The SFPSXMM is 850nm gigabit multi-mode SFP fiber optical transceiver - LC 550m is built to comply with MSA (multi-sourcing agreement) standards to offer a cost-effective way to increase performance and connectivity of your fiber-connected network devices. Using a short wavelength (850nm) VCSEL laser diode, enabling a maximum cable distance of 550m (0.3 miles) over multi mode fiber, this small form factor pluggable (SFP) gigabit multi mode module can be installed into any fiber networking devices with an MSA compliant SFP port, providing a simple solution to upgrade existing network devices to connect to remote locations using LC terminated multimode fiber.
