Abstract
SummaryThe 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‐Ω 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 (4 × 25‐Gb/s) Ethernet (100 GbE) network.
