Fiber Optical Transceiver 25G SFP28 LR stands as a cornerstone in contemporary optical networking solutions. Operating at the 1310nm wavelength via single-mode fiber, it provides a robust 10km reach. The duplex LC/UPC connectors exhibit a high level of engineering precision. Their UPC finish serves to suppress signal irregularities, safeguarding the clarity and accuracy of transmitted data. With the SFP28 form factor, network engineers can easily retrofit this transceiver into pre-existing network infrastructures. This allows for the establishment of a continuous 25G data pathway across the 10km expanse, thereby enhancing overall network performance and adaptability to meet the dynamic demands of modern applications.
