Bifrost Communications is offering complete Quasi-Coherent Transceivers
Bifrost Communications has launched its first 25 Gbps complete DSP free low latency Quasi-Coherent Transceiver with 40 km reach, and we are currently taking orders for samples for testing. Samples ordered will be delivered during Q2 / Q3 2026. We encourage you to sign up for our Priority Access Program, which grants you access to early samples and priority on volume orders as we ramp up production over the next 12 – 24 months.
Quasi-Coherent Receiver Optical Sub-Assembly (QC-ROSA)
We can also deliver the QC Optical Sub-Assembly as a component. This would enable you to integrate the QC technology into your own Transceivers.
The QC-ROSA for a 25 Gbps receiver with up to 40 km C-band reach
- Compatible with standard EML and DML transmitters
- Fits into SFP28 housing (ROSA dimensions (W, H, L: 5mm. 5 mm, 14 mm)
- Is a DSP free receiver
- Has -24 dBm sensitivity at 20 km SSMF (-16 dBm at 40 km)
The Licensing Option
You can also license the QC-technology. In this option we provide you with a reference design for a QC-ROSA so that your engineers can make the final design which fits your particular requirements. Part of the agreement will be a supply agreement for the QC-ASIC which we mass produce
