Frequently Asked Questions (FAQ)
Q1: What is the main difference between this QSFP28 connector and an SFP+ cage?
A1: The primary difference is the form factor and supported data rate. This product is a QSFP28 connector designed for larger, four-channel modules supporting 100G speeds, while SFP+ cages are for smaller, single-channel modules typically used for 10G applications.
Q2: Does this connector come with a heatsink or light pipe options?
A2: According to the product database, the S5C21H0A00BA4 model does not include a heatsink or light pipe. These are listed as separate options available for other models in the QSFP+ & QSFP28 cage series.
Q3: What are the available plating options for the contacts?
A3: The contacts are available with either 15 or 30 micro-inch gold plating to ensure optimal conductivity and corrosion resistance.
