Collocated Port Networks
For a standard reliability system with 1 c ollocated EPN, use 1 fiber optic cable
and 2 lightwave transceiv ers to directly connect the networks.
For a standard reliability system with 2 colloc ated EPNs, use 3 fiber optic ca bles
and 6 lightwave transceiv ers to directly connect the networks.
NOTE:
Based on floor-plan consi derations, the length of these cab les may vary.
20 foot (6.1 m) cables are normally ad equate for a Release 8 with 2 port
networks.
For collocated cab inets, route the fiber optic c ables directly from the PPN to the
EPN cabinet. If a “ DEFINITY style” PPN cabinet is colloc ated with another
“DEFINITY style” EPN cabinet, the preferred routing is to run the cab les
up
the
cable tray and out the top of the PPN cabinet. The cables are then run to the
other cabinet, through the top of the cabinet, and d own the cable tray to the
desired carrier level.
If a “DEFINITY style” PPN cabinet is collocated with either a small cabinet,
medium cabinet, or sing le-carrier cabinet s tack, the preferred routing is t o run the
cables
down
the cable tray and out the b ottom of the PPN cabinet. The cables
are then run to the EPN cabinet and up the outsid e of the rear panels to the
desired carrier level.
Fiber-Remoted Port Networks
For a standard reliability system with 1 fib er-remoted EPN, use 2 fiber optic
cables, 2 lightwave trans ceivers, and 2 lightg uide interconnect units (p rovided
by the PSC).
For a standard reliability system with 2 fib er-remoted EPNs, use 6 fiber optic
cables, 6 lightwave trans ceivers, and 6 lightg uide interconnect units (p rovided
by the PSC).
For fiber-remoted cabinets, route the c ables down the cab le tray and out the
bottom of the cabinet to the M DF where the lightguide interconnec t units are
located.
In either case, use cable tie s to secure the cable agai nst the walls of the cable
tray at the cable tie positions built into the trays.
