  1. Lighting The Fiber‘The Road to an Operational RON’ j.p.streck (NC State/NCNI/NCLR) m.johnson (MCNC/NCNI/NCLR)

  2. What I learned this summer: • It will be necessary to rely on your vendor more than netheads are used to doing • Flexibility is good. Build this in from the start. • SONET is good. You will figure that out eventually (why the telcos loved it). • Your optical network will require a different approach to maintenance and spares - unless you have way more money than we do. • Everything you touch will require you to touch everything else. • My provider didn’t tell me THAT

  3. My provider didn’t tell me THAT • Mfgr specs • Find out from provider(s) exact type(s) of ALL fiber • What are the real numbers • (do the engineering due diligence) • Loss (always important) • Measure it yourself. Don’t rely on provider’s numbers. They may be calculated (as opposed to measured) or old. • Dispersion (increasingly important as distance/bw/waves increase) • Topology, in particular Route Diversity • Understand the hand hold, hut and PoPs • Understand power capabilities

  4. RFI & RFP process • Read the vendor spec • Consult a photonics engineer • Consult RONs that have done current installs • Develop your optimum specs list with parameter priorities for the RFI process • Initiate the RFI cycle (all or subset of vendors) • Distill RFI results • Convert RFI spec into an RFP spec • Initiate the RFP cycle • Pick a vendor / integrator

  5. Refine the BOM prior to cutting the Purchase Order • Confirmation of fiber plant optical characteristics • Vendor engineering • Hired fiber engineering co. • Run vendor planning tool with confirmed • optical measurements • Pick terminal, OADM & Regeneration sites • Ring layouts • Linear layouts • After sticker shock, readjust Bill of Materials (BOM)

  6. Experiences NCNI/NCLR • Past history of fiber & equipment • Three plus fiber providers • Two different regional rings (110+ miles) • One SONET BLSR ring • Three generations of DWDM networks • Lucent 40G • Nortel Optera (first generation) • Cisco ONS-15454

  7. Experiences (cont.) • Installation process • SONET most difficult and time consuming • New Photonics and Mgmt tools greatly simplifying the install-turn up-data passing cycle • OAMP • Must have a robust but easy to use NMS • A small list of unique parts list is a MUST! (keep inventory to a minimum) • Amps • Transponders (unique lamba cards) • Filters (mux-demux) • Client side • Always easier to cool down a interface than to boost the signal
