400G QSFP-DD ZR4 DWDM4 Tunable 120km DDM Duplex LC Optical Transceiver Module

The QSFP-DDZR module is compliant with the OIF 400ZR standard and is amplified to provide DWDM DCI transmission range of 80-120 km via SSMF. Other types of fiber, such as hollow-core fibers, are accommodated by the module. According to CMIS, Digital Diagnostic features can be accessed via the TWI interface. To offer clients superior transmission features, the QSFP-DD400G ZR optical transceiver comes with an integrated optical engine that is coherent, with a narrow linewidth tunable laser and a 7nm-coherent DSP ASIC. This Dual Polarization 16QAM (DP-16QAM) modulation is supported by the QSFP-DD 400G module, and CFEC guarantees compatibility. Additionally, 4x100GbE could be enabled by ZR. ZR module. Compatible with QSFP-DD MSA, it includes a 76-pin connector for hot plugging. The power consumption of 19W is the reason why this optical unit works ideally to be used with Data Center Interconnections (DCI) network links

For up to 400 Gigabit Ethernet, this parallel, fiber-optic QSFPDD double-density device is plug-in-ready. With multiple lanes, this is a powerful device for exchanging and connecting data at short distances. 8 channels of electronic information at a speed of 53.125 Gbit/s could be converted into four optical signal channels at a speed of 106.25 Gbit/s each by using this module. In turn, it transforms four channels of 106.25 Gbit/s of visual inputs into eight channels of output electrical information at one end. Each lane is capable of operating for up to 60 meters using OM3 fiber, and as high as 100 metres using OM4 fiber that has FEC. These optical modules were designed to function with 850 nm multimode fibers with a wavelength of 850 nm. It is an MTP 12-fiber (MPO) connectivity. The VCSELs and circuits that have been tested that have been proven to work effectively, last for a long period of time, and provide steady service are utilized to create the CMIS standard for QSFP-DD modules. The acronym refers to CMIS, which stands for Common Management Interface, 400G SR4 module.
