A slight degradation that\u2019s harmless at 1 Gbps can cause errors at 25 or 100 Gbps.<\/li>\n<li><strong>Environmental Factors<\/strong>: Modules in AV racks often operate under less ideal conditions than in data centres.

They offer sufficient bandwidth for HD and 4K video, but require attention:<\/p>\n<ul>\n<li>Ensure proper cooling in your racks.<\/li>\n<li>When in doubt, choose industrial-grade modules, especially in warm or dusty environments.<\/li>\n<li>Monitor temperature and transmit power using DDM (Digital Diagnostic Monitoring) \/ DOM (Digital Optical Monitoring).<\/li>\n<li>Consider preventive replacement after 5 years of intensive use.<\/li>\n<\/ul>\n<p>QSFP28 (100G) modules are increasingly used in AV over IP, particularly in large production environments and the broadcast industry. These modules operate at the edge of thermal and reliability limits \u2013 extra monitoring and redundancy are crucial here.<\/p>\n    <\/div>\n        <div id=\"topic5\" class=\"skip-item\">\n                        <h2>Conclusion<\/h2>\n                <p>Not all fiber modules are created equal. Choosing the right type \u2013 and the right quality level \u2013 helps determine how long your AV network will remain reliable. In the next blogs, we\u2019ll dive deeper into how fiber modules wear out and what you can do to slow down that process.<\/p>\n    <\/div>\n        <div id=\"topic6\" class=\"skip-item\">\n                        <h2>More information<\/h2>\n                <p>Visit our website to see the AV Solutions.<\/p>\n<div class=\"hs-cta-embed hs-cta-simple-placeholder hs-cta-embed-207665517270\" style=\"max-width: 100%; max-height: 100%; width: 260px; height: 50.390625px;\" data-hubspot-wrapper-cta-id=\"207665517270\"><a href=\"https:\/\/cta-na2.hubspot.com\/web-interactives\/public\/v1\/track\/redirect?encryptedPayload=AVxigLJmwXrklZNG3x3dQ7tAAZQIgIsg1shDInvQ9VBbiHiZoCynUV94JMwOO0IxN3gIBFfSMSqx%2B6JTye6vQ0e3VWJvBOXvIOG8DLOj5CfIo65QGp3rxJtB4xP5%2BPKW8bYLWwhu%2F4g7Hlj8lPIBaJNHla0nSXV98AA3eiK4vTzTig%2FRyzOvY4%2F6ZA%3D%3D&amp;webInteractiveContentId=207665517270&amp;portalId=242128791\" target=\"_blank\" rel=\"noopener\"><br \/>\n<img decoding=\"async\" style=\"height: 100%; width: 100%; object-fit: fill;\" src=\"https:\/\/hubspot-no-cache-na2-prod.s3.amazonaws.com\/cta\/default\/242128791\/interactive-207665517270.png\" alt=\"NETGEAR AV SOLUTIONS\" \/><br \/>\n<\/a><\/div>\n<p>&nbsp;<\/p>\n<p>Discover everything you need to know about AVoIP and building an AV network.<\/p>\n<div class=\"hs-cta-embed hs-cta-simple-placeholder hs-cta-embed-207830330055\" style=\"max-width: 100%; max-height: 100%; width: 260px; height: 50.390625px;\" data-hubspot-wrapper-cta-id=\"207830330055\"><a href=\"https:\/\/cta-na2.hubspot.com\/web-interactives\/public\/v1\/track\/redirect?encryptedPayload=AVxigLKSEFYKgJJTOMNvVAoTPHd9IwVGVWcxfJGIQzPKPmf3kqu5eqnYdhOP3e5kL1JoHsd%2FyIg6PADR9eEN3LCOpzskNKTQ6xIB5bNNW7QLlQC0pKsNClFStn2fDSomLhGnkVYux9PpTd713XZ6AmvHA3Wog%2FezB50jMyKhiI08wVaPg%2B03H%2F3yJ0UKF15vzGWg94QPxEnqQzVW0v8tuA%3D%3D&amp;webInteractiveContentId=207830330055&amp;portalId=242128791\" target=\"_blank\" rel=\"noopener\"><br \/>\n<img decoding=\"async\" style=\"height: 100%; width: 100%; object-fit: fill;\" src=\"https:\/\/hubspot-no-cache-na2-prod.s3.amazonaws.com\/cta\/default\/242128791\/interactive-207830330055.png\" alt=\"NETGEAR ACADEMY\" \/><br \/>\n<\/a><\/div>\n<p>&nbsp;<\/p>\n<p>Get free support for your AV project from our senior AV engineers.<\/p>\n<div class=\"hs-cta-embed hs-cta-simple-placeholder hs-cta-embed-207818050288\" style=\"max-width: 100%; max-height: 100%; width: 260px; height: 50.390625px;\" data-hubspot-wrapper-cta-id=\"207818050288\"><a href=\"https:\/\/cta-na2.hubspot.com\/web-interactives\/public\/v1\/track\/redirect?encryptedPayload=AVxigLKUcC7MvFJO38VFkiikPrbyTi5ziTD%2Bsks5hEF1CRkcAePeUZNCMs%2BsBP%2BY2U8cIT6tXv8JO55NBtLFe5AvfK30eFWc8x4uOUwan7MJfWKfbfF%2Fo6GHhRW%2B%2FENwGGjwZ5X%2BGqgoCBr6jvU04ZU%2B%2BqjEyic3pTh3hqhAUxB83SOOu05SEvjHa478erXywJDlsVXn4vGGotZKwRqtiUQ7uIDz1coFhLDV%2FqvOaJWao10aLECzKW9LdQ%3D%3D&amp;webInteractiveContentId=207818050288&amp;portalId=242128791\" target=\"_blank\" rel=\"noopener\"><br \/>\n<img decoding=\"async\" style=\"height: 100%; width: 100%; object-fit: fill;\" src=\"https:\/\/hubspot-no-cache-na2-prod.s3.amazonaws.com\/cta\/default\/242128791\/interactive-207818050288.png\" alt=\"CONTACT PROAV DESIGN\" \/><br \/>\n<\/a><\/div>\n\n\t\t\t<div\n\t\t\tclass=\"hs-form-frame\"\n\t\t\tdata-region=\"na2\"\n\t\t\tdata-form-id=\"de76be58-5099-46f2-9aa1-e0c67296e48a\"\n\t\t\tdata-portal-id=\"242128791\"\n\t\t\t >\n\t\t\t<\/div>\n\t\t\t\n    <\/div>\n    \n","protected":false},"excerpt":{"rendered":"","protected":false},"author":121,"featured_media":22370,"parent":6754,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"templates\/blog-wifi.php","meta":{"_acf_changed":false,"content-type":"","_price":"","_stock":"","_tribe_ticket_header":"","_tribe_default_ticket_provider":"","_tribe_ticket_capacity":"0","_ticket_start_date":"","_ticket_end_date":"","_tribe_ticket_show_description":"","_tribe_ticket_show_not_going":false,"_tribe_ticket_use_global_stock":"","_tribe_ticket_global_stock_level":"","_global_stock_mode":"","_global_stock_cap":"","_tribe_rsvp_for_event":"","_tribe_ticket_going_count":"","_tribe_ticket_not_going_count":"","_tribe_tickets_list":"[]","_tribe_ticket_has_attendee_info_fields":false,"footnotes":"","_tec_slr_enabled":"","_tec_slr_layout":""},"class_list":["post-21329","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What types of fiber modules exist, and how do they differ in wear sensitivity?
