SystemSupportSolutions distributes MRV Communications FastE / GigE Free-Space Optics link equipment, and can be a valuable partner for your point-to-point link project. For a quick tour of the various available MRV link models, you can visit the model listings by clicking the model name above that matches your link distance.

Optical Wireless equipment implementations must be optimized as to correct technology, and model. Each link's unique parameters need to be considered:

  • Precise link distance
  • Usage (data - voice - video) (primary link - redundant link - disaster recovery link)
  • Speed (T1/E1 - 10Mbps - 100Mbps - 155Mbps - 622Mbps - 1.25Gbps - 10Gbps)
  • Protocol(s) to be supported
  • Availability required
  • Auto-failover implementations
  • Rigidity of the installation environment

Consequently, we draw from MRV's large and highly granular selection of models when making a recommendation for a specific application.

To really "zero in" on your specific deployment, we will help you do a Site Survey.

 

Appropriate Link model selection...

TS700case

Appropriate model selection is important for optimal link performance and availability.

SystemSupportSolutions can be helpful to you in selecting your link as well as designing and/or implementing a valid installation. The greatest potential for errors are wrong model, wrong mounting...

1. Wrong model.

One reason the FastE/GigE link industry doesn't have tens of thousands of raving supporters is that specific solutions tend to be deployed in the general absence of clearly defined performance criteria. Worse yet, in the unusual circumstance where good performance criteria are specified, manufacturers are free to develop their equipment specifications in a standards vacuum. Case in point: allowance for mis-pointing when developing distance ratings. Some deduct link margin assuming non-active aimed equipment will, on average, suffer some mis-pointing. Others do not. So, on a strictly black-and-white basis you can end up spending more money for less link margin.

 

On a simpler level, for any given link specification, there are always a number of models that meet or exceed the requirement. For example, a Fast Ethernet FSO link at 100 meters could be deployed with ANY of the currently available Fast Ethernet FSO models in existence. But using a $33,000 4,000-meter link would not be an optimal choice when a $4,500 400-meter link would do the job. This would be a case of unnecessarily expensive model selection. In fact the $33,000 link would probably saturate at that short distance and perform poorly. It would also exhibit "hair-trigger" alignment issues due to its low beam divergence which in part is what gives it its long distance capabilities.

Conversely, the opposite case can also cause problems: the deployment of a link that minimally complies with the performance requirement, but is really on the edge of its capability will provide less than satisfactory availability over the long term.

Add to these types of model selection issues the fact that the various manufacturers each seem to "hit" specific link requirements squarely, but miss others and you begin to see why SystemSupportSolutions as a highly specialized FastE/GigE FSO Distributor can be helpful to you in your wireless link projects. 

 

2. Poor physical mounting.

In SystemSupportSolutions' nine years of link deployment experience, we have learned that a good physical installation is crucial to satisfactory link performance over time. What seems "good enough" just isn't in many cases. When it comes to selection of mount locations on structures, the mounting systems themselves, and actual workmanship on installation of the mounting system, there is really no substitute for experience. And the up-front cost difference between a suitable mount and a poor one is usually little to none. 

The school of hard knocks seems to be about the only real "distillation-source" forBridgewave testing avoidance of the unexpected when it comes to link deployment.

For a Free-Space Optics link, The flag that when dropped to half mast in a NW breeze blocks the beam path. Or the seemingly rigid masonry wall that spans too great a horizontal length without a supporting perpendicular wall or corner, and expands excessively in direct sun mis-pointing the link. A tree that grows into the beam because of inadequate clearance. Or a delivery truck that sticks up higher than planned for in the parking lot between the transceivers.

These and lots more all can become issues. We have made enough of the mistakes in our 400 or so deployments, that we can pretty much eliminate them for you.

3. And backing up to first base, the only valid basis for a good physical installation is a thorough Site Survey

A Site Survey, which could also be called a comprehensive installation plan. It can really only be performed with the assistance of someone experienced in link deployment and installation and certified by one or more of the manufacturers. Alternatively, all of the critical site data can be easily accumulated by any competent technician on site, and then submitted for compilation to a manufacturer certified technician. SystemSupportSolutions provides both types of Site Survey projects, the latter process (a Virtual Site Survey) saving travel costs outside the Twin Cities, Minnesota region.
