Chengdu KT Electronic Hi-Tech Co., Ltd. — 3 prefixes (MA-L)

A MAC address beginning 48:F8:FF, DC:A7:06, or E8:9F:EC belongs to CHENGDU KT ELECTRONIC HI-TECH CO.,LTD, a Chengdu-based manufacturer of CATV and broadband access-network equipment — EOC headends, GEPON/xPON OLT and ONU units, optical nodes/transceivers, and IPTV encoders.

The IEEE MA-L registry lists three separate 24-bit OUI blocks under the identical organization name and address (No.9, 3rd Wuke Road, Wuhou District, Chengdu, Sichuan Province, CN 610045). Holding three independently-assigned blocks under one registrant is a stronger substance signal than a single bare registration — it typically reflects real production volume exhausting prior allocations rather than a shell filing.

Independent B2B directory listings (Alibaba, Made-in-China, Global Sources) consistently describe the same operation: a company founded in 1992 running a roughly 50,000 sqm manufacturing/R&D facility with SMT and wave-soldering lines, reporting annual output above 800,000 units and revenue above $50M USD, ISO 9001:2000 certified and 3C certified since 2004. These are directory claims, not primary-source-confirmed, so they are tagged Likely rather than Confirmed.

A separately-named registrant, "Chengdu KT Electric Co. of High & New Technology," holds a fourth OUI (00:0F:1E) at a different Chengdu address. The near-identical name suggests a possible earlier company name or affiliate, but nothing corroborates it as the same legal entity, so it is noted as related rather than merged into this vendor's prefix set.

No registration date is recorded for any of the three prefixes. IEEE's public MA-L data has no date field; third-party MAC-lookup aggregators display per-prefix dates that are database-scrape artifacts, not IEEE-published facts, and are excluded here on that basis.

IEEE assignment

3 prefixes (48:F8:FF, DC:A7:06, E8:9F:EC) → CHENGDU KT ELECTRONIC HI-TECH CO.,LTD, registered Chengdu, Sichuan, CN [Confirmed] — IEEE MA-L (standards-oui.ieee.org/oui/oui.csv)

Related / possible predecessor entity

"Chengdu KT Electric Co. of High & New Technology" holds separate OUI 00:0F:1E at a different address (No.2 Gaopeng Dong Road); plausible earlier name given the near-identical name and Chengdu location, but not confirmed as the same legal entity — do not merge [Likely] — IEEE MA-L

Registration dates

Unknown — IEEE's public OUI/MA-L registry has no date field; third-party MAC-lookup sites (maclookup.app, mac.lc, cleancss.com) show per-prefix dates that are database-scrape artifacts, not IEEE facts [Confirmed] — IEEE MA-L

Security context

no CVEs, security advisories, or documented vulnerabilities found for this vendor or its product lines; absence of findings, not a confirmed clean record [Likely] — general CVE/CISA search

Website

no confirmed official corporate domain found; only third-party B2B directory listings identified [Unknown] — n/a

Analyst note

three independently-registered MA-L blocks plus a corroborated multi-decade CATV/broadband-equipment manufacturing operation place this vendor above the bare-shell abstention threshold; treat these prefixes as telecom/ISP-side network infrastructure rather than end-user client devices
