Copenhagen, Denmark. – September 23,2025, Bifrost today jointly announced with Semtech Corporation (Nasdaq: SMTC), a leading provider of highperformance semi-conductor, Internet of Things (IoT) systems and cloud connectivity service solutions, the launch of Bifrost’s DSP free 25 Gbps transceiver with 40 km reach.
Our QC (quasi-coherent) technology provides a long list of distinct advantages
• Lower cost, power consumption and compact footprint (SFP 28/56 compatible)
• DSP free PIC based optical solution
• Easy upgrade from 10 Gbps to 25 Gbps in DWDM networks
• Wavelength selective receiver for filter less DWDM
• Standard EML transmitter
• Near-zero latency and longer reach due to DSP-free analog dispersion compensation
• European R&D based in Denmark with production in Belgium
Demonstration of the 25 Gbps complete transceiver with 40 km reach will take place at the Bifrost booth at the ECOC exhibition in Copenhagen from September 29 to October 1 (Danish Pavilion stand D3 Hall E).
The 25 Gbps solution utilizes Bifrost’s 25 Gbps DSP free Transceiver PIC. “In combination with Semtech’s GN2146 CDR Bifrost’s Quasi-Coherent Receiver enables 40 km reach at 25 Gbps in the C-band,” said Jesper Bevensee Jensen, CTO at Bifrost Communication.
Jesper continues: “Soon to follow is the 50 Gbps solution which utilizes Bifrost’s 50 Gbps PAM4 Silicon Photonics Transceiver PIC in combination with Semtech’s Tri-Edge™ CDR IC. The 50 Gbps enables 20 km reach in the C-band targeting requirements for 6G fronthaul set by MOPA.” (The Mobile Optical Pluggables Alliance)
"The industry requires flexible solutions that can address varying distance requirements without compromising performance or increasing complexity," said Raza Khan, Director of Marketing, Wireless at Semtech's Signal Integrity Products Group. "Semtech’s comprehensive portfolio spanning 10 Gbps to 50 Gbps with our ClearEdge®, Tri-Edge™, and FiberEdge® product lines provides system vendors and carriers with the tools they need to solve the hardest problems in 5G and 5G-Advanced fronthaul deployments, whether they're dealing with 10 km metropolitan links or challenging 40 km+ rural deployments. The GN2146C exemplifies our commitment to enabling all architectures with best-in-class CDR and TIA technology."
Bifrost’s product roadmap and production of transceivers
Bifrost continues to push the boundaries of their proprietary Quasi Coherent transceiver technology, and the product roadmap contains plans for DSP free 25 Gbps 80 km, 50 Gbps 40 km and 100 Gbps 20 km.
Bifrost Communications is also announcing their partnership with the newly established ESTEL Optical Transceiver Production Company in Belgium. The ESTEL European facility is currently the only fully European Transceiver production line producing high-quality optical transceivers.
