Singapore, March 6, 2024– Long-distance data transmission operates through two distinct modes: coherent and non-coherent. Today, FIBERSTAMP officially unveils two trailblazing 100G QSFP28 PSM DWDM4 for Non-Coherent long-distance Subsystem. These modules, built upon a 4x25G NRZ quad-carrier DWDM solution, offer options in C-band spectra, effectively spanning distances exceeding 80km. They aim to provide more cost-effective DWDM transmission solutions for Data Center Interconnects (DCI) and Metro Area Networks. Compared to traditional coherent solutions, this approach offers advantages such as lower pricing, lower power consumption, lower latency and easier deployment.

Color ZR+ C-BAND 100G QSFP28 PSM DWDM4
- 4x 26Gbps NRZ per channel C-band 100GHz DWDM EML transmitter 48 wavelengths and PIN photo detector array receiver
- Internal CDR circuits on both receiver and transmitter channels, support CDR bypass
- Low power consumption<5W
- Up to 80km reach for G.652 SMF with external Mux/ Demux, EDFA ,CD compensation
- Up to 10km reach for G.652 SMF without external CD compensation
- Single male MPO-12(APC 8-degree) connector receptacle
It achieves a total bandwidth of 1200G under dual-fiber transmission conditions and 400G under single-fiber conditions. It seamlessly connects to 100G QSFP28 switch ports, eliminating the need for traditional DWDM optical layer equipment.
