Coherent optics,
routed from the CLI.
No transponder shelf.
OcNOS-SP manages 400G and 800G coherent wavelengths directly from the routing CLI — no standalone transponder shelf, no separate optical management system. One platform for packets and photons.
Two layers. One CLI.
No transponder shelf.
IPoDWDM with OcNOS-SP converges IP routing and DWDM optical transport into a single control plane. Coherent transceivers — OpenZR+ or OIF 400ZR in QSFP-DD form factor — plug directly into router ports. OcNOS-SP configures modulation, FEC, laser tuning, and monitors optical performance. The transponder shelf disappears. The optical management system disappears.
IPoDWDM sits between SP routing and the data center.
Start with SP Networks for the routing foundation. IPoDWDM adds coherent optical transport between SP nodes without a separate management system.
Configure it like an Ethernet interface.
From your OcNOS CLI session: set modulation, FEC, laser frequency, monitor pre-FEC BER and OSNR. No second login. No separate optical controller.
From three layers to one.
Converged IPoDWDM simplifies fault isolation, reduces failure domains, and halves provisioning time.
Estimate Your CAPEX Savings
Drag the slider to your number of 400G optical links. Estimates: ~$30K per legacy transponder link vs ~$8K per OpenZR+ optic.
Where IPoDWDM lives in your network.

Eliminate the transponder shelf at every ring node.
Metro networks deploy a transponder shelf at every ring node — extra power, rack space, and management. With OcNOS-SP and OpenZR+ pluggable optics, each metro router becomes its own coherent transponder. A 10-node ring eliminates 10 transponder shelves, 10 element management sessions, and typically 30–40% of site power consumption.
Per-span modulation tuning
Configure each OpenZR+ port at the optimal modulation for that fiber span — DP-16QAM for short hops, DP-QPSK for longer spans — no transponder vendor constraint.
MEF 3.0 Carrier Ethernet
E-Line, E-LAN, E-Tree, and E-Access over the converged platform. ITU-T Y.1731 OAM for per-service SLA monitoring and fault isolation.
A 10-node metro ring replacing transponder shelves saves $2–5M in hardware CAPEX. Power reduction: 30–40% per site.
UfiSpace S9600-56DX (4.8T), Edgecore AS7535-28XB (4.8T) — both with QSFP-DD ports validated for OpenZR+ and OIF 400ZR.
Connect DCs at 400G or 800G — without a dedicated DCI platform.
Traditional DCI platforms cost $100K–$500K per node pair. OcNOS-SP with OIF 400ZR delivers the same connectivity from the aggregation router — the DCI link is just another port, managed from the same CLI as your DC fabric routing. For AI workloads, 800G coherent on Broadcom Tomahawk 5 provides the highest-density inter-DC bandwidth.
OIF 400ZR for DCI ≤120km
DP-16QAM at 400G, sub-1U per wavelength. Eliminates dedicated DCI chassis for most enterprise and cloud SP scenarios.
800G coherent for AI Fabric DCI
Bulk east-west traffic between GPU clusters: 800G coherent on Broadcom TH5 (AS9817-64D) without proprietary optical platforms.
Replacing a dedicated DCI platform with OcNOS-SP + ZR optics reduces per-link CAPEX by 70–80%. Typical payback under 18 months.
Carry cell site traffic optically — without a separate transport network.
Mobile backhaul aggregates hundreds of cell sites through a metro ring to the mobile core. With IPoDWDM, mobile backhaul and metro optical transport run on the same OcNOS-SP platform. The cell site router (OcNOS-SP CSR, TIP DCSG) hands off to the metro aggregation node, which carries traffic over coherent DWDM without a transponder shelf.
Timing preserved end-to-end
IEEE 1588v2 Class C/D timing from the cell site router (OcNOS-SP CSR) carries through the metro IPoDWDM segment without degradation.
SR-MPLS xHaul over converged platform
5G fronthaul, midhaul, and backhaul carried as SR-MPLS labeled paths over the same IPoDWDM metro platform.
OcNOS-SP CSR at cell site + OcNOS-SP PLUS at metro aggregation = single-vendor, single-management-plane mobile backhaul from gNB to mobile core gateway.
OpenZR+ reaches 1,800km on amplified line systems.
At DP-QPSK modulation, OpenZR+ extends to 1,800km+ on G.652 fiber with EDFA amplification. OcNOS-SP manages all coherent parameters — modulation, baud rate, FEC gain — while the DWDM line system handles amplification. Long-haul IP transport managed entirely from the routing CLI.
Adaptive modulation for reach optimization
DP-16QAM (400G, short reach) → DP-8QAM (300G, medium) → DP-QPSK (100–200G, long reach). Switch in-service for dynamic capacity management.
Alien wavelength over third-party DWDM
OpenZR+ transceivers run as alien wavelengths on third-party EDFA line systems. Line system provides amplification; OcNOS-SP owns coherent tuning and routing.
DP-16QAM: 400G, up to 120km unamplified / 500km amplified.
DP-8QAM: 300G, up to 800km amplified.
DP-QPSK: 100–200G, up to 1,800km amplified.
What OcNOS-SP manages — and which transceivers are validated.
Every optical parameter is configurable and monitorable from the standard CLI. A broad multi-vendor transceiver ecosystem gives you freedom of choice.

|---|---|---|---|---|---|
| OIF 400ZR DCI | 400G | DP-16QAM | 120km (amplified) | QSFP-DD | Short-reach Data Center Interconnect |
| OpenZR+ Metro / Long-haul | 100–400G | DP-16QAM / DP-8QAM / DP-QPSK | 1,800km (amplified) | QSFP-DD | Metro transport, long-haul, alien wavelength |
