Detailed Specifications
HPE 1990-4635 10GBASE-SR SFP+ MMF Transceiver
Overview
The HPE 1990-4635 is a hot-pluggable SFP+ optical transceiver module designed for 10 Gigabit Ethernet links over multimode fibre. It operates with an 850 nm VCSEL laser and duplex LC connectors, making it suitable for server-to-switch and switch-to-switch uplinks in data-centre and campus networks. Rated for distances up to ~300 m over OM3 fibre, the module supports full line-rate 10 Gb/s with low latency and integrates seamlessly into HPE/Aruba networking platforms. It is ideal for high-density fibre deployments where rack-to-rack or row-to-row connectivity is required and where optical upgrades are preferred over copper cabling. With its standard SFP+ form-factor and optical compatibility, the module allows engineers to maintain full-bandwidth links while avoiding the complicating factors of active optics.
