Pages 71 and 83 are the basis for this example which is slightly modified to add a voice connection at every outlet and a phone in the telecommunications room (every job has changes). In this scenario, an animation studio is leasing this space and will require high data rates to accommodate frequent transfer of large computer generated imagery (CGI) files.
Thirteen outlets will carry four Category 6A cables (one data/one voice/two for growth) and one two-fiber cable. All desktops support 10 Gb/s.
Cable types and count
The distances involved in this example are under 90 meters, so the 10 Gb/s horizontal links are supported by Category 6A twisted pair cable. For future growth, each desktop has two additional twisted pair cables and one fiber optic pair. Cable the voice network with Category 6A twisted pair cable. The hung ceiling is not a plenum space, so riser-rated cable may be used (although this recommendation may be superseded by local codes).
Cable routing and amount
Place the conveyance as shown. Calculate cable length by taking the measured distance (taking a right-angled route) PLUS three meters for the ceiling-to-outlet drop and termination slack PLUS the length of the tray in the telecommunications room PLUS three meters for ceiling-to-floor in the telecommunications room. The orange line shown is 25 meters (82 feet). Remember to add 10% to the total cable length. Install cable in the tray; use J-hooks to support cables to the outlets. While the cables may be pulled separately, bundled or hybrid cables will speed the installation.
Termination considerations
Thirteen outlets times three data U/UTP equals 39 patch ports. Since growth is already figured in with the extra U/UTPs, a 48 port patch should be sufficient. Thirteen voice circuits times two is 26; a 24 port panel should work.
Thirteen fiber pairs times two is 52 fibers, so a 48 port panel should be large enough.

Distributed Backbone Segment
Page 73 is the basis for this example page which connects five telecommunications rooms to an equipment room. All TRs have active equipment for transmitting signals to the intermediate or main crossconnects. The first four floors have 100 Mb/s to 1 Gb/s connections; the fifth floor has a full 1 Gb/s to the desktop and 10 Gb/s to the equipment room. The voice signals travel on their own network with each voice circuit carried to the equipment room by 25 pair Category 5e cabling (six U/UTP per cable). Each story is 4.6 meters (15 feet) tall making the longest cable about 36 meters (118 feet) in length.
Cable types and count
LazrSPEED® 300 multimode fiber works well over these speeds and distances. CommScope recommends using a riser-rated hybrid cable with 6 TeraSPEED® single-mode fibers and 12 LazrSPEED 300 fibers. This may seem excessive, especially for floors 2 and 3. However, it provides ample capacity for growth while simplifying the purchasing process (only one type of cable to order). Remember to check local codes for confirmation of cable listing.
Cable routing and amount
For this example, take the height of the story and add five meters at each end for termination slack PLUS another three meters for the service loop. The top floor link requires 23 + 5 + 5 + 3 or 36 meters (about 118 feet) of cable. Remember to add another 10% (3 meters [10 feet]) to the total cable length. Subtract 4.6 meters for each lower floor link.
Termination considerations
Use connectorized patch cords to connect the patch panel to the active equipment.

Collapsed Backbone Segment
This example is similar to page 170 except that collapsed backbones connect all the floors through patch panels in the telecommunication rooms. The voice signals travel on their own network with each voice circuit carried to the equipment room by 25 pair Category 5e cabling (six U/UTP per cable). Each story is 4.6 meters (15 feet) tall making the longest cable about 36 meters (118 feet) in length.
A collapsed backbone is defined as a continuous link from the desktop to the equipment room.
For flexibility the link will be patched in the telecommunications room. In this example, plenum horizontal cables are connectorized and patched to riser-rated cables.
Cable types and count
Using a riser-rated cable with 72 LazrSPEED 300 50 µm multimode fibers is recommended (additional single-mode fiber is not needed for these speeds and short distances). This much fiber may seem excessive, especially for floors 1 - 3. However, it provides ample capacity for growth while simplifying the purchasing process (only one type of cable to order). Remember to check local codes before ordering cable.

For this example, take the height of the story and add five meters at each end for termination slack PLUS another three meters for the service loop.

Fiber to the Enclosure
In this example, a factory has sales offices on the second floor and a management suite on the third floor. Since the third floor has a relatively small population of twenty desktops and is located over 100 cabled meters from the second floor telecommunications room, the best combination of cost and performance is to serve the area with a fiber enclosure (FTTE) with active electronics and a patch panel. (NOTE: depending on the type and speed of the network, the suite may be served by a twisted pair, fiber or wireless technologies.)
Cable types and count
Because the cable will be conveyed through the ceiling, a plenum-rated LazrSPEED multimode fiber cable (preferably but not necessarily unspliced) should be used to connect the enclosure to the equipment room. FTTE is designed to take advantage of the lower cost, small port count switches, so only two fibers for every 8 or 12 ports are required, adding a minimum of two additional fibers for redundancy and growth.
Cable routing and amount
The cable will be conveyed by cable ladders in a plenum space. The horizontal distance is 100 meters, with two riser transitions of one story (4 meters) PLUS 3 meters to reach and enter the enclosure PLUS the equipment room’s diagonal-plus-three-meters slack PLUS three meters for ceiling-to-floor in the equipment room. Remember to add 10% to the total cable length.
Termination considerations
The fiber cable should be connectorized at both ends with the connector system of choice.

Small Campus Backbone Segment
In this example, the equipment room at a corporate headquarters is connected to a factory 200 meters away. Terrain considerations (in this case, a stream) indicates the use of messengered aerial cable. Traffic speeds of 10 Gb/s can be handled over this distance by all-dry loose tube LazrSPEED 300 multimode fiber pairs (with TeraSPEED single-mode fiber installed alongside them for future growth). The connection to the local access vault is an underground single-mode optical cable.
Cable types and count
LazrSPEED 300 fiber works well at this speed and distance. An armored messengered outside plant loose tube cable with six 50 μm high-bandwidth LazrSPEED 300 fibers can handle present campus backbone needs. Six more fibers should be added for future considerations.
Another six TeraSPEED fibers should be installed as well. The cable to the local access vault is an outside plant loose tube TeraSPEED cable. Furcation kits will be required.
Cable routing and amount
Messengered cable needs support about every 100 meters (330 feet) so a pole or two needs to be erected along the right of way. The ‘distance-plus-10%’ rule applies for calculating the amount of cable, but be sure to factor in the distance from the building attachment points to the equipment rooms and any elevation changes (if MC is 60 meters higher than IC 1, then using a2 + b2 = c2 shows the cabled distance to be 209 meters) plus equipment room drop and slack.
Termination considerations
The cables terminate at entrance facilities and will be mechanically or fusion spliced to pigtails.
