The characteristics, classification and utilities of Fiber Optic Patch Cord

The fiber optic patch cord is connected on at either end of the cable with various types of (mainly RJ45) connectors.  The matter of fact it allows the cable quickly and suitably connected to the CATV, an optical switch or other telecommunication equipment. The wide layer of protection is used to connect the optical transmitter, receiver, and the terminal box. This is well known as "interconnect-style cabling.

The fiber patch cable is seeing broad adoption in applications that comprise telecommunication and data communication. With numerous business and enterprise gathering great benefits from it, fiber patch cable represents by far the most sufficient and common bandwidth feeder. As those gigabit-capable networks growth, the fueling capacity and speed search further drive fiber patch cord deployment.

General characteristics of Patch cords and other optical fiber Cables:

1. Good interchange
2. High return loss
3. Excellent environmental adaptability.
4. Good repeatability
5. Low insertion loss

General length of Patch Cords:

Ordinary cables measure 125 µm in diameter. The 50 / 62.5 µm for multi-mode cables and inner diameter measures 9 µm for single-mode cables.

The progress of "reduced bend radius" fiber in the mid- the 2000s, enabled a trend towards smaller cables. Each unit of diameter trimming in a round cable, build a disproportionate corresponding reduction in the space the cable occupies.

Types of fiber optic Patch Cords:

• Single mode fiber patch Cord: Single-mode fiber optic patch cords use 9/125 micron bulk single-mode fiber optic connectors and single-mode fiber cable at both ends. The single-mode fiber optic cord jacket color is usually yellow.

• Multimode fiber patch cord: Multimode fiber optic patch cords use 50/125 micron or 62.5/125 micron bulk multimode fiber cable and terminated with multimode fiber optic connectors at both ends.  The multimode fiber optic cord jacket color is usually orange.

• 10gig multimode fiber optic patch cord: 10Gig multimode fiber patch cables are specially designed 50/125 micron fiber optimized for 850nm VCSEL laser-based 10Gig Ethernet. They are backward compatible with providing close to three times the bandwidth of traditional 62.5/125 multimode fibers and existing network equipment . 10 Gigabit is rated for distances up to 300 meters using 850nm Vertical Cavity Surface discharge Lasers. 10Gig fiber optic cord jacket is usually aqua.

Advantages and disadvantages of patch cord:

Advantages:

1. Patch cord is an electrical or optical cable, which is used to connect one electronic or optical device to another for signal routing.
2.  They are used to connect patch panels to network devices.
3.  Fiber patch cord supplies you a low attenuation connection between the fiber network cables or from the cable to the device.
4.  With a multi-mode fiber patch in deployment, one need not worry about the speed, bandwidth and transfer direction of data.

Disadvantages:

1. More expensive than other short reach direct-attached options.
2. Limited to 5 m to 10 m and coaxial cable can be stiff and bulky in high-density deployments.
3. Limited to less than 10 m reconfigurations of length or failed transceiver requires replacement of the entire assembly.
