Coherent Transceivers

Improve bandwidth on short and long distance DWDM networks with tunable coherent transceivers

Transmitting terabits of data up to 3000 kilometers, coherent optical transceivers have been used in long-haul telecommunications and are now becoming standard for shorter-distance high-bandwidth connections in metro networks and between data centers.

Coherent transceivers have tunable lasers to achieve different optical wavelengths offering a flexible solution to ensure that your full DWDM capacity is used. Coherent optical transceivers were originally proprietary in design, but now adhere to MSA standards, such as CFP2-DCO and 400G ZR/ZR+.

With the move to more and more resource-hungry applications such as AI and machine learning, virtual and augmented reality, data centers need to handle much greater amounts of traffic.

Pluggable coherent optical transceivers are now available for higher bandwidths up to 400G, covering distances of between 120km to 480km, with the development of 800G coherent transceivers on the horizon.

Coherent Optical Transceivers – for short and long-haul applications

Coherent optics were developed to meet the challenge of increasing volumes of data traffic and the limit to the number of wavelengths that can be used in DWDM transmission. Using a higher modulation technique known as “polarization multiplexing”, coherent transceivers are able to transmit more data on a single wavelength over a single fiber for greater distances.

Coherent optical transceivers are used in a wide range of applications from data center links, metro networks through to long-haul and undersea links. Originally proprietary in design, coherent transceivers now adhere to MSA standards, such as CFP2-DCO and the latest QSFP56-DD 400G ZR/ZR+.
