Multimode Speciﬁcations for the FE-100FX

2.2 MULTIMODE SPECIFICATIONS FOR THE FE-100FX

The BRIM-E100 supports the Cabletron Systems FE-100FX. 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. This test veriﬁes that the signal loss in a cable is within an acceptable level. The maximum loss for a multimode ﬁber optic cable is 11.0 decibels (dB).

Fiber Optic Budget and Propagation Delay

Determine the maximum ﬁber optic cable length by calculating the ﬁber optic budget delay and total network propagation before ﬁber optic cable runs are incorporated in any network design.

Fiber optic budget is the combination of the optical loss due to the ﬁber optic cable, in-line splices, and ﬁber optic connectors.

Propagation delay (collision delay) is the amount of time it takes data to travel from the sending device to the receiving device. Total propagation delay allowed for the entire network is 256 bit times (2.56 ∝s). If the total propagation delay between any two nodes on the network exceeds

2.56∝s, then further segmentation of the network through the use of bridges or other devices is required.

2.3 NETWORK CABLE LENGTHS

This section details the maximum network cable lengths speciﬁed by the IEEE 802.3u standard. As stated in the previous sections, the physical size of the network is limited primarily by propagation delay. The propagation delay cannot exceed 256 bit times.

A 100BASE-TX/FX network might use all copper (UTP) links, all ﬁber links or a combination of both. The maximum length of any segment is determined by the types and combination of links and by the type of repeater (if any) between segments. IEEE 802.3u standards specify two repeater classes (Class 1 and Class 2) and the maximum cable lengths for each media type.
