Citynet, a facilities-based network services provider serving 17 states and Washington, D.C., has deployed Infinera’s DTN platform on a significant portion of its network. Citynet is a wholesale IXC carrier with an 8,000 route mile network footprint.
Infinera’s “Digital Optical Networking” technology provides the advanced DWDM and digital bandwidth management capabilities and will support the increased demand Citynet is seeing for optical wavelength (2.5 — 10 Gbps), private line (DS3 — OC192 and Ethernet), and IP-based service offerings. The DTN supports 800 Gbps of DWDM capacity and delivers a variety of manageable and protectable SONET/SDH and Ethernet-based services, including 10 Gigabit Ethernet LAN PHY.
The announcement represents the third customer in as many months.

- Earlier this year, Infinera announced deployments by Level 3 Communications and OnFiber Communications.
- Infinera is offering an optical transport platform based on its Photonic Integrated Circuits. The Infinera DTN supports 400 Gbps, i.e., forty 10 Gbps channels in a half rack, and 800Gbps (eighty 10 Gbps channels) in a full rack.. 100 Gbps line cards support a variety of hot-swappable client interfaces including OC-192/STM-64, OC-48/STM-16, 10 Gigabit Ethernet LAN PHY and WAN PHY, and Gigabit Ethernet. The platform runs Infinera’s IQ Network Operating System to automate network discovery, configuration, and provisioning via GMPLS.
- Unlike conventional optical systems, which use analog optical devices for key networking functions, the Infinera DTN uses digital technology. Its photonic integrated circuits convert all traffic from optical to electronic signals, allowing the DTN to add and drop, multiplex, groom, and protect circuits digitally rather than optically. Infinera’s Photonic Integrated Circuits include a 100 Gbps transmitter, which integrates ten lasers, ten 10 Gbps modulators, and an optical multiplexer; as well as a 100 Gbps receiver, which integrates an optical demultiplexer and ten photodiodes. Each enables low-cost optical-electrical conversion on a semiconductor chip.
