-cards elementor-grid\" role=\"list\">\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-20899 post type-post status-publish format-standard has-post-thumbnail hentry category-blog category-wdm-plc-splitter\" role=\"listitem\">\n\t\t\t<div class=\"elementor-post__card\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h3 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/www.fibermall.com\/blog\/ccwdm-vs-cwdm.htm\"  target=\"_blank\">\n\t\t\t\tCCWDM vs CWDM: When Compact CWDM Actually Pays Off\t\t\t<\/a>\n\t\t<\/h3>\n\t\t\t\t<div class=\"elementor-post__excerpt\">\n\t\t\t<p>A CCWDM (Compact CWDM) module performs the same wavelength multiplexing and demultiplexing functions as a conventional CWDM module, but uses a more compact optical architecture.
