400G CFP2 BiDi Digital Coherent Optical Module: BIDI-400G-CFP2-DCO
400G CFP2 BiDi Digital Coherent Optical Module Overview
The BIDI-400G-CFP2-DCO is a CFP2 pluggable digital coherent optical module with software-configurable line-side capacity across 100G, 200G, and 400G. The line side presents two dedicated LC/UPC ports, one transmit and one receive, each operating on a full C-band tunable coherent signal (Ch.13-61, 6.25 GHz flex grid). Coherent modulation from QPSK up to 16-QAM lets the operating point trade capacity for reach, with amplified DWDM links reaching up to 480 km and unamplified point-to-point links reaching approximately 40 km.

400G CFP2 BiDi Digital Coherent Optical Module Description
The BIDI-400G-CFP2-DCO is a CFP2-pluggable digital coherent optical module for metro, long-haul, and data center interconnect networks. Line-side capacity is software-configurable across 100G, 200G, and 400G, letting operators tune capacity and reach per link without swapping hardware.
The line side presents two dedicated LC/UPC connectors, one transmit port and one receive port, each carrying a full C-band tunable coherent signal across channels 13 to 61 on a 6.25 GHz flex grid. This is a standard duplex design, not a single-strand shared-wavelength BiDi interface.
The module uses digital coherent optics with an integrated DSP, supporting PM-QPSK and PM-16QAM modulation. 16-QAM favors capacity at shorter reach; QPSK favors longer reach at lower capacity. On the client side, the module maps 100GbE, 200GbE, and 400GbE Ethernet signals as well as OTU4 and OTUC1 OTN framing onto the coherent line side.
Amplified DWDM configurations support reach up to 480 km, while unamplified point-to-point links support approximately 40 km, depending on the configured line rate and modulation format.
The CFP2 form factor follows the CFP MSA CFP2 Hardware Specification. The digital coherent design follows the OIF-CFP2-DCO-01.0 Implementation Agreement from October 2018, defining the mechanical envelope and host electrical interface shared across CFP2 digital coherent modules.
Typical deployments include metro DWDM networks, long-haul backbone links, and data center interconnect (DCI) routes, where tunable full C-band coverage and configurable 100G, 200G, and 400G line rates let one module serve multiple points in the network.
The module operates from a single +3.3V power supply with a maximum power consumption of 26 W, across an extended -5°C to 80°C temperature range. DDM/DOM digital diagnostics monitoring is supported for real time visibility into optical parameters. The module is RoHS and CE compliant.
Frequently Asked Questions
Does the BIDI-400G-CFP2-DCO use a single fiber for bidirectional transmission?
No. The module presents two dedicated LC/UPC connectors on the line side, one transmit port and one receive port, with a standard duplex fiber count. It is not a single-strand, shared-wavelength BiDi design. Confirm the duplex LC/UPC connector layout against the fiber plant before provisioning the link.
What is the difference between the BIDI-400G-CFP2-DCO and the 400G-CFP2-DCO?
Both are EdgeOptic CFP2 digital coherent optical modules, but they target different reach and power envelopes. The BIDI-400G-CFP2-DCO configures line-side capacity across 100G, 200G, and 400G, reaches up to 480 km in amplified DWDM configurations, and draws a maximum of 26 W across a -5°C to 80°C temperature range. The 400G-CFP2-DCO is EdgeOptic's dedicated dual-rate module, reaching up to 640 km at 400G and 2000 km at 200G in amplified configurations, with a maximum power draw of 36 W across a 0°C to 75°C range. Match the module to the rate flexibility, reach, and power budget the deployment needs before ordering.
