St single-mode fiber optic patch cord : commonly used in optical fiber distribution frame, the shell is round, and the fastening way is screw buckle. For 10Base-F connections, connectors are usually ST types. Commonly used in fiber wiring frame. SC-LC single-mode fiber optic patch cord: Different connecting head of fiber patch cord allows it to be more flexible in connection with optical path activities. There are Simplex , Duplex ,Bundle,Ribbon single mode fiber optic patch core. The cable diameter of single mode fiber optic patch cord are 0.
According to cable outer sheath material, it can be divided into ordinary type, ordinary flame retardant type PVC , low smoke halogen free type LZSH , low smoke halogen free flame retardant type, etc. Based on the usage environment: It can divided into the outdoor single mode fiber optic patch cord, indoor single mode fiber patch cord, amoured single mode fiber optic patch cord, waterproof single mode fiber optic patch cord and so on.
The single mode fiber optic patch cord of the Teleweaver Technology uses a unique grinding process, which ensures excellent optical performance and good stability of the product, and ensures long-term safety and reliability of the product. With fiber optic distribution panels, network technicians can control massive fiber cables and connection points in a standard panel or enclosure structure.
Therefore, fiber distribution panels make it simple and convenient for us to do cable management and maintenance. Generally speaking, fiber optic distribution panel can be divided into wall mount and rack mount types.
Wall mount fiber distribution panel are designed for direct termination of fiber optic cables, which can be mounted virtually anywhere. For easy access to cables, wall mount fiber distribution panels are often designed with dual doors. Here takes FS wall mount fiber patch panel video as an example to show how to use and install it in details:.
Rack mount fiber optic distribution panel, on the other hand, is mainly used for data center rack cable management. While the fiber distribution enclosure is a 1U or 2U metal box which provides protections for inside cables. In high density cabling data centers, the rack mount fiber distribution enclosure is much more popular for its larger capacity and versatility. The following video shows how to use a rack mount enclosure :. Fiber patch cables covered with PVC jacket are flexible at normal installation temperatures.
PVC fiber optic patch cord is usually used for indoor applications such as horizontal runs from the wiring center.
While LSZH cable is used in unventilated areas exposed to public, such as subways and tunnels and also used for rooms that are not easy to get out quickly. Aside from these connectors, there is a latest connector design called MDC connector, which enables the highest achievable connector density by delivering a 3X advantage over a standard LC connector. If divided by the criteria whether the connector on each side is the same, they can be divided into same-connector type fiber patch cord and hybrid fiber patch cord.
While hybrid fiber patch cord has different connectors on each end, like fiber patch cord LC to SC. If the port type of devices on both sides are the same, you can choose the same-connector type fiber patch cord, or you need choose the hybrid one. Fiber optic connectors are designed and polished to different shapes to minimize back reflection, which is particularly important in single mode applications. Whereas UPC fiber patch cords apply to optical systems that are less sensitive to insertion loss such as digital TV and telephony.
Fiber patch cord is evolving to keep pace with the ever-increasing bandwidth needs. Some specially designed fiber patch cables emerge to fit different application needs. Knowing the available options would save us significant time and money.
Here are some special fiber optic patch cords for use in certain circumstances. Armored Fiber Patch Cord. Armored fiber patch cord retains all the features of the common fiber patch cord. The main difference between armored fiber patch cable and common fiber patch cord is that armored fiber jumpers are designed with a stainless armored tube inside the jacket and outside the optical fiber as you can see in figure 4.
This design enables armored fiber patch cords strong enough to be anti-rodent and resist the steps by an adult. Strong as it is, the armored fiber patch cord is actually as flexible as standard fiber optic patch cord and can be bent randomly.
Figure 4: Common fiber cable vs armored fiber cord. Bend Insensitive Fiber Patch Cord. Bend insensitive fiber patch cable is highly resistant to bend related damage and loss. It has a small cable bending radius and prevents additional bend losses by innovative core design and enhanced low macro-bending sensitivity. Bend insensitive fiber patch cord is made to support data center and FTTH applications, and high-density cabling that has to wrap and take tight corners.
