SELF-PROVISIONED FIBER PLANNINGJeffrey W. Harris - Consultant
Jeffrey W. Harris – ConsultantCopyright 2015
This presentation is designed to provide information regarding some items that should be
considered when designing a self-provisioned fiber-optic network and writing the associated RFP. While this presentation contains some
information on eRate eligibility and associated rules for Self-Provisioned Fiber – Applicants are
encouraged to review the rules and, if necessary, check with a competent eRate consultant or the
SLD on such matters.

LOCATIONS TO BE SERVED
• Schools• Admin Buildings?• Internet service provider Point-of-Presence
(POP)• Other?
7Jeffrey W. Harris – ConsultantCopyright 2015
MASTER PLAN
• Even if this is only going to connect some of the buildings initially, there needs to be a master plan
• Is the district growing?• Will you ever be connecting with City, County,
Colleges or Universities in your area, an EDC?• Are there other needs to consider?

FIBER BASICS
Generally, a fiber connection consists of two strands of fiber – or a pair of fiber. For this example we are taking about a connection between the network operations center and a school.
In the example below, the red fiber strand is the transmit for the NOC and receive for the school. The blue fiber strand is receive for the NOC and transmit for the school. Together the send and receive strands represent a fiber pair.

FIBER BASICS
In the Fiber Network Topology slides that follow, I will use one green line to represent a fiber pair. So every time you see a diagram in this presentation showing a fiber connection between two buildings, the green lines represent one pair of fiber (two strands).

Just like the Partial Mesh, there are fiber runs from NOC to each school, each school has dedicated fiber strands, and ALL schools are also connected to ALL other schools

RING
PROS CONS
• No resiliency
21
• Scalable• Economical
Each school has a dedicated fiber pair from the NOC, but the same pair used for school A is also used for school E. This requires fewer fiber strands, but provides no resiliency.

DUAL RING
PROS CONS
• Slightly more expensive than Ring configuration
23
• Scalable• Economical• Resilient
Similar to Ring topology, except that each fiber pair is dedicated to a single school. This results in two data paths to the school and provides resiliency. A cut anywhere on the ring will NOT result in loss of connectivity to any school.

INSTALLATION METHOD
• Aerial – Hung from existing poles or on customer-owned poles
24Jeffrey W. Harris – ConsultantCopyright 2015 Photo courtesy of The Fiber Optic Association, Inc.
INSTALLATION METHOD
• Buried – Installed into an open trench, either directly buried or inside of one or more conduits
25Jeffrey W. Harris – ConsultantCopyright 2015

INSTALLATION METHOD• Directional Boring – Conduit is installed using boring
equipment with minimal surface disruption and fiber is pulled through the conduits

• Total cost +/- $2m
QUESTIONS
28Jeffrey W. Harris – ConsultantCopyright 2015
RIGHT-OF-WAY
• You will need permission to install in an existing right-of-way, or will need to acquire easement(s)
• Even if you use aerial fiber, you will need permission to attach your fiber to existing poles, or will need to acquire easements to install your own poles
• Special circumstances will require additional permissions:• Attaching to bridges, • Crossing RR lines• Crossing or running along the side of state/federal roadways• Crossing Irrigation District pipelines• Others
• Who will be acquiring access and filing for permits?
29Jeffrey W. Harris – ConsultantCopyright 2015
CONSTRUCTION DETAILS
• How deep will you want your buried or bored installations?
• Do you need marking tape for buried installations?• What type of conduit will you specify for buried and/or
bored installations?• Will you require conduit testing prior to fiber installation?• Will you require pull strings?• Will you be providing splicing details (especially
important if this is an add-on)• Will you require signage for conduits and Manholes?
30Jeffrey W. Harris – ConsultantCopyright 2015
CONSTRUCTION DETAILS
Building entrance –• Is there an existing cable entrance vault?• Will you accept PVC or require Rigid pipe?• Where will you transition from outdoor to indoor
fiber?• Does your inside cable need to be plenum rated?• Where will the fiber terminate?• Who is providing the LIU?• What type of termination is required?
31Jeffrey W. Harris – ConsultantCopyright 2015
FIBER-OPTIC CABLE
• What type of fiber do you need?(method of installation and modulating equipment will dictate to some degree)
• How many strands will you need for each location?
• Will you be installing spare strands?
• What are your tolerances for splices and terminations?
• Based on distances, splices, future repairs and hardware specifications– will the anticipated dB loss be within tolerance?
• What tests will you require be conducted on the fiber?
32Jeffrey W. Harris – ConsultantCopyright 2015
MAINTENANCE AND OPERATIONS
• How will fiber-cuts be handled?
• Will 1st year maintenance be included in the RFP?
• Who will conduct your fiber locates?
• How will your signage be maintained?

PROJECT BIDDING• For self provisioned RFPs, or Dark Fiber RFPs, you are required to also bid lit
leased service
• The RFP needs to be detailed (per USAC)
• Vendors will need more sufficient time to understand your needs and put together a proposal – probably more than the required 28 days
• In order to obtain funding for self-provisioned fiber, it must be cost effective
• How many years will you use for the comparison?
• You will need to extrapolate bandwidth needs across that time frame and estimate the cost over your selected term
• Your comparison to lit leased service needs to be Apples-to-Apples across your timeframe
34Jeffrey W. Harris – ConsultantCopyright 2015
NETWORK EQUIPMENT
• Do you currently have a Wide Area Network -OR- are your schools each being serviced directly by your Internet service provider?
• Does each location already have equipment in place capable of lighting the fiber?
• Will you be connecting at 1Gbps? 10Gbps? 40Gbps? 100Gbps? and will your existing equipment be able to handle it?
• Do you already have the correct equipment including blades and modules?
• Are you considering DWDM? And if so, will your current equipment be able to handle it? Will the fiber you have specified handle it?
• If you don’t already have the proper hardware and modules, you will need to include the appropriate components in your RFP so that you can conduct an adequate comparison to the lit leased fiber solution
• The hardware you have or that you select may affect your fiber-strand counts
35Jeffrey W. Harris – ConsultantCopyright 2015
RULE CHANGES
Old Rule• Special Construction
Costs over $500,000 were spread out over 3 years
• District up-front share had to be paid the first year
36Jeffrey W. Harris – ConsultantCopyright 2015
New Rule• Special Construction
Costs can be paid the first year
• District up-front cost can be amortized over up to 4 years
RULE CHANGES
Old Rule• eRate would only pay
Special Construction Costs up to the Applicant’s property line
• Modulating electronics to light the fiber were not eligible as Category 1 Service
37Jeffrey W. Harris – ConsultantCopyright 2015
New Rule• eRate will pay Special
Construction Costs to wherever the fiber needs to be laid
• Modulating electronics to light the fiber ARE eligible as Category 1 Service

CONCLUSION
There is a lot to consider when you write this RFP. Any detail that you leave out will:• increase the number of questions you will
receive from vendors, • slow down your bid process (possibly causing
you to issue an extension), and • increase the complexity of evaluating the
responses.
48Jeffrey W. Harris – ConsultantCopyright 2015
CONCLUSION
In the end this will be YOUR fiber…
Don’t you owe it to yourself, the teachers, and the students to make sure it is done right?
