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.The LC connectors are highly popular within single mode networks. It is known for good performance and small size. LC connectors have a 1.25mm ferrule, approximately half the size of SC connectors. It?s also commonly referred to as the little connector. The LC connector is a small form factor (SFF) connector, which is designed to join LC fibers where a connection or disconnection is required.Single-mode fiber provides users with a greater transmission rate in addition to nearly 50 times longer distance as opposed to multi-mode fiber. However, single-mode fiber is more expensive than multi-mode fiber. Among all the differences between single-mode and multi-mode fibers, the most basic is the size difference in the fibers? core as well as the associated loss or attenuation and fiber bandwidth. G.657A1 is the NEW de facto standard for bend-insensitive NDSF SMF for premises cabling, thanks to optimized performance and cost balance. Minimum bending radii can be optimized, but this sacrifices fiber attenuation and cost. ITU-T G.657A1 and A2 are fully compliant with G.652D, and can offer enhanced, low-loss fiber. Bend-insensitive NDSF is defined in ITU-T G.657, with different minimum bending radii characteristics: G.657A1 (10 ?m).
When weighing your options between on-premises and access network fiber replacement or new installation, we highly recommend replacing legacy OS1 with a new bend-insensitive OS2 (ITU-T G.657A1) SMF cabling system to support longer reach with enhanced link performance.Some applications are more sensitive to return loss than others; they call for APC connectors. For example, in higher optical wavelength ranges (above 1500 nanometers) like those used for RF video signals, reflected light can adversely impact the signal. That is why we see APC connectors being used by most cable companies and other FTTX providers in outside plant applications.
APC connectors are also commonly used in passive optical applications (both GPONs and passive optical LANs) due to the fact that many of these systems also use RF signals to deliver video. Future higher-speed passive optical networks and other WDM applications that will use higher wavelengths via singlemode fiber will also likely require the reduced return loss of APC connectors. UPC connectors are blue while APC connectors are green.Tight buffer
Tight-buffered construction uses 900?m buffered fibers. The core is protected by two-layer coating. The first is plastic and the second is waterproof acrylate. The core of the cable is never at risk of exposure, unlike the loose-buffered cable which can escape its confines. Fibers are surrounded by dielectric strength members (FRP) and are protected by a rugged polyurethane outer jacket and provides superior environmental and mechanical protection. The fiber count for tight-buffered fiber cable varies from 1 to 144 fibers, but generally cables with 2, 6, 12, 24 fibers are most commonly used. Larger fiber counts such as 48 fibers, 96 fibers and 144 fibers are also available for specific applications.
