July 17, 2024. Shenzhen, China. – In response to client application requirements, GIGALIGHT now launches the new Color X Series 100G QSFP28 DWDM1 O-BAND silicon optical transceivers. Previously, GIGALIGHT launched the Color ZR+ 100G QSFP28 PSM DWDM4 optical transceivers based on 4x25G NRZ four-carrier DWDM solution, which have been widely used in the client sides and has been highly recognized by customers.

Now launching the new Color X Series 100G QSFP28 DWDM1 O-BAND silicon optical transceivers based on 150Ghz O-BAND DWDM Grid, single-wave 100G PAM4 silicon optical modulation technology platform. Duplex LC interface is adopted to provide 16 wavelengths for selection, achieve 1600G total bandwidth on SMF dual-fiber, meet DCI interconnection applications, and can achieve 30km transmission under the support of SOA optical amplifier (10km transmission without SOA), without the need for dispersion compensation DCM module, the power consumption of this optical transceiver is less than 3.5W. Compared with coherent DWDM, this scheme has the advantages of low cost, low delay, low power consumption and easy deployment.

Color X 100G QSFP28 DWDM1 O-BAND silicon optical transceivers integrates the latest technology DSP chip to realize 4x25G NRZ to 100G PAM4 and monolithic integrated silicon optical MZ modulation chip, CWL laser achieves 150Ghz O-BAND DWDM wavelength optional.

The product has the advantages of low power consumption and high performance, and the key parameters are as follows:

• TDECQ per channel is less than 2.4dB, which is better than the protocol specification <3.4dB;
• Rx Sens(OMA) sensitivity is better than -9dBm@2.4e-4 Pre-FEC 53GBd PAM4, better than the protocol specification <-6.1dBm;
• The maximum power consumption of the optical transceiver is less than 3.5W.

GIGALIGHT focuses on integrating silicon photonics technology with traditional technology advantages to create non-coherent DWDM transmission solutions for 100G DCI networks. The core of this strategy focuses on achieving low-cost, cost-effective deployment, while relying on its innovative technical solutions to ensure that it is unique in the market and leads the industry development.
