Product Description
The IBM 26K7941-01-CT is a high-performance Small Form-Factor Pluggable (SFP) transceiver module specifically designed for Fibre Channel (FC) networks. Operating at a data rate of 4Gb/s, this module is suitable for demanding storage area network (SAN) environments where high throughput and low latency are critical. It adheres to the SFP Multi-Source Agreement (MSA), ensuring compatibility with a wide array of networking switches, host bus adapters (HBAs), and other SAN infrastructure components that support SFP transceivers. This particular SFP module utilizes an 850nm wavelength, which is characteristic of Shortwave (SW) transceivers used with multimode fiber (MMF). It is engineered to achieve reliable data transmission over distances of up to 150 meters. The use of multimode fiber makes it an economical choice for shorter links within data centers or between adjacent racks and buildings, where the cost of single-mode fiber might be prohibitive. The transceiver features a standard duplex LC connector, providing a robust and widely adopted physical interface for connecting the fiber optic patch cords. Its pluggable design allows for hot-swapping, enabling administrators to install or replace modules without disrupting network operations. The IBM 26K7941-01-CT is a key component for building efficient and scalable Fibre Channel SANs, offering a balance of performance, reach, and cost-effectiveness for short-distance connectivity.
