Deliver stable Gigabit Ethernet over multimode fiber with this 1000BASE-SX SFP. Built for 850 nm operation and up to 550 m reach, it is well suited to short- and medium-distance optical links inside buildings, across equipment rooms, and between network closets. The SFP form factor keeps deployment simple and preserves port density in compatible switches and routers. With an LC connector interface and 1 GbE signaling, this module aligns with common enterprise fiber plant designs and supports straightforward integration into existing multimode infrastructure. Choose this module when you need a practical optical option for shorter runs that still demand better distance and isolation than copper. It is a strong fit for access-layer uplinks, rack-to-rack interconnects, and other production links where predictable performance and compact hardware matter.
