Source Photonics, Inc. — 2 prefixes (MA-L)

A MAC address beginning with 00:06:B5 or 00:1F:22 belongs to Source Photonics, Inc., typically seen on fiber-optic networking hardware such as pluggable optical transceivers (SFP, SFP+, SFP-DD, CFP, OSFP) and PON ONU/OLT modules for FTTx access networks.

Source Photonics holds two separate IEEE MA-L (24-bit OUI) assignments, both registered to the same Chatsworth, California address. Two independent blocks plus an active, product-bearing corporate presence separate this entry from a bare single-OUI shell registration.

The company markets a current product catalog spanning pluggable transceivers and a PON portfolio, including a publicly listed "XGS-PON MAC ONU" module — a subscriber-side device that embeds an Ethernet MAC, consistent with these OUIs addressing the MAC-facing side of ONU/OLT hardware rather than a MAC-less optical part. No source maps either prefix to one specific product model.

Third-party aggregator snippets mention a 1988 founding date and conflicting acquisition claims (one naming Francisco Partners, another an April 2026 date, another a "Dsbj, June 2025" deal); none were cross-verified against a primary filing or the company's own site, so those specifics are left Unknown rather than asserted. No CVE or malware/trojan association was found for the company or either prefix as of an August 2026 search.
