Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an OSFP connector. Background Art

[0002] Octal Small Form-factor Pluggable (OSFP) is a pluggable package developed by the OSFP MSA organization. The OSFP connector supports multiple high-speed electrical channels with a total transmission speed of up to 400Gb / s (8 50G or 4 100G). Each 1U front panel can accommodate up to 32 ports, and each 1U switch slot has a transmission rate of up to 14.4Tb / s, so it is often called a high-speed cable connector. The existing OSFP connector generally includes an upper cover, a lower shell, and internal PCB components. In order to ensure a stable connection, the upper cover is used to hold the lower shell from both sides, or the lower shell is used to hold the upper cover from both sides, and then crimped to achieve a fixed connection, but this method is more troublesome.
