Dark fiber ring
• Discussions with vendors have identified key questions and issues
• Should the COE use the consortium to bid for the dark fiber ring(s) and
equipment?
• How does COE estimate cost for districts to consider the solution?
• The cost of the dark fiber equipment
• Dark fiber construction RFP being finalized
• The purpose is to “test the waters”
• Example requirements
• Provide pricing for individual segments between nodes (district
office sites)
• Provide various pricing models for proposed rings
• Lowest cost
• Most sites which can be included
• Optimal ring configuation for future expansion

• Multiple traffic channels on a fiber pair
• Each channel transmitted on a different wavelength/color prevents channel interference and allows them to
be separated at the receiving end

Amplifier(s)
• Client – The source of the signal requiring transport
• Transponder/Muxponder/Xponder – Converts short reach MM or SM client laser to DWDM. Not necessary when
using client-based DWDM pluggable optics
• Multiplexer/Demultiplexer – Passive device which multiplexes (and demultiplexes) multiple DWDM wavelengths
to/from the fiber
• ROADM – Wavelength Add/Drop and Multi-Directional Switching
• Amplifier – needed depending upon distance/loss

Firewall services
Barracuda NG Firewall
• Barracuda NG firewall with Security Suite has been
discontinued
• Multi-tenancy model is no longer supported
• Stand-alone NG Firewall continues to be offered
• SCCOE will not be utilizing Barracuda to offer firewall
services
Palo Alto Networks
• SCCOE has put a bid out for a
PA-7050
• 3 network processing cards (NPC)
• NPC option 1: 2x40 Gig QSFP,
12x10 Gig SFP+
• All district connections will be
consolidated to PA-7050
• UI and administration will
remain the same
• Migration and customer training
challenges factored into decision
to remain with Palo Alto
Palo Alto Networks
• Cut-over will be scheduled
and coordinated with districts
• New platform will allow for
additional customers to
leverage firewall services
Palo Alto Networks
• SCCOE is reviewing the price
structure for firewall services
• Update likely to be based upon a
tiered service model
• Palo Alto Networks has invited
COE and school districts to a
half-day technology briefing at
the HQ Executive Briefing Center
• Agenda will include technology
overview, roadmap and best
practices
• Date to be determined, likely
middle to late March timeframe
