Micro and nano connectors are low profile, lighter weight and offer good connections for most routing signals in small electronics and modules. Micro and nano cabling to the connectors can be specifically designed to protect both cable and circuits and be more flexible to assist in routing.

that take advantage of our knowledge of wire and cable.” Southwire’s VDV tools include cable cutters, strippers, crimpers and punchdown tools, as well as cable tracers and testers.

Now even more express…

Seaborn Networks’ Seabras-1 submarine fiber optic cable, the first express submarine cable system between the USA and Brazil, has been increasedby 50percent toa6-fiber pair system with a maximum upgradeable capacity of 60Tbps. “We increased the system size in response to the significant pent-up demand on the route for lit capacity, spectrum and fiber pairs,” said Larry Schwartz, Seaborn’s CEO.

The system will connect New York and São Paulo, with a branch landing in Fortaleza, Brazil, and will come into service in 2016.

The new slim-lined 0.025" pitch connectors from Omnetics have integrated back-shells to save weight and space while achieving up to 85db of EMI isolation in noisy, high-speed environments. Systems can evolve with one part of the circuit being larger, and using micro-D size connectors at 0.05" pitch. The other end of the cable has little space available and may have multiple breakout modules that need nano-sized connections. Custom micro to nano-cables are readily configured, including metal mesh for noise shielding that is terminated on each connector using a 360º seal for noise protection. Polymer jackets canbeadded to theexterior of the shielded cable to provide softer and smoother feel, and protection of the cable.

Miniature cables and connectors

Condensing more electronics into smaller areas presents the designer with additional challenges. Micro and nano-connectors use smaller diameter cables, and allow signal routing adjacent to potentially noisy electronic processing equipment, but the cables themselves can create and carry inductively coupled noise that could interfere with other circuitry. In addition to cable design, nano-miniature and micro-miniature connectors are used to help squeeze into tightly designed spaces.
