PA4 – for cables terminated with two or four fiber optic connectors, metal spring tube 3.0 mm made of stainless steel covers and protects fanouts at their whole length from the furcation point to the connector, providing 2000 N crush resistance.
Fibrain cross-connect drop cable patchcords are specifically designed to be used in FTTH networks, between a customer outlet and an ONT equipment. Fibrain patchcords are strengthened, thus they are resistant to mechanical damages, contrary to ordinary patchcords. Therefore, each cable is constructed from flame-retardant materials, which do not emit any poisonous substances and toxic smoke (LSOH). Depending on a number of terminated fibers and a cable, the connector is clamped directly on the cable’s sheath or performed as a short fanout. PA4 – for cables terminated with two or four fiber optic connectors, metal spring tube 3.0 mm made of stainless steel covers and protects fanouts at their whole length from the furcation point to the connector, providing 2000 N crush resistance.
Each type of single-mode fiber has its own area of application, and the evolution of these optical fiber specifications reflects the evolution of transmission system technology from the earliest installation of single-mode optical fiber to the present day. Choose the right fiber is very important for each project/installation. The OS2 G.657 standard single-mode fibers were developed to allow a better bending radius regarding the G.652 standard. For the OS2 G.657 fiber there are 4 subcategories: G.657.A1, G.657.A2, G.657.B2, G.657.B3. The G.657.A1 fiber type is characterized by 10 mm minimum bending radius. These specifications of the G.657 fibers allow to have a better cost-efficiency due to compact cable designs and reduced space requirements.
LC FO Connector is a small form factor fiber optic connector that uses a 1,25mm ceramic ferrule to align and connect optical fibers. Used in high-speed communication networks.Provides low insertion loss and high return loss. The connector is easy to install and provides a secure and reliable connection for both single-mode and multimode fiber optic cables. Its compact size makes it ideal for applications where space is limited, such as data centers, telecommunication rooms, and fiber-to-the-home installations.
PC (Physical Contact), is a type of polishing procedure that makes flat surfacein the ferrule end face. The optical return loss of PC connectors is >-40dB. PC connectors may only be mated with other PC or UPC connectors. It can be identified by the blue boot and is used in single-mode and multi-mode fibers. This polishing procedure is outdated and is replaced by UPC.
