| 摘要 |
A coaxial opto-electronic device used for SFF (Small Form Factor) and SFP (Small Form-Factor pluggable) opto-electronic transceiver module comprises an opto-electronic TO CAN (201) having a cap border (106) at one end, a metal tube (203) disposed around the opto-electronic TO CAN (201), and an isolation ring (202) interposed between the end face of the metal tube (203) and the cap border (106). The coaxial opto-electronic device allows the device's metal case ground to be insulated from the inner data ground, and at the same time, the device outer form is small enough and the size of inner part thereof is enlarged.
