1888617-1 QSFP+ Cage Notes
For layout planning, TE specifies a through-hole press-fit mounting approach and provides PCB-related guidance in the customer drawing. The drawing also identifies datum A as the top surface of the host board and notes that the product is intended for specific host-board mechanical constraints, including the minimum board thickness requirements mentioned above.
To ensure optimal performance and assembly, please adhere to the following technical guidelines:
- PCB Requirements: The recommended minimum board thickness is 1.45 mm for single-sided applications and 2.2 mm for double-sided (belly-to-belly) applications.
- Compatibility: This cage is designed to mate with all QSFP MSA compatible transceivers.
- Spring Finishing: The EMI springs feature a finish of 0.8 µm minimum Tin over 0.8 µm minimum Nickel.
- Trace Clearance: Surface traces are permitted within the specified area, provided they do not contact the cage standoffs.
- Identification: Each unit includes a 2D barcode and date code (YYWWD) for streamlined inventory tracking and quality control.
