Designed for harsh environments and extreme temperature ranges, the CISCO SFP-10G-SR-X module extends the family of 10 Gbps SFP+ modules by offering robust performance over multimode fiber in conditions where normal modules would fail. Suited for industrial settings, outdoor installations, or heated data centers, this module transmits data over distances up to 300 meters at an 850 nm wavelength on OM3 multimode fiber. Its extended temperature range capability ensures reliable data communications in environments subjected to temperature variances outside the norm for a typical data center. This adaptability without compromising on speed or reliability underpins its suitability for demanding applications across various sectors.
