fiber optic cable is to finish each optical fiber with a connector so it can plug into equipment such as a transceiver, a patch panel or another cable. In the field there are three ways to do it: fusion splice a factory-made pigtail onto the fiber, install a mechanical fast connector, or glue a connector on with epoxy and polish the end face by hand. Most single-mode field terminations use a spliced pigtail or a splice-on connector, while multimode fiber is often terminated directly.<sup><a href=\"#ref-1\">[1]<\/a><\/sup><\/p><p>Below, a table compares the three methods on loss, time and tools, followed by the steps and checkpoints for each and the tests that prove a termination is good.

A splice makes a permanent joint between two fibers.<sup><a href=\"#ref-1\">[1]<\/a><\/sup> When installers talk about fiber optic cable termination, they usually mean the first: fitting a connector to the end of a glass fiber, either directly or by splicing on a short fiber that already has one.<\/p><p>Either way, the result is judged on the same two numbers. Insertion loss is the light loss where two connectors mate, and return loss, the inverse of reflectance, measures how much light reflects back toward the source.

Fusion splicing adds a splicer and splice protectors; fast connectors need only the connector maker&#8217;s assembly tool; epoxy and polish adds adhesive, a curing oven for heat-cured epoxy, polishing film and a microscope. Acceptance testing needs an optical loss test set, plus a power meter to confirm a fiber is dark before inspection, and an OTDR where the project specifies one.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-1291\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"2\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-1291\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\">  Is it hard to terminate fiber optic cable? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-minus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-plus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" role=\"region\" aria-labelledby=\"e-n-accordion-item-1291\" class=\"elementor-element elementor-element-18fd5bf e-flex e-con-boxed e-con e-child\" data-id=\"18fd5bf\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-800e3f6 elementor-widget elementor-widget-text-editor\" data-id=\"800e3f6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Mechanical fast connectors are the easiest to learn, but results still depend on a good cleave and clean fiber.
