The TO-46 header has been commonly used for vertical cavity surface emitting laser (VCSEL) and photodetector package. The high-frequency characteristics of a TO-46 header were measured using our special K-type adaptors and simulated through a three-dimensional full wave electromagnetic simulator. The measurement and simulation results show the TO-46 header provides a resonance-free transmission bandwidth over 40-GHz and reflection loss below -10-dB within 31-GHz, with an ideal 50- terminal. The 25-Gb/s and 40-Gb/s eye diagrams through a TO-46 header were measured using our measurement setup, and the eye diagrams are clear enough. In addition, the single-end and differential-end equivalent circuit models of a TO-46 header were established and verified. The TO-46 header provides a low-cost and high-speed package solution and can be applied in 21-Gb/s fiber channel technology and 100-Gb/s (4x25-Gb/s) Ethernet (100GbE) network.
