The IBM 2498-2821 is a Brocade Small Form-Factor Pluggable (SFP) transceiver module designed for high-speed data transmission over long distances. It offers a maximum data rate of 8 Gigabits per second and is capable of transmitting data up to 10 kilometers over single-mode fiber, making it an ideal solution for extended network connections. This transceiver utilizes a long wave (LW) laser, operating at a wavelength of 1310nm, to achieve its long-distance reach with minimal signal loss. The LC duplex connector ensures compatibility with a wide variety of networking equipment. Its capability to operate over vast distances without significant degradation of the signal makes the IBM 2498-2821 a valuable component for connecting distributed IT environments, such as data centers or corporate campuses. It integrates smoothly into existing Brocade-enabled network infrastructures, offering a reliable, high-performance solution for expanding network reach.
