Both adapter ends are SC receptacles, so it acts as a straight-through inline splice point — no hybrid conversion. The zirconia ferrule provides the precise alignment required for single-mode and multimode links, with a typical insertion loss well under 0.5 dB (manufacturer spec). The housing is synthetic resin with a snap-in flange mount, so it locks into a rectangular panel cutout without extra hardware. A dust cap is included to protect the ferrule end-face when the port is unmated. ## Mounting and Environmental Range Mounts via panel mount with flange and snap-in retention — push it into the cutout until the latches engage. No screws or nuts needed, which speeds field installation. Not rated for outdoor or washdown environments without additional enclosure protection.","metaTitle":"Hirose HSC-A3-D1(21) SC Simplex Coupler, Zirconia Ferrule","metaDescription":"Hirose HSC-A3-D1(21) SC simplex coupler with zirconia ferrule, panel mount snap-in, -25°C to 70°C.

The coupler itself is passive — it aligns the ferrules of two SC connectors; the fiber type (single-mode or multimode) depends on the patch cables plugged in. For single-mode, use UPC or APC polish SC connectors as appropriate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/HSC-A3-D1~121~2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/hirose-electric-co-ltd/HSC-A3-D1~121~2 when reusing this data.
