The announced 1.6Tb/s figure is the capacity of an optical wavelength—not a 1.6Gbps home broadband plan. Openreach says the system will carry 400G and 800G client services and introduce national 800G wholesale services.
What does Openreach’s 1.6Tbps Ciena deal mean?
It is an optical-network capacity investment for wholesale connectivity: Openreach is adding Ciena Waveserver technology to OSEA, a portfolio intended for providers that need high-capacity links to specialist sites. The announcement describes dedicated 1.6Tb/s wavelengths carrying 400G and 800G client traffic. Those figures describe different layers of the network: wavelength capacity is not the same thing as a consumer broadband speed or an individual client service rate.

Openreach says the deployment makes national 800G services available for the first time and provides a route to faster services as customer requirements grow. These are company claims in the announcement, not independently measured performance results. The release says a 2RU chassis can support up to 32 × 400G services; it does not provide a comparable 32-service figure for 800G.
Who is the network for, and what could it connect?
OSEA is aimed at wholesale providers, rather than households buying broadband directly. Openreach lists use cases that need substantial capacity between network locations:

Openreach’s announcement describes Ciena as providing specialist support to deploy, proactively monitor, and maintain the OSEA optical product. It does not identify the wholesale customers, specific routes, rollout dates, contract value, or service prices.
What is WaveLogic 6?
WaveLogic 6 is Ciena’s coherent optical technology family, used to transmit high-capacity signals over fiber. Ciena’s February 2023 product announcement described two variants with different priorities:
Rank #2
- 10GBASE-SR SFP+ to LC Optical 10 Gigabit Ethernet Fiber transceiver module, 10GbE Multimode SFP+(compatible with both 62.5um and 50um LC cables; supports OM1/OM2/OM3/OM4 fiber cables), Duplex LC connector, 850nm, DDM, up to 300m.

- [What you Get] 2x 100% tested 10GBase-SR modules, 3-Year warranty and lifetime tech support.
| Variant | Ciena’s stated focus and capabilities |
|---|---|
| WaveLogic 6 Extreme (WL6e) | Performance-oriented; Ciena described support for single-carrier wavelengths up to 1.6Tb/s in metro ROADM deployments and 800Gb/s on the longest links. |
| WaveLogic 6 Nano (WL6n) | Footprint-oriented coherent pluggables for 400G–800G applications, including interoperable 800ZR data-center interconnect. |
The Openreach announcement names Waveserver and WaveLogic 6 but does not specify WL6e or WL6n. The product-family descriptions therefore provide background, not evidence that Openreach is deploying either named variant specifically.
What the announced figures do—and do not—establish
The 2026 announcement reports up to 32 × 400G services per 2RU chassis and dedicated 1.6Tb/s wavelengths carrying 400G and 800G client traffic. It also says the deployment introduces national 800G services. The release does not provide independent test results, measured throughput, or a third-party assessment of the deployment’s performance or scale.

Openreach’s company description in the announcement says it serves more than 680 service providers. That is a company-reported figure, not an independently audited market count, and it should not be read as the number of customers using this particular OSEA deployment.

Openreach Director of Products Nicolas Lemaitre said the investment is intended to strengthen the network for wholesale customers and prepare for growing connectivity needs, including those associated with AI applications and Critical National Infrastructure. This is Openreach’s stated rationale; the announcement does not quantify demand, identify customer commitments, or provide a forecast of capacity utilization.
