What is a OD OD is basically 5 racks of equipment T, Forward & Return Optics and associated RF splitting combining feeding X number of fiber deep nodes. Nodes served from a OD varies depending on vendor T port/service group capacity and H density isco cbr 56 /G s OD = 22 to 20 nodes Arris E6000 /G s OD = 192 to 22 nodes Driver for OD architecture tandardized architecture peed deployment process by racking, configuration built off-site then shipped onsite for final assembly Repeatable staging process leads to consistent installations and reduced time on-site 201 isco and/or its affiliates.
