Product Description
The 3Com 3CSFP81FRU is a Small Form-factor Pluggable (SFP) transceiver, also commonly referred to as a mini-GBIC (Gigabit Interface Converter). This particular module is designed for lower speed Ethernet connections, operating at 100 Megabits per second (Mb/s). It is intended for use with multi-mode fiber (MMF) optic cables, which are typically used for shorter distances compared to single-mode fiber. The 3CSFP81FRU supports transmission up to 2 kilometers, making it suitable for connecting devices within a building, across a campus, or between adjacent facilities. The module utilizes a duplex LC connector, which is the standard for MMF connections, ensuring a secure and reliable physical link. The 3CSFP81FRU is a component used in network switches, routers, or other networking equipment to provide flexible and modular fiber optic connectivity for legacy or specific 100Mbps network segments.
