Bifrost Communications Announces the First Customer Deliveries of 25 Gbps / 40 km Transceivers and Launches its Priority Access Program at OFC 2026 

Copenhagen, Denmark – March 2026: Bifrost Communications today announces a major milestone in its evolution as a provider of complete transceiver solutions: the first customer deliveries of its 25 Gbps transceiver with 40 km reach is scheduled for Spring 2026. 

The announcement marks a significant step forward for the company and reinforces its commitment to delivering high-performance, cost-efficient optical solutions for next-generation DWDM networks. 

Bifrost Communications will showcase its technology at OFC 2026 in Los Angeles, where customers and partners are invited to experience the company’s innovative quasi-coherent (QC) technology and discuss deployment opportunities. 

Join the Priority Access Program 

To support customers preparing for network upgrades and expansion, Bifrost is launching its Priority Access Program. Participants will: 

• Receive early test samples 

• Gain priority for volume orders 

• Secure supply as production capacity ramps up 

This program is designed to give network operators and system integrators a strategic advantage as demand for high-capacity, cost-optimized solutions accelerates. 

Bifrost’s proprietary QC technology delivers distinct competitive advantages 

• Lower cost, reduced power consumption, and compact footprint (SFP28/SFP56 form factors) 

• DSP-free PIC-based optical architecture supporting both 25 Gbps and 50 Gbps transceivers 

• Seamless upgrade from 10 Gbps to 25 Gbps in DWDM networks 

• Wavelength-selective receiver enabling filterless DWDM 

• Standard EML transmitter 

• Near-zero latency and extended reach enabled by DSP-free analog dispersion compensation 

By eliminating the need for digital signal processing (DSP), Bifrost achieves lower latency, reduced power consumption and a simplified architecture improving at the same time dispersion reach and power budget. 

Future development & Production in Europe 

Bifrost keeps working to advance its proprietary Quasi Coherent transceiver technology with plans to expand its DSP-free portfolio. The current offer includes 10, 25 and 50 Gbps. 100 Gbps is in development and Bifrost continues to work on increasing reach for all transceivers in the range. 

This evolution will bring the benefits of Bifrost’s Quasi Coherent architecture to higher bit rates, empowering network operators to efficiently manage accelerating traffic growth and the sustained demand for increased bandwidth. 

With R&D based in Denmark and production in Belgium, Bifrost combines European photonics innovation with scalable manufacturing capability to support increasing global demand.

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 on 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.

• Facilitates upgrade of existing networks from 10 Gbps to 25 Gbps (C-band / DWDM)
• Meets the MOPA requirements for 6G mobile networks with 50 Gbps

A live demonstration of the 25 Gbps complete transceiver with 40 km reach will take place at the Bifrost booth 4952 and on the Semtech booth 1028. 

The 25 Gbps solution provides an easy upgrade of existing Access networks from 10 Gbps to 25 Gbps. The 50 Gbps enables 20 km reach at 50 Gbps in the C-band targeting requirements for 6G fronthaul set by MOPA (The Mobile Optical Pluggables Alliance) 

The 50 Gbps solution utilizes Bifrost’s 50 Gbps PAM4 Silicon Photonics Transceiver PIC. “Together with Semtech’s Tri-Edge™ CDR IC, Bifrost’s Quasi-Coherent Receiver enables 20 km reach at 50 Gbps in the C-band,” said Jesper Bevensee Jensen, CTO at Bifrost Communication. These innovative solutions are based on Bifrost’s proprietary Quasi Coherent transceiver technology.
