INTRODUCTION The original publication of ANSI/TIA/EIA-785 contained requirements for both receiver bandwidth and receiver stressed receive sensitivity. The inclusion of the receiver bandwidth specification was technically duplicative to the receiver stressed receive sensitivity and leads to unwarranted limitations in transceiver designs. This addendum removes the requirements for receiver bandwidth fi-om ANSI/TIA/EIA-785. Two errors related to the stressed receive sensitivity test specifications are also corrected. The BER specified in Table 4-2 Note 4 is aligned with the system BER, and a typo in the vertical eye closure penalty equation in Annex A is corrected. 2. PURPOSE AND SCOPE The purpose of this Addendum is to remove Section 4.3.2.8 “Receive electrical 3 dB upper cutoff frequency” and related references within ANSI/TIA/EIA-785-2001, and to correct two errors related to the stressed receive sensitivity test specifications. 3.

Average coupled optical output power, rise time, fall time, and jitter (DCD, DDJ, and RJ) shall be measured at the output end of the fiber optic cabling used in the channel (see FDDI PMD annex B). The output end is defined as the end that connects to the receiver. The data pattern for this measurement shall be a stream of Halt symbols. (Fast Ethernet /I/ code-groups) Refer to normative annex A for additional details and alternative test methods. Data-dependent jitter is specified for the test data pattern specified in FDDI PMD annex A. Annex A also provides possible test methods. Random jitter is s ecified as the peak-peak value where the probability of exceeding that value is equal to 2.5 x lo-. For a Gaussian probability distribution, the resulting peak-peak value is equal to 12.6 times the rms value. Stressed receive sensitivity is measured with a conformance test signal for BER= 2.5 x 10-l at the eye center, as specified &Annex A of this Standard. 3.3 In Annex A, delete: “Vertical eye-closure penalty = 10 log (AO / AI) dB” and substitute: “Vertical eye-closure penalty = 10 * log (Ao / AI) dB.” 2 Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/30/2007 20:04:11 MDTNo reproduction or networking permitted without license from IHS -,-,- Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/30/2007 20:04:11 MDTNo reproduction or networking permitted without license from IHS -,-,- Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/30/2007 20:04:11 MDTNo reproduction or networking permitted without license from IHS -,-,-
