Panduit's small-form-factor (SFF) Opti-Jack is first to offer full duplex operation in an RJ interface and obtain FOCIS designation from TIA.

Panduit says that the Opti-Jack is half the size of duplex SC connectors. The previous adapter is now integrated, so fewer components are needed. Footprint is the same as copper connectors, so it can be integrated into existing panels.

Panduit has developed Opti-Jack for fibre to the desktop and backbone as well as campus-wide fibre installations. Performance exceeds the requirements of TIA/EIA 568.

Designed for simple, three-stage field installation, the Fujikura MT-RJ connector — suitable for SM10/125, G150/125 and G162.5/125 fibres — uses a new mechanical splice technology and pre-polished end-faces for the attachment of optical cables.

Each connector consists of a housing body, mini-MT ferrule, spring and spring push, and protective boot to prevent damage or ingress of contamination at the housing inlet.

Installers simply prepare the fibres and place the connector into its assembly tool, open the mechanical splice with a wedge and insert the fibre, then remove the wedge and connector from the assembly tool before fitting the rubber boot.

Average insertion loss is 0.6dB with SM10/125 fibres and 0.1dB with other types. Return loss is at least 40dB.

Options are available for use with either 0.75mm pitch, two-fibre ribbon core, or 2.8mm-diameter cord cables.

Seiko Instruments has added the MU and LC Angle PC (APC) Connectors to its fibre-optic product line.

Small and lightweight, they meet the demand for smaller devices to maximise use of space and reduce costs. Half the size of previous models (such as the SC), the MU Connector doubles the number of devices that can be installed on a single panel.

Minimised space consumption for input and output connections is a key factor for highly integrated units with a large number of ports, such as optical multiplexers, switches or cross-connectors. Smaller connectors enable new generations of small-form-factor transceivers supporting the increase of port density, i.e. the number of connectors fitted in a patch panel.

Both the MU and LC APC Series have an insertion loss rate of about 0.1dB (maximum 0.5dB) and a return loss rate of about 59dB (minimum 60dB) for Single Mode APC Polishing.

Designed for applications/environments requiring quick and easy termination, including LANs, WANs, intra-building, data and video transmission, SENKO Advanced Components' single- and multi-mode non-adhesive XPFit quick crimp connectors are available in FC, SC or ST styles. Termination eliminates the use of any adhesive and the need for a curing oven, and takes two minutes or less.

After assembling the connectors to the cable with the SENKO crimp tool, the fibre is cleaved and the tip of the ferrule polished to provide excellent optical and mechanical results. The connectors exceed the TIA/EIA-568-B.3 standards. They also use a high-quality zirconia ferrule and provide long-term reliability. Bend relief tubes and boots are UL rated to 94 V-0. The XPFit can also be used with standard fibre-optic epoxy.

Molex Premise Networks has added an SC version to its range of Xpress Termination connectors.

Like its ST connector, the SC version provides quick and easy fibre terminations onto a fibre anywhere (under 2 minutes, start to finish). with no ovens, power or long cure times.

Xpress Termination fibre connectors are supplied in packs of 12 including epoxy. They are terminated with a compact and low-cost tool kit, which includes all tools and consumables.

Innovative technology, originally developed by Lemo for the CERN European Organisation for Nuclear Research, has been used in the manufacture of the first sub-miniature single-fibre-optic connector.

This technology has led to the production of the Lemo Redel D Series of connectors, which offer an alternative to fibre splicing in confined areas.

Potential applications include very small-footprint simplex devices and providing fibre in the box/fibre off the board.

The Redel D features a "push-pull snap-on" fastening system which ensures a reliable and continuous connection that cannot be broken accidentally.

Other features include fully floating ferrules for improved resistance to vibration, very low insertion loss with both multi-mode and single-mode fibres and compatibility with TO-18 transmitter/emitter components.

Termination uses single standard epoxy-based techniques, and special testing is available for handling/mating.

RADIALL has introduced a new solution for hermetically sealed fibre-optic applications (as an alternative to solutions such as metallised fibre).

The hermetically sealed pig-tail is based on precise glass sealing technology, offering improved reliability and cost-effectiveness. Use of a Kovar ferrule allows easy hermetic soldering or welding on the end package.

Applications include active and passive devices, feed-throughs for MOEMS, VCSELS and other components, and any fibre-optic application requiring hermeticity. Designed for use with bare (125µm) and coated (250µm) fibres.

Corning Cable Systems' UniCam LC multi-mode and single-mode connector uses UniCam technology, which needs no epoxy or polishing. The small-form-factor (SFF) connector is ideal for higher-performance networks.

The connector is designed like a mini pigtail, incorporating a fibre stub with one end fully bonded into a ceramic ferrule and factory polished, while the other end is cleaved and located inside the connector's mechanical splice. During installation, the field fibre end is prepared, precisely cleaved and placed into the alignment of the mechanical splice. The field fibre is mated to the fibre stub and the connector cammed to complete the termination. The field fibre and stub are fully protected from environmental factors.

The UniCam LC SFF field-installable connector allows quick, easy installation and requires minimal training. It requires no epoxy or polishing.

The connector is designed and tested for compliance with FOCIS10 and ANSI/TIA/EIA-568.
