Overview
Aeluros Inc was a semiconductor company focused on integrated circuits for wireline communications. Founded in 2001, it operated in a specialized segment of the networking-equipment supply chain, developing physical-layer, or PHY, devices used to transmit and receive high-speed data over electrical and optical interfaces. Its principal area was 10 Gigabit Ethernet, a networking standard used in enterprise, carrier, storage, and data-center infrastructure. The company’s products were intended for use by equipment manufacturers rather than ordinary consumers. Its PHY devices could be incorporated into 10 Gigabit Ethernet line cards and optical modules, including industry-standard form factors such as XENPAK, SFP, and XFP. This positioned Aeluros as a component supplier whose value depended on electrical performance, interoperability, power consumption, signal integrity, and compatibility with evolving networking architectures. Aeluros was associated with several technical achievements in 10 Gigabit Ethernet transceiver design. It was reported to have produced the first XAUI transceiver consuming less than one watt, an important characteristic for dense networking hardware where thermal limits and power budgets affect system design. The company also developed a transceiver capable of directly driving a 10 Gbit/s vertical-cavity surface-emitting laser, or VCSEL, reducing the need for additional interface components in certain optical implementations. Another area of development was integrated electronic dispersion compensation for 10 Gigabit Ethernet over multimode optical fiber. Dispersion compensation helps address signal degradation over fiber links and can improve usable reach and reliability. Aeluros remained an independent specialist for several years before merging with NetLogic Microsystems in October 2007. The transaction was valued at more than $70 million according to the cited reference material. The combination placed Aeluros’s high-speed Ethernet PHY expertise within a larger semiconductor portfolio. NetLogic Microsystems was later acquired by Broadcom in February 2012 in a transaction valued at approximately $3.7 billion. Following the 2007 merger and the subsequent integration of NetLogic into Broadcom, Aeluros no longer operated as an independent company or standalone brand in the form described by its original corporate history. The company’s historical significance rests primarily on its contribution to the development of lower-power and higher-performance 10 Gigabit Ethernet interface technology. Available reference material does not establish a separate consumer-facing product range, broad retail presence, independent public listing, current operations, or a continuing standalone management team.

Recent events
- 2012Broadcom acquires NetLogic Microsystems
Broadcom acquired NetLogic Microsystems in February 2012 for approximately $3.7 billion. Because Aeluros had previously merged into NetLogic, the transaction represented a later ownership change affecting the business that had absorbed Aeluros.
M&A - 2007Aeluros merges with NetLogic Microsystems
Aeluros merged with NetLogic Microsystems in October 2007 in a transaction reported as exceeding $70 million. The combination brought Aeluros's 10 Gigabit Ethernet physical-layer technology into NetLogic's broader semiconductor business.
