  • Page 14: Chapter 2 Cabling Requirements

    CABLING REQUIREMENTS This chapter describes the cabling requirements for the BRIM-E100. The network must meet the requirements and conditions specified in this chapter to obtain satisfactory performance from this equipment. Failure to follow these guidelines could result in poor network performance. 2.1 UTP CABLE SPECIFICATIONS The BRIM-E100 with an FE-100TX Fast Ethernet Interface Module installed provides an RJ45 connection that supports Unshielded Twisted...
  • Page 15 Chapter 2: Cabling Requirements Jitter Intersymbol interference and reflections cause jitter in the bit cell timing, resulting in data errors. A 100BASE-TX link must not generate more than 1.4 nanoseconds (ns) of jitter. If the cable meets the impedance requirements for a 100BASE-TX link, jitter should not be a concern. Crosstalk Crosstalk is caused by signal coupling between the different cable pairs contained within a multi-pair cable bundle.
