LEMO® Multi Concentric Contact Connector

A new range of products committed to setups where connectors need to allow some rotation. Similar to coaxial or triaxial connector, these precision engineered connectors include numerous concentric electrical contacts. The number of contacts range from 4 to 10 contacts available in several shell sizes. These contacts are designed for low speed rotation, can last up to 10000 rotation cycles.

These precision engineered connectors include multiple concentric electrical contacts. the number of contacts range from 4 to 10 contacts available in various shell sizes.

These contacts are designed for low speed rotation, they can last up to 10000 rotation cycles.

Unlike coaxial or triaxial connectors these connector are not impedance controlled. The contacts are recessed and scoop proof. Applications include petroleum downhole drilling systems, turret application, in other words applications where the connection may require to twist freely (instrumentation mast).

From Then to Now (and Beyond): The Advancement of Multimode Optics

Multimode optics, including multimode VCSEL-based transceivers and multimode fiber, has been dominating data center short-reach links. Why? Because they can offer:

  • Lower link costs
  • Less power consumption
  • Higher resistance to fiber misalignment and dirt at connections

There are many innovations in multimode optics on the horizon that will address several challenges, helping support and refine the appeal of multimode optics in the years to come. Let’s discuss them here.


VCSEL: The Light Source of Multimode Optics

VCSEL stands for “vertical-cavity surface-emitting laser.” Because of its moderate cost, low power consumption and ability to be manuafactured at high volume in production facilities, it is the light source used for multimode optical transmission.

A VCSEL is typically comprised of 40 to 60 layers of alternating semiconductor materials, each λ/ 4 deep; the bottom and top mirrors of the cavity are made with distributed Bragg reflectors (DBRs).


Economic Advantages of Multimode Optics

When measured to singlemode optics, multimode optics continue to be the cost-effective choice for shorter-reach data center applications. The cost of multimode fiber cable is higher than that of singlemode fiber cable, but multimode transceivers are what bring the price down:

How to Earn LEED Materials & Resources Points for Green Buildings

LEED (Leadership in Energy and Environmental Design) is an ecology-oriented building certification program run under the auspices of the U.S. Green Building Council (USGBC)

When LEED v4 was launched in 2013, many changes came along with it. One of the major adjustments, in our opinion, has to do with an overhaul of the LEED Materials & Resources credits.

LEED v3 called on project crews to source building products based on a percentage of the total cost of materials that made up the LEED building project. It focused exclusively on single product attributes (such as recycled content) and materials costs.

LEED v4 instead places urgency on the importance of product lifecycle and transparency of product ingredients. LEED Materials & Resources credits now encourage project teams to invest in products and materials that disclose lifecycle information, track environmental impacts of products and reveal the chemical ingredients used in the product. Not only does this switch to the LEED Materials & Resources credits encourage project teams to spend time seeking out environmentally responsible products, but it also benefit manufacturers that produce products with improved (and verified) lifecycle impacts.

How to Earn LEED Materials & Resources Points

To gain points in the LEED Materials & Resources category, project teams will need to source 20 qualifying products sourced from five different qualifying manufacturers. These manufacturers, and the products they produce, that have environmental product declarations (EPDs) and either health product declarations (HPDs) or material health assessments (MHAs) can contribute to LEED points.

Even if you’re not currently pursuing a LEED project, paying attention to the building products you use – including cable – offers benefits. Products that can offer LEED Materials & Resources credits ensure that:

  • Products and materials have known hazards revealed
  • Products and materials have undergone processes to document their lifecycle and environmental impacts
