Robust SFP/MSA Connectors in Single and Quad Versions

Press release date: November 16, 2009

Robust SFP/MSA Connectors Pfarrkirchen, Germany, November 16, 2009 - For high-speed data transmission in the Gbps range, pluggable transceivers have, due to their flexibility, almost completely replaced hardwired copper or fiber-glass interfaces in most networking applications. For mounting of these miniaturized Small Form Factor Pluggable (SFP) modules with reliable contacts, SUYIN now offers extremely robust, simple and fast-mounting SFP connectors in single and quad versions. The SUYIN plug-in positions fully comply with the Multi-Source Agreement (MSA). In keeping with the MSA, all transceiver manufacturers have obligated themselves to observe binding, detailed agreements for physical, electrical and optical specifications, thus ensuring interoperability and universal compatibility. These specifications are defined in different standards: SFF-8432 (cage), SFF-8083 (mating interface and performance) and SFF-8431 (electrical interface).

SUYIN's right-angle SMT SFP/SMA connector consists of a bottom plate with the 20-pin, surface-mount contact unit as well as a high-temperature-resistant plastic insulation cover in accordance with UL94 V-0, and a robust cage. The bottom plate and cage are fastened together with high-strength positive latching using a patented "crocodile-style" snap-in mechanical connection. The cage itself is mounted sturdily on the printed circuit board using eight partially reinforced (and patented) press-fit connections. Due to the patented cage design, no shape distortion takes place, even after one thousand mating cycles. For LED signal indication on the front panel, both the single and quad versions can be fitted with "light pipes" in just three easy steps. The electrical contacts are made of a copper alloy and are specified for 250 mating cycles. Maximum insertion and maximum extraction forces are specified at 40 N and 11.5 N respectively, the maximum contact resistance at 20 mW, and the minimum insulator resistance at 500 MW. The SFP/MSA-compliant connector design makes it possible to hot-swap all kinds of transmission media. For the single version, the mechanical dimensions are 48.73 mm x 14.5 mm x 9.45 mm (L x W x H). SFP/SMA single and quad connectors are available immediately in sample quantities.
