Lenovo 81Y1622 SFP SX 1 Gbps 850 nm | Multimode, LC, Enterprise

Designed for short-reach fiber where density and consistency matter, this Lenovo SFP SX transceiver supports 1 Gbps Ethernet over multimode fiber at 850 nm. The LC connector keeps cabling familiar and easy to manage, while the SFP form factor preserves port density across switches, routers, and server-side uplinks. This is the right class of optic for intra-rack, inter-rack, and same-building links where long-haul optics would add cost without adding value. SX optics are widely used because they align with common multimode plant designs and keep deployment straightforward for infrastructure teams standardizing on 1 Gbps access and aggregation layers. For procurement teams, the appeal is clear: a focused transceiver for short-distance Ethernet transport, without the overhead of over-specifying reach. For operations teams, it means a familiar optical profile that fits established multimode environments and supports clean, repeatable rollouts.
