Among the features that made the 6500 attractive were its use of coherent detection and its Optical Transport Network (OTN) switching capability, XO CTO Randy Nicklas said in a statement.
Why this matters
XO has some ambitious ideas for its network, including 100Gbit/s managed wavelength services. It could provide good bragging rights for Ciena, the early leader in 100Gbit/s gear.
In August, XO picked Nokia Networks for the core of its 100Gbit/s network and it's now gone to Ciena, which it's been using for metro Ethernet.
The primary vendor left out of that 100Gbit/s equation so far is Infinera Corp. (Nasdaq: INFN), which along with NSN had been XO's long-haul transport provider. This doesn't necessarily mean Infinera is being shut out. XO wanted to move quickly with this phase of deployment, and the Infinera DTN-X might not have been available at the moment.
XO is taking a more measured approach to the next phase, having issued a request for proposals (RFP) for speeds beyond 100 Gbit/s, Nicklas told Light Reading in August.
