Direct Manufacturer Fibre Reference Guidelines
PrefaceINTRODUCTION AND PURPOSEDEFINITIONS AND ABBREVIATIONSRoute distance is commonly used to describe a fibre network, although, it is not always an easy calculation to make. Fibre optic cable is comprised of a glass strand about the size of a hair over which lasers transmit light in different wavelengths to provide communications services. Through these cables large amounts of data can safely and securely be transmitted over long distances.Start with a map and a plan showing how you will move ahead with fibre connectivity in the organization. A good design sets a good path. PRELIMINARIESSCOPE ORGANIZATIONAL SUPPORTThere are many ways that a fibre network could be constructed, and these range from capital build projects to using abandoned ducts, partnerships or a combination of options to achieve the desired goal.CAPITAL BUDGETSNEW DEVELOPMENT UTILITY UPGRADES AND DIG ONCE POLICYAdvocate for the organization to adopt Dig Once. This policy has many advantages, including cost saving and minimization of impact to roadways. ABANDONED DUCTSWater and sewer mains and gas pipes are the most common abandoned ducts. An inspection is required to determine how usable the pipes will be and the cost to make it suitable for communications cabling. Partnering agreements with other organizations can greatly reduce costs for all parties involved.During partnership negotiations it may be possible to include upgrading of ducts and vaults as part of the fibre deal that may have been damaged or crushed in the past and are otherwise unusable. CHALLENGESORGANIZATION OWNERSHIP AND FUNDINGROW MANAGEMENTFAIR DEALSSTANDARDSENGINEERING STANDARDSOrganizations should have standards for privacy and security related matters, which should be developed prior to the expansion of a network or partnership deals if none are in place. COST ESTIMATES VALUING THE ASSETThe reliability of the network is crucial to provide a valuable service for the organization and partners. RISK MITIGATIONThere is the ability to build diversity into the network and make it more secure in the event of a minor or major disaster. The risk in owning a fibre network is mitigated by the advantages the network affords the organization in times of disaster. REDUNDANCY FOLDED RING INFORMING THE ORGANIZATION SUPPORT STRUCTURE AGREEMENTS (SSAS)CANADIAN RADIO-TELEVISION AND TELECOMMUNICATIONS COMMISSION DARK FIBRE Several types of maps should be used for a fibre network, including high level routing maps, civil permit drawings, engineering drawings and splicing finger diagrams. MAPPINGEngineering drawings and scope of work documents are important for companies to bid on any projects or perform easier installations.
