Side-by-Side Comparison Fiber Connectors

MPO / MTP vs. SC

Comparing 2 standards across 12 specifications. 12 key differences identified.

Comparing:
MPO / MTP
SC

The MPO connector (Multi-fiber Push On, TIA-604-5 / FOCIS-5; US Conec MTP) is a high-density parallel optical connector utilizing a precision molded rectangular MT ferrule that houses 8, 12, 16, 24, 32, or 72 optical fibers in a single push-pull housing, standard for 40G, 100G, 400G, and 800G multi-lane transceivers.

The SC connector (Subscriber Connector / Standard Connector, TIA-604-3 / FOCIS-3) is a push-pull optical fiber connector developed by NTT. Utilizing a 2.5 mm ceramic ferrule and a square molded plastic body, it is a primary standard in telecommunications and FTTH GPON/EPON installations.
