OC-3 Connection
An OC-3 carries 155 Mbps on SONET, and that heritage is most of its cost. Where Ethernet or a wavelength can serve the same requirement, they usually price better per megabit, so an OC-3 quote should never be read alone.
What actually sets your OC-3 rate
Putting your OC-3 out to bid
- 1Post the requirement once. Address, bandwidth, sites, and the date you need it live. That is enough for carriers to price.
- 2Carriers that reach you bid against each other. They know they are in a competitive bid, which is the single biggest reason a first number comes in lower.
- 3Compare the spread, then counter. Line the offers up on rate, term, install, and SLA. The gap between high and low bid is your negotiating room.
Where the room usually is
✓ Levers worth pushing
Install waived against term, unprotected pricing where the application allows it, and a migration credit toward Ethernet with the same carrier. Ask what the equivalent Ethernet circuit costs, explicitly.
● What a padded quote looks like
Protected pricing quoted by default without asking your requirement, and a long renewal with no Ethernet or wavelength comparison offered.
OC-3 Connection pricing, straight answers
What does an OC-3 cost?
It varies by metro and by path, and it usually costs more per megabit than Ethernet at similar bandwidth. Term and protection level are the main variables.
Do I need a protected ring?
Only if a brief reroute is unacceptable. Protection roughly reflects a second path being held for you, so it should be a deliberate choice rather than a default.
Should I migrate off SONET?
Usually, where Ethernet or a wavelength reaches you. Price both and use the cheaper one to negotiate whichever you keep.
