Contents General Overview Testing Results Project Pending Eye Pattern Bit Error Rate Project Pending

Purpose To implement Gigabit Ethernet at an affordable price for the general consumer

General Overview The opto-electronic module from the Gigabit Ethernet card was isolated and mounted on an external evaluation board to test its performance in data transmission.

Test Setup for Gigabit Ethernet

Interpretation of the Eye Pattern

Experiment Result (PN-7 Encoding with 10ft. Cable)

Experiment Result (PN-7 Encoding with 100ft. Cable)

Bit Error Rate The bit error rate (BER) is the percentage of bits that have errors relative to the total number of bits received in a transmission

Inferences Eye Pattern Results BER Results It can be inferred that the evaluation board can perform data transfer at Gigabit Ethernet speed with acceptable performance.

Project Pending Interfacing the evaluation board to the Gigabit Ethernet card to verify transmission performance with actual real-time data

Circuit Setup

Possible Challenges Impedance Matching on Ethernet Board Soldering Concerns
