Fiber optic pigtail are utilized to terminate fiber optic cables via fusion or mechanical splicing. High-quality pigtail cables, coupled with correct fusion splicing practices offer the best performance possible for fiber optic cable terminations. Fiber optic pigtails are usually found in fiber optic management equipment like ODF, fiber terminal box and distribution box.OM4 has a suggested jacket color of aqua. It is a further improvement to OM3. It too uses a 50?m core, but it supports 10 Gigabit Ethernet at lengths up 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters. Laser optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs.UPC connectors are polished with no angle. UPC connectors are not exactly flat, however; they have a slight curvature for better core alignment. Another more obvious difference is color. UPC connectors are blue while APC connectors are green.Strippable Tight Buffer
A buffer where the gap is not visible under 100 power magnification, no interstitial material defined as loose powder or liquid is used, and at least 10 cm of material can be removed with one circular cut.
