The unsung hero solving this crisis isn&#8217;t a massive router or a miles-long cable; it&#8217;s a tiny, powerful component called a <strong>coherent optical transceiver<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For anyone involved in <strong>data center interconnects (DCI)<\/strong>, <strong>metro networks<\/strong>, or <strong>long-haul transmission<\/strong>, understanding this technology is no longer optional\u2014it&#8217;s essential.
