Hisense Broadband Multimedia Technology Co., Ltd. (HBMT) — 7 prefixes (MA-L)

Hisense Broadband Multimedia Technology Co., Ltd. (HBMT) holds seven MA-L prefixes and is a distinct legal entity from the far better-known Hisense Visual Technology Co., Ltd. — the TV/VIDAA maker already covered under a separate vendor entry in this repo — despite sharing the "Hisense" brand name. HBMT is a Qingdao-based telecom-hardware manufacturer founded in 2003 with 4,000+ employees, building optical transceivers (GPON/XGPON/50GPON and 10G–800G data-center/telecom modules), active optical cables, ONU/ONT boxes, CATV/SATV/IPTV set-top boxes and gateways, and some WiFi 6 routers. Six of the seven registered prefixes carry an identical organization-name string and address (Song ling Road 399, Qingdao, CN 266000); the seventh, AC:4A:FE, is registered under a differently capitalized and punctuated organization string at a separate Qingdao address, so it is reported here rather than silently merged into the same group. In March 2025 HBMT consolidated its North American and Thailand operations into a new Delaware entity, Ligent Inc., and its official site now presents primarily as the Ligent brand. No CVEs were found specifically attributable to HBMT's own product line, and none of the Hisense Visual Technology / VIDAA security history applies to this separate company.

Related-but-distinct entity

Security context

no CVEs found specifically attributable to HBMT's own product line (ONTs/STBs/transceivers); a general "Hisense" vendor CVE search could not be confirmed as HBMT-specific rather than belonging to Hisense Visual Technology [Likely — absence of evidence is not confirmed absence] — https://www.cvedetails.com/vendor/17128/Hisense.html
