SENKO SN® Standard Connector

The SENKO SN® Standard Connector is a Very Small Form Factor (VSFF) duplex optical connector engineered to meet the escalating demands of modern data centers. Utilizing proven LC ferrule technology, the SN® connector offers a threefold increase in fiber cabling density compared to traditional Duplex LC connectors — making it an ideal solution for high-density patching and advanced network architectures.

Designed for compatibility with QSFP-DD, OSFP, and SFP-DD transceivers, the SN® Standard Connector supports next-generation 400G data rates while the integrated push-pull boot ensures fast, tool-free installation even in the most densely packed panels.

SENKO SN® Standard Connector

Built on proven LC ferrule technology in a compact VSFF housing, the SN® Standard Connector delivers up to three times the port density of standard Duplex LC. The integrated push-pull boot enables easy insertion and extraction without tools — even in high-density panels where adjacent connectors leave minimal clearance. Compatible with 1.6 mm and 2.0 mm jacketed cables with internal strain relief for lasting mechanical durability.

Frequently Asked Questions

The SENKO SN® Standard Connector uses the same proven LC ferrule technology but in a Very Small Form Factor (VSFF) housing that is significantly more compact. This results in up to three times the fiber cabling density compared to traditional Duplex LC connectors, making the SN® ideal for high-density patching environments where maximizing port count per rack unit is critical.

The SN® Standard Connector is compatible with QSFP-DD, OSFP, and SFP-DD transceiver form factors. These are the primary transceiver formats used in 400G data center deployments, and the SN® supports up to four connectors per transceiver, maximizing the fiber density of each port.

The SN® Standard Connector is suitable for termination to both 1.6 mm and 2.0 mm round jacketed cables. It incorporates a ruggedized jacket and internal strain relief to ensure reliable mechanical performance across installation environments.

The integrated push-pull boot allows technicians to insert and remove the SN® connector using simple finger pressure — push to seat, pull to release — without requiring extraction tools or additional accessories. This is especially valuable in high-density panels where adjacent connectors leave minimal clearance for conventional latch-release mechanisms.

The SENKO SN® Standard Connector delivers the density, performance, and ease of use that next-generation data centers demand. Whether you're building out 400G infrastructure, maximizing patch panel density, or future-proofing your network fabric, the SN® is the connector engineered for what comes next. Request a Quote →
