Smartoptics Dual DCP-802 Transponder for Scalable 800G Networking

Smartoptics AS announced the launch of the DCP-802 transponder.

The dual 400G/800G transponder is designed to maximize the potential of 800ZR technology for flexible and cost-efficient network scaling.

The DCP-802 transponder enables 800G networking in a compact form factor, significantly reducing power consumption and latency. It supports 1:1 transponder mode for direct conversion to DWDM. With support for 800G breakout, a single connection can be split into 2x400G links (2×400G) or 8x100G links to maximize fiber utilization. This optimizes cost per bit for communication service providers, enterprises and internet exchanges.

DCP-802 is designed for 3 use cases:

• 1:1 transponder mode: Convert 800G, 400G or 100G gray signals to coherent DWDM.
• Get more out of switches and routers with 800G breakout: Extend the life of 100G/400G ports with increased capacity or break out 800G ports into multiple lower-rate links for broader compatibility.
• Enable signal hand-off with performance monitoring: Use the transponder’s demarcation point to measure performance before handing off the signal to another system.

The dual 400G/800G transponder features 2 client ports supporting a flexible range of QSFP-DD transceiver types. On the line side, it supports coherent DWDM 400G and 800G modulation formats, with optional Layer 1 encryption for easily securing data in transit.

To optimize capacity and reach for specific network needs, the transponder supports programmable line rates from 100G to 800G in small increments. These flexible data rates are made possible with cutting-edge technologies such as dynamically adjusting modulation and constellation shaping.

“The DCP-802 transponder is a key addition to our 800G portfolio along with our 800G-capable open line systems, ROADMs, and transceivers. One of the biggest drivers for 800G is maximizing cost efficiency with breakout, and our first 800G transponder is purpose-built for this need. True to our smart design principles, it enhances cost efficiency and simplifies network architectures with its compact form factor and flexible support for pluggable optics. We look forward to helping customers make the most of 800G with the DCP-802,” says Kent Lidström, CTO, Smartoptics.

The DCP-802 is planned to be available for the 1st deliveries to the market in Q3 2025.
