General Information:

 

·        Concrete building.

·        The building is 3 stories.

·        The Link head transceiver will be located on the East side wall of the penthouse

·        Please see visuals for exact mounting location

 

Line of site:

 

·        See "Site A" LOS

·        An issue exists at this end of the link involving the sun. Because the orientation of the transceivers is east to west, there will be approximately 2 days/year when the disk of the sun could align directly behind the site B mount location. This can compromise the link for up to 5 minutes. Ordinarily, the mount would be lowered so that the sidewall will provide shielding from the sun. In this installation that is not recommended for two reasons:

1. The LOS is only clearing trees by 10'

2. A redundant RF link is present and will keep the link functional during these brief incidents

If remote management or video monitoring is desired, add additional cables.

 

 

Equipment:

 

·        Type of unit                                  Link head XXXXX

·        Communication protocol            Fast Ethernet

·        Fiber center wavelength 1310nm

·        Host Network                               10/100 Ethernet Switch

·        Data Rate                                    100Mbps

 

 

Purpose:

 

This installation will be used to connect buildings at (Site A) and (Site B) for data communications.

 

 Pre-Installation requirements:

 

·        Installation requires that a small junction box be installed close to the mounting location, 1 to 2 feet to the right or left.

·        This junction box should contain the AC power outlets and room for the fiber optic cable terminations

·        The Link head transceivers have an electronics box with openings for ¾” flex conduit, ¾” flex conduit should be used to route power and fiber from the junction box to the Link head transceiver.

·        Alternatively, the user can install a shrouded outdoor power outlet where the unit can be plugged in and use ¾” flex conduit to route the fiber connection into the unit.

·        The Link head transceivers use 62.5/125-micron multi mode fiber with a center wavelength of 1310nm to 850nm, terminated with ST connectors, to connect to the clients network.

·        The center frequency depends on the type of networking equipment used and must be specified by the user, prior to shipment of the Link head equipment.

·        A minimum of two strands of fiber is required for connectivity.   It is recommended that six strands of fiber be installed.  Two for connectivity and the remaining four for redundancy and remote monitoring if purchased.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Visuals:

 

The Site A link head position is located on the rooftop of a three-story brick office building located at Street Address in City, State. The building is part of the larger complex and is known as Building II. The mount will attach to the sidewall and will provide a transceiver position approximately 42" above the parapet cap.

This is the view from the installation location on the south west corner of the rooftop of site A looking west toward the rooftop of site B. The Link head will be located on west side approximately six to eight feet N of the south west corner of the building's penthouse sidewall. The corner provides good rigidity and a good line-of-site position. If permission is granted, the vertical flange will attach to the inside of the parapet sidewall.

This picture was taken from a position 2' above the parapet.

 

 

The Site B Link head position is located on the sidewall of the penthouse of the Building Name, a three-story brick office building located at Street Address, City, State; 656 meters west of site A.

 

 

 

 

The mount will position the transceiver 42" above the parapet cap.

 

The side of the penthouse parapet at the Site B building provides a solid brick surface for a rigid mount.

This zoom of Site A from Site B discloses the beam's clearance over the treetops. There is currently approximately 10' which is a good margin allowing for a couple of years or more of growth.

This is the view from the installation location on the east side of the penthouse of site B looking east toward the rooftop of site A. This picture was taken from a position 2' above the parapet.

 

 

Conclusion: 

 

The procedure envisioned for this installation is that FSO Contractor Name will accomplish the installation including cabling, mounting of the equipment, positioning, calibration of the transceivers, and configuration of the OptiSwitch 400 for failover to the existing BreezeCom 2.4 Ghz RF link. Company will provide lightening protected 110vac at the two equipment installation points on the two rooftops.
