Optical Lan Solution

Simplifying Enterprise Passive Optical Networks (PON)

As optical fi ber moves closer to end users, rapid changes are underway  in both the data center and the equipment closet. As a result, new installation and maintenance techniques are being employed within enterprise applications. Passive Optical Network (PON) applications are now being deployed. Fiber is no longer limited to just access equipment. Fiber connectivity to a single user is a reality. TE Connectivity off ers complete, end-to-end PON infrastructure solutions called Optical LAN Solution (OLS). From the data center to the desktop, our customers have tapped the experience and innovation of TE to build their PON networks. TE’s suite of end-to-end connectivity solutions is truly comprehensive. This ordering guide highlights the most commonly used components that feature fi eld-proven attributes that can save time, money and help improve customer satisfaction. The diagram below highlights a PON deployment using one of the TE OLS solutions. Each number corresponds to a specifi c innovative TE
product which is described in more detail in this ordering guide.

Cat8/Category 8

What is Cat 8?
Currently there are a number of similar but different Category 8 (Cat 8) solutions being considered by the standards bodies for 40Gb/s over twisted pair copper.

In the USA, TIA/EIA is considering Cat 8 based on an extended performance Cat 6A cable. Meanwhile in Europe ISO/IEC is looking at two options currently tagged Cat 8.1 based on an extended performance Cat 6A cable and Cat 8.2 based on an extended Cat 7A cable. Interestingly all of these are based on shielded cables and connectors because of alien crosstalk difficulties.

As yet, there is no clear choice of connector – though there is a significant body of weight in favor of the RJ-45 footprint rather than the larger ‘square’ contender. This is partly in order to achieve high density patch panel and switch configurations and partly because RJ-45 is what almost everyone in the industry is used to and comfortable with.

It looks likely however, that even if a RJ-45 profile jack is used, to ensure the necessary crosstalk performance, its pin configuration will mean that it will not be backward compatible with 10GBASE-T and lower speed standards. Whilst this is unlikely to create a problem in the data centre, it might not be so acceptable if Cat 8 ever reaches the enterprise LAN.

Thermal Adhesive Coated (TAC) Fiber System

TE Connectivity’s (TE) thermal adhesive coated (TAC) fiber system provides fast, flexible and nearly invisible installation of fiber cable within a home or business.

Utilizing a lightweight, portable handheld fiber tool and 900 micron fiber microcable with integrated adhesive, installers are able to quickly and easily install fiber around baseboard, windows and trim work.

When turned on, the handheld device triggers the heat-activated adhesive in the fiber – allowing the fiber to bond continously to the surface area as it is applied.

Benefits

  • Fiber bonds consistently to common surface types in any indoor environment
  • Does not require messy caulking, staples or brackets
  • Installed cable almost undetectable to the casual observer
  • Reduced bend radius fiber technology is less susceptible to attenuation loss as a result of handling and tight bends
  • Microcable compatible with field installable connectors, or can be fusion spliced into the network
  • Cordless, portable – fiber dispenser tool travels anywhere

Features

  • Microcable fiber adheres to surface with heat activation
  • Ergonomic, battery-operated handheld fiber dispenser tool
  • Removable sleeve on handheld device enables quick disengagement of fiber cable
  • Available in 300, 500 and 1000 foot cable spools
