What does Bundled Cable mean?
Bundled Cable essentially is an assembly of two or more cables continuously bound together to form a single unit prior to installation (sometimes referred to as loomed, speed-wrap or whip cable constructions).
What is the difference between RJ11 and RJ45 connectors
An RJ-11 is a 6-position 6-contact connector primarily used for telephone and modem line cords. An RJ-45 is a 8-position 8-contact connector modular plug or jack used with unshielded twisted pair cable, primarily used for telecommunications and patch cords.
What are the classification applications for cabling?
Application classes for cabling have been identified for the purpose of the ISO/IEC 11801 standard:
- Class A, ISO/IEC 11801 designation for twisted pair cabling rated to 100 KHz. Used in voice and low frequency applications. Comparable to Category 1 cabling. Not suitable for networking applications.
- Class B, ISO/IEC 11801 designation for twisted pair cabling rated to 1 MHz. Used in medium bit rate applications. Comparable to Category 2 cabling. Not suitable for networking applications.
- Class C, ISO/IEC 11801 designation for twisted pair cabling rated to 16 MHz. Used in high bit rate applications. Corresponds to TIA/EIA Category 3 cabling.
- Class D, ISO/IEC 11801 designation for twisted pair cabling rated to 100 MHz. Used in very high bit rate applications. Corresponds to TIA/EIA Category 5 cabling.
- Class E, ISO/IEC proposal for twisted pair cabling rated to 250 MHz. Corresponds to the proposed TIA/EIA Category 6 cabling standard.
- Class F : cabling is characterized up to 600 MHz
- Optical Class : optical fiber links are characterized up to 10 MHz and above.
What is a Patch Panel?
Patch panels are convenient groupings of RJ-45 jacks. They come in 12, 24, and 48 ports, and typically are rack mounted. The front sides are RJ-45 jacks; the back sides are punch-down blocks that provide connectivity or conducting paths. They are classified as Layer 1 components.
