book Page 1 Friday, April 19, 1996 9:53 AM CHAPTER 2 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.
book Page 2 Friday, April 19, 1996 9:53 AM 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.

The FE-100FX meets IEEE 802.3u standards. When connecting a fiber optic segment to the BRIM-E100 with the FE-100FX module installed, the network must meet the following requirements: Cable Loss Test the fiber optic cable with a fiber optic attenuation test set adjusted for an 850 nanometer (nm) wavelength.
book Page 4 Friday, April 19, 1996 9:53 AM Chapter 2: Cabling Requirements If you are installing this BRIM into a 100BASE-TX/FX environment with repeaters, use the repeater instruction manual to determine maximum cable lengths when laying out your network. UTP Maximum Cable Lengths An unshielded twisted pair copper segment in a 100BASE-TX environment may be no more than 100 meters in length.
