Product Description
The 3Com 3C168915 is a high-density expansion module specifically designed for the 3Com 7700 series of modular network switches. This module provides 48 individual ports that operate at Fast Ethernet speeds (100 Mbps) and utilize the 100Base-FX standard, which is based on fiber optic transmission. The use of SFP (Small Form-Factor Pluggable) slots for each port means that the specific type of fiber optic transceiver (e.g., for short-reach, long-reach, or specific wavelengths) can be chosen and installed by the user, offering significant flexibility in network design. This module is ideal for environments that require a large number of fiber optic connections at Fast Ethernet speeds. It can be used to connect numerous end devices, extend network segments over longer distances than copper cabling allows, or to provide uplinks from access layer switches to distribution or core layers where fiber is preferred. The 48-port density helps in consolidating network infrastructure and simplifying cabling within racks or wiring closets. By equipping the 7700 series switches with the 3C168915 module, network administrators can significantly increase the number of available network ports while leveraging the benefits of fiber optic connectivity, such as immunity to electromagnetic interference and greater transmission distances. This makes it a valuable component for building robust and scalable network infrastructures in enterprise, campus, and service provider environments that rely on reliable Fast Ethernet connectivity over fiber.
