As network traffic keeps climbing — driven by 5G densification, cloud interconnect, and ever-larger data flows — the hardware sitting at your aggregation layer needs to keep pace without becoming the bottleneck. The Ciena 8110/8114 (2)400G QSFP-DD Module, part number 170-0339-900, is designed to do exactly that: a dense, dual-port 400G line card that slots directly into Ciena’s 8110 Coherent Aggregation Router and 8114 converged access platform.

This isn’t a consumer-facing product — it’s enterprise and carrier-grade infrastructure built for operators who need to scale 100GbE-to-400GbE aggregation cleanly, without forklift upgrades every time traffic grows. Below, we break down the specs, show how it fits into the broader 8110/8114 platform, and outline how to get pricing for your deployment.

Why This Module Matters

The 8110 Coherent Aggregation Router is purpose-built for 100GbE services and aggregation, offering dense 100GbE-to-400GbE aggregation with support for 1/10/25GbE and Ciena’s WaveLogic 5 Nano coherent optics. The 8114, meanwhile, is a rugged 2.4 Tb/s platform designed specifically for 5G, Ethernet, TDM, eCPRI, and XGS-PON in converged access networks — making it a strong fit for mobile backhaul and fronthaul builds as much as fixed-line aggregation.

The 170-0339-900 module adds two 400G QSFP-DD ports to either platform, letting operators extend high-capacity uplinks or coherent routing connections without needing a separate chassis. It’s the kind of incremental, modular scaling that keeps both CapEx and operational disruption in check.

Scaling Without the Rip-and-Replace

Here’s a friendly look at why modular line cards like this one matter for long-term network planning — they let you grow capacity in stages instead of committing to oversized hardware upfront or, worse, hitting a wall and needing a full chassis swap.

Popular Use Cases

Built for Where Networks Are Headed

Enterprise and carrier networks don’t grow in a straight line — traffic spikes regionally, new sites come online, and 5G densification keeps adding aggregation points that didn’t exist a year ago. Hardware that can only scale by swapping the entire chassis turns every growth spurt into a capital project. Modular line cards like the 170-0339-900 flip that equation: add capacity where and when you need it, without disrupting what’s already running.

That flexibility is especially valuable in the 8114’s core use case — converged access networks supporting 5G, eCPRI, and XGS-PON simultaneously. Being able to add dense 400G aggregation ports to an already-hardened, field-deployed chassis means operators can respond to real traffic growth instead of over-provisioning speculative capacity years in advance.

Support for WaveLogic 5 Nano and high-power ZR/ZR+ optics also future-proofs the investment. As coherent routing becomes standard practice for metro and long-haul aggregation, having a platform that already speaks that language means today’s line card purchase doesn’t become tomorrow’s bottleneck.

For network architects planning multi-year capacity roadmaps, that’s the real value proposition here: not just raw port density, but a growth path that doesn’t force a rebuild every time demand shifts.
