Accelink Technologies Co., Ltd. — 6C:2E:33 (MA-L)

Accelink Technologies Co., Ltd. is a Wuhan-headquartered optical-communications company that holds the IEEE MA-L block 6C:2E:33, registered to the exact organization name "Accelink Technologies Co.,Ltd." at 88 Youkeyuan Road, Wuhan, Hubei, CN 430074. This is not a bare single-OUI shell: Accelink is a publicly-traded firm (Shenzhen Stock Exchange, 002281.SZ) that traces its roots to 1976 and is widely described as a top-ten global optical-device supplier. Its documented product line spans optical transceivers (SFP/SFP+/QSFP), DWDM/CWDM and OADM/ROADM systems, EDFA/RFA optical amplifiers, and OTN transport subsystems for backbone, metro, access, 5G, and data-center networks — hardware whose management interfaces plausibly carry Ethernet MACs drawn from this allocation. The registry snapshot shows only this single MA-L /24 block; no matching MA-M or MA-S sub-blocks appear in the cached registries, and whether Accelink holds additional OUIs elsewhere was not independently confirmed this session. IEEE publishes no assignment date for OUIs, so no registration date is recorded here; third-party lookup tools that show a "registration date" for this prefix are surfacing a database artifact, not an IEEE fact.

IEEE assignment

6C:2E:33 → "Accelink Technologies Co.,Ltd.", 88 Youkeyuan Road, Wuhan Hubei CN 430074 [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI, ~16.7M addresses) [Confirmed] — the IEEE MA-L registry. Single exact match; the aggregator maclookup.app also lists 6C:2E:33 as MA-L [corroborating] — https://maclookup.app/vendors/accelink-technologies-co-ltd

Registered address / country

88 Youkeyuan Road, Wuhan, Hubei, CN 430074 (registry address) [Confirmed] — the IEEE MA-L registry

Company status

active, publicly traded on the Shenzhen Stock Exchange (002281.SZ) [Likely] — https://en.wikipedia.org/wiki/Accelink_Technologies, https://www.accelink.com/

Company substance

identifiable operating company, founded 1976 (roots), described as a top-ten global optical-device supplier; NOT a single-OUI shell [Likely] — https://en.wikipedia.org/wiki/Accelink_Technologies, https://www.accelink.com/

Device types

optical transceivers (SFP/SFP+/QSFP), DWDM/CWDM/OADM/ROADM systems, EDFA/RFA optical amplifiers, OTN transport subsystems [Likely] — https://www.accelink.com/en/lighting_your_dreams/OpticalTransportNetworks.html

Prefix-to-product link

no vendor document was found tying 6C:2E:33 to a named product line; the device-class association is inferential (management ports on optical/transport gear carry Ethernet MACs), not vendor-confirmed at the prefix level

[Likely] — https://www.accelink.com/en/lighting_your_dreams/1747185910983753730.html

Multiple OUI assignments

Unknown — no second block found in the IEEE MA-M registry or the IEEE MA-S registry (no Accelink row in either) and none surfaced in web sources, but the authoritative IEEE bulk registry was not queried directly this session; do not record as a confirmed single-OUI vendor

[Unknown] — the IEEE MA-M registry, the IEEE MA-S registry

Registration date

Unknown — IEEE publishes no OUI assignment/registration date; the cached registry CSVs carry no date column. maclookup.app displays "Registration Date: November 24, 2010" but that is an explicit third-party database artifact, NOT an IEEE fact — do not attribute it to IEEE.

[Unknown] — the IEEE MA-L registry, https://maclookup.app/vendors/accelink-technologies-co-ltd

Security / abuse context

none found — no CVEs, advisories, botnet reports, or abuse associations were located for Accelink or the 6C:2E:33 prefix (absence of evidence, not a clean bill of health) [Unknown]
