The rack should use the universal mounting rail hole pattern identified in IEC Standard 297. The rack should be made of steel. The rack should support approximately 272 kilograms (600 pounds).
Page 109: Cabling Requirements
Installing New Cabling ATM Cabling Ethernet Cabling 3Com recommends that you use a cabling system plan, such as AT&T's Premises Distribution System (PDS) or the IBM Cabling System. Determine how many CoreBuilder 7000 units are going to be supported by each wiring closet, and how many downlink connections from these CoreBuilder 7000 units are planned.
Page 110: Atm Cabling
Assign a unique identification number to each distribution rack. Make all work areas and wiring closets easy to identify by labeling the front panel of the CoreBuilder 7000 and other hardware and by displaying the floor location grid and cabling plan in each wiring closet.

(1) single mode fiber (short reach) (SMF-PMD). When deciding whether to use multi-mode or single mode fiber, determine the maximum interstation distance (the distance from the CoreBuilder 7000 to any potential end station): Fiber optic transceivers are sensitive optical devices that need careful...
Page 112: Multi-Mode Fiber Standards
Compare the specifications of the fiber you are using to those in the following tables. If the fiber does not meet the specifications, use a different fiber or contact 3Com's Technical Support. The fiber you use must meet the specifications listed in Table 25, which describes the standard set forth in MMF-PMD.
Page 113: Calculating Insertion Losses For Unlike Fibers
Table 25 Standard Multi-mode Fiber Specification (continued) Maximum distance between nodes Output power (from transmitter) Receive power *Maximum attenuation includes cable attenuation and the loss induced by other components such as connectors, splices, and the mating of unlike fiber types. Although some 2 km cable plants have a total attenuation of less than 11.0 dB, the 2 km interstation distance must be maintained to comply with modal bandwidth requirements.
Page 114 ST connector (ceramic) ST connector (plastic) ST connector (stainless steel) 62.5/125 cable 8/125 cable Bypass switch (currently not available in single mode) Fusion splice Example Suppose that a link consisting of one km of 62.5/125 fiber with a maximum attenuation rating of 1.75 dB/km is transmitting into one km of 50/125 fiber with a maximum attenuation rating of 3 dB/km.
Page 115: Verifying Modal Bandwidth
Because the resulting value, 7.85, does not exceed the maximum attenuation value, no adjustments are needed in the types of fibers joined or how they are connected. The link meets all of the specifications of the MMF-PMD. The bandwidth of an optical fiber is the lowest frequency where the Verifying Modal magnitude of the baseband frequency response has decreased by 3 dB Bandwidth...
Page 116: Comparing Fiber To Specifications
Category 1 and Category 2. These categories refer to the optical power that must be launched into the fiber by the transmitter or detected by the receiver. 3Com currently supports only Category 1 single mode fiber. The specifications for the standard single mode fiber are listed in Table 29.
Page 117 Table 29 Single Mode Fiber Specifications (continued) Category 1 Output power (from transmitter) Receive power Maximum distance* between ATM devices Maximum attenuation** Category 2*** Output power (from transmitter) Receive power Maximum distance* between nodes Maximum attenuation** * Maximum distances assume cable with one splice every 2.2 km with 0.3 dB loss each, and with no patch panels or mechanical splices.
Page 118: Verifying Maximum Attenuation For Mixed Fibers
Example. If a Category 2 transmitter is outputting to a Category 1 receiver, the maximum attenuation is 26.0. Connect the CoreBuilder 7000 DS-3 interface by a 75 Ohm coaxial cable DS-3 Coax Cables that complies with DS-3 standards. The maximum cable length is 450 feet.
