What This Guide Module Does
The TE Connectivity 787663-4 is a guide module — a mechanical alignment accessory designed for use with GBIC (Gigabit Interface Converter) connectors. It is not a connector itself; it fits into the GBIC cage or housing to guide the transceiver module into the correct position during insertion, preventing misalignment that can damage the delicate optical or electrical interface pins. This part ships in a Box package.
