Carritech Optics CT-1.6T-DR8, OSFP PAM4 1311nm SMF Optical Transceiver Module

Carritech Optics CT-1.6T-DR8, OSFP PAM4 1311nm SMF Optical Transceiver Module is a high-speed optical transceiver designed for 1.6Tb/s networking in demanding data-center and high-performance computing environments. It provides an aggregate data rate of 1.6Tb/s using 8 × 212Gb/s PAM4 electrical lanes and 8 × 106.25GBd PAM4 optical lanes. The module is designed for applications such as AI clusters, HPC systems, data-centre interconnect, and 1.6T Ethernet.

The CT-1.6T-DR8 uses an OSFP MSA IHS close-top, hot-pluggable form factor for integration into compatible high-speed networking equipment. Its silicon-photonics transmitter uses 1310nm-class DFB lasers, while the receiver uses PIN technology. The wavelength range of 1304.5nm to 1317.5nm, with a typical wavelength of 1311nm, supports the optical transmission requirements of the module.

Designed for single-mode fibre connectivity, the optical interface provides 8 × 106.25GBd PAM4 lanes in a DR8 configuration. The module supports a maximum reach of 500m and uses a dual MPO-12/APC optical connector. This combination provides high-density optical connectivity for short-reach data-center interconnects and high-bandwidth network links.

The module supports average launch power of -3.3dBm to +4dBm per lane, OMA up to +4.2dBm per lane, extinction ratio of ≥ 3.5dB, and side-mode suppression ratio of ≥ 30dB. A supply voltage range of 3.135V to 3.465V and maximum power consumption of 23W support deployment in compatible high-speed networking platforms. The case temperature range is 0°C to 70°C.

Digital diagnostics through DOM and a two-wire interface provide monitoring capabilities for network deployment and maintenance. The CT-1.6T-DR8 complies with OSFP MSA Rev 5.0, IEEE 802.3dj D2.0, and CMIS Rev 5.2, with RoHS environmental compliance. Its high aggregate bandwidth and DR8 optical architecture make it suitable for next-generation AI infrastructure, HPC networks, data-center interconnects, and 1.6T Ethernet applications.
