Extreme data centres are submerging their servers in tanks of liquid coolant, and Molex is working on a way to get optical fibre signals in and out of those tanks – particularly two-phase tanks, where vapour sits over the liquid surface. Branding them VaporConnect optical feed-through modules, the company said that they are a cassette-based design that bolts directly onto ...

TiniFiber is making pre-terminated MPO (multi-fiber push on) cable assemblies from its’ Micro Armor’ optical fibre cable. The cable “assemblies are tested and verified to meet standards including IEC 61754-7 and EIA/TIA-604-5 (FOCIS 5), which specify a connector’s physical attributes as well as performance, and ensure inter-mating across all complying cables and connectors”, according to the company. Armour in the ...

ODU has added its EBP (expanded beam performance) optical connection technology into its Mini-Snap Series K, Medi-Snap, ODU-Mac product ranges. “As a non-contact lens technology, EBP achieves low attenuation, virtually no cleaning or maintenance requirements and a long service life,” claimed the company, which explained: “Under normal conditions no maintenance is required  – cleaning the ferrule is only necessary in ...

402Tbit/s has been sent down 50km of commercial-grade optical fibre by an international team led by the Japanese National Institute of Information and Communications Technology (NICT). 1,505 WDM (wavelength division multiplexed) channels were used simultaneously, spread across six optical bands spanning 37.6THz (275nm) of spectrum. Signals were boosted with six doped-fiber amplifiers, with lumped and distributed Raman-amplification, “to cover all ...

Cinch Connectivity Solutions has announced a 100Gbit/s optical transceiver, intended for tough environments including aerospace, industrial and military. H28-100G-SR4 has four transmit and four receive channels, each rated at 25.78Gbit/s. For ease of installation and replacement, the package has a square array of flat pads underneath and it mounts to a similar array on the associated PCB via a guide ...

Corning has created an optical fibre connector system that aligns 12 fibres in a single operation to bring data to homes. “Multifiber Pushlok is a ‘stick-and-click’ [that] allows operators to deploy more fiber in tighter spaces,” according to the company. It takes “complicated splicing tasks out of the field to help installers connect homes and businesses”. The technology has been ...

University of Sheffield spin-out Phlux has announced its first product, a family of 1,550nm avalanche photodiodes. Called Aura, the infra-red devices are built using antimony alloy modified InGaAs. “The resulting sensors can be operated with APD gains up to 120, enabling even the smallest signals above the noise floor of a connected trans-impedance amplifier to be amplified,” according to the ...

OMC has developed LEDs able to couple visible wavelengths into 1mm core polymer optical fibre, or 200 micron or larger glass optical fibre. “This latest product is suitable for laboratory equipment for research purposes, test and measurement instrumentation, and data communications in industrial and medical applications,” it said. They were initially developed as a custom product for a research which ...

Route planning has started on the pan-Arctic submarine cable that could link Europe, North America and Asia via the Northwest Passage – the latter opening as formerly permanent ice yields to climate change. The idea of the project, dubbed Far North Fiber, is to terminate in Japan, Norway and Ireland, and have branches to Alaska, Canada and Greenland (see map). ...
