Shenzhen Kezhonglong Optoelectronic Technology Co., Ltd. — 2 prefixes (MA-L)

Shenzhen Kezhonglong Optoelectronic Technology Co., Ltd. holds two IEEE MA-L OUI assignments, 88:E6:28 and 5C:FF:FF, both registered from addresses in the Xinfu Industrial Park area of Baoan District, Shenzhen, Guangdong — one of the two raw registry rows lists the country field as "US" despite the Shenzhen street address, which reads as an IEEE registry data-entry artifact rather than an actual relocation, and is reported here as registered rather than silently corrected. The company is more than a bare single-OUI registry line: it appears as an active supplier storefront on made-in-china.com and in HKTDC's sourcing directory, and a Chinese business registry (cnverify.com) lists it as an active limited company with a named legal representative. FCC equipment-authorization records under grantee code 2AF2K show two WiFi Module filings — 2AF2K-WM415 (November 2015) and 2AF2K-WM524 (September 2017) — corroborating that the OUI blocks were used in actual networking hardware (WiFi modules for routers and IoT devices), a distinct product line from the optoelectronic/3D-eyewear business implied by the company name. No CVEs or security advisories were found for the company or its named modules in a targeted search, though that reflects an absence of findings rather than a confirmed absence of issues.

IEEE assignments

88:E6:28 and 5C:FF:FF → Shenzhen Kezhonglong Optoelectronic Technology Co.,Ltd, both MA-L [Confirmed] — the IEEE MA-L registry lines 2383, 35245 (cached IEEE MA-L registry)

Registered addresses

88:E6:28 → Floor 3, Bldg. 5, Area B, Xinfu Industrial Park, Chongqing Rd., Baoan Dist, Shenzhen, Guangdong, CN; 5C:FF:FF → 3/F, B5 Building, Xinfu Industrial Park, Heping Village, Shenzhen, Guangdong 518101 (raw CSV country field reads "US" despite the Shenzhen street address) [Confirmed, address text; the "US" country code is a registry data artifact, not a relocation] — the IEEE MA-L registry lines 2383, 35245

MA-M / MA-S assignments

none found for this org in the cached the IEEE MA-M registry / the IEEE MA-S registry registries [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry (no matching rows)

Assignment dates

IEEE's public OUI/MA-L data publishes no registration or assignment date for either block; none fabricated here [Confirmed] — the IEEE MA-L registry (Registry/Assignment/Organization Name/Organization Address columns only, no date column)

Third-party date artifacts (not IEEE facts)

maclookup.app lists "Registration Date" 2013-09-12 for 5C:FF:FF and 2016-11-17 for 88:E6:28 — these are third-party database artifacts and must not be attributed to IEEE [Likely — single web source] — https://maclookup.app/vendors/shenzhen-kezhonglong-optoelectronic-technology-co-ltd

Company substance

active supplier storefront and sourcing-directory listing, plus a Chinese business registry record showing active LLC status with a named legal representative [Confirmed — corroborated across independent sources] — https://kezhonglong.en.made-in-china.com/, https://sourcing.hktdc.com/en/Supplier-Store/Home/Shenzhen-Kezhonglong-Optoelectronic-Technology-Co-Ltd/1X090U99, https://www.cnverify.com/company/Shenzhen-Kezhonglong-Optoelectronic-Technology-Co-Ltd

Device / product context

FCC grantee code 2AF2K carries two "WiFi Module" equipment-authorization filings — 2AF2K-WM415 (Nov 2015) and 2AF2K-WM524 (Sep 2017) — consistent with the OUIs being used in router/IoT WiFi modules; the company name also implies an optoelectronics/3D-eyewear product line, treated as a separate line of business [Confirmed for the FCC filings; Likely that the OUIs map specifically to these modules] — https://fccid.io/2AF2K, https://usermanual.wiki/KeZhongLong-Optoelectronic-Technology/WM415
