With the rapid development of optical communication networks, the application scope of fiber optic patch cords is becoming wider and wider. FTTA duplex patch cords are specially designed for wiring systems in extremely harsh environments. They can resist the erosion of oil or chemicals, have a wide temperature operating range or are rat-proof and waterproof. So what are the common types of FTTA duplex patch cords?
Armored duplex patch cords are more rugged than ordinary fiber optic patch cords. In some harsh environments, ordinary fiber optic patch cords are easily affected by wind, rain, rat bites and low temperatures. After a long period of use, the surface is prone to wear and tear, affecting signal transmission. The armored patch cord is specially designed with a small flexible stainless steel sleeve to protect the optical fiber, and then a flame-retardant PVC coating is added to the outside of the sleeve to achieve moisture-proof and fire-proof functions. Armored fiber optic patch cords can be divided into single-mode and multi-mode, and their connector types are various, including LC, SC, FC, ST, LC/APC, SC/APC, FC/APC, etc.
Armored duplex patch cords are strong in tension and compression, are rat-proof, and are not easily damaged by stepping on. They can also be used in harsh outdoor environments with a lot of dust or prone to rodent damage.
The IP67 FTTA waterproof duplex patch cord complies with the Open Device Vendors Association (ODVA) standard and meets the IP66/67 environmental sealing level. It has a rugged PU jacket and armor for use in high temperatures or harsh environments. Among them, IP (Ingress Protection Rating) refers to the protection ability of optical fiber against solid and liquid particles. The first digit after IP refers to the solid protection level, ranging from 0-6, which indicates protection from large particles to dust; the second digit is the liquid protection level, which indicates protection from vertical water drops to underwater pressure. The larger the number, the higher the liquid protection level. According to the type of connector, IP67 waterproof fiber optic patch cord can be divided into IP67 MPO waterproof fiber optic cable, IP67 LC duplex patch cord, etc. IP67 duplex patch cord has the function of rodent proof, suitable for use in communication towers and CATV (community antenna television), industry, FTTA or other harsh environments to provide protection for the network.
The industrial-grade duplex patch cord is made of SUS spring tube, Kevlar synthetic fiber, braided layer and TPU jacket, which has the advantages of impact resistance, pressure resistance and good flexibility. Its bending resistance, wear resistance, flame retardant and oil resistance also make it very suitable for indoor and outdoor applications, such as industrial environments that require rapid wiring or repeated retraction and use.
Deploying industrial-grade fiber optic patch cords is considered to be a relatively fast and effective solution in industrial environments because it is very suitable for emergency communications, radio and television, emergency rescue through fiber optic communications, mining and other outdoor applications that avoid moisture, chemicals and corrosive gases.
CPRI patch cords are standard sizes for duplex LC connectors and can be used for fiber-to-the-antenna (FTTA) connections for current 4G/LTE, 5G networks, as well as base station structures connecting AAU and RRU, and are also suitable for horizontal and vertical wiring structures in indoor and outdoor environments. CPRI patch cords have a low-smoke, halogen-free jacket that protects against UV and chemical corrosion, making them ideal for harsh outdoor environments. And the hard armored tube of the FTTA CPRI patch cord makes it more stable and has higher tensile strength. These FTTA CPRI patch cords have excellent compressive strength and good flexibility. They are designed for extremely harsh outdoor environment applications, with high reliability and reduced long-term operation and maintenance costs.
