摘要：

A 5-Gb/s data modulation and transmission is investigated using Fabry-Perot InGaAs quantum-dot lasers emitting at approximately 1.3 pm. Error-free transmission of 5-Gb/s data at room temperature over 4 km of single-mode fiber (SMF) and over 500 In of installed grade multimode fiber are demonstrated for the first time. The temperature dependence of the data modulation performance is also studied. We report error-free 2.5-Gb/s data modulation up to 50 degreesC and transmission over 4 km of SMF with a Q factor penalty of 0.5 dB. Error-free 5-Gb/s data modulation erved up to 30 degreesC and 5-Gb/s data transmission over 4 km of SMF with a Q-factor penalty of 0.8 dB is obtained at 40 degreesC. The lack of overshoot and ringing in the eye diagrams is attributed to the large damping factor observed under small-signal modulation.
