We all know that the traditional 100G optical module uses 4x25G optical channels parallel or wavelength division multiplexing for transmission, and the mainstream optical modules on the market are mainly 100G SR4/CWDM4/PSM4/LR4/ZR4 and so on. The 100G single-wave optical module we introduce to you today uses single-wavelength 100G PAM4 modulation technology, which can better reduce production costs and obtain higher transmission efficiency.

 

I.the difference between the traditional 100G optical module and 100G single-wave optical module

 

The traditional 100G optical module uses 4x25G NRZ technology. Using four separate transmit and receive channels, four 25Gb/s electrical data can be converted into four LAN WDM optical signals, which can then be multiplexed into one 100Gb/s optical transmission. At the receiving end, the 100Gb/s optical input is demultiplexed into a 4-channel LAN WDM optical signal, which is then converted into a 4-channel electrical data output.

In addition, the traditional 100G optical module requires separate transmitting and receiving devices on each channel, which not only increases the power consumption and space occupation of the optical module, but also increases the cost. The 100G single-wave optical module converts four 25Gbps NRZ signals at the end of the circuit into a single 53Gbps signal through DSP processing of PAM chip by driving the cooled electric absorption modulated DFB laser (EML). This technology significantly increases the signal transmission rate and effectively reduces the number of signal channels required compared to traditional NRZ modulation technology.

The 100G single-wave optical module uses the more advanced PSM4 parallel transmission technology, reducing the number of light transmitting and receiving units from 4 to 1, which can reduce the cost by more than 40%. Because 100G single-wave technology uses single-channel PAM4 technology, this innovation makes it feasible to smoothly upgrade 100G to 4x100G (400G optical module).

 

II.ETU-LINK 100G single wave series products

 

ETU-LINK 100G single-wave optical module currently has four models: 100G QSFP28 DR1/FR1/LR1/ER1. They are suitable for services that use single-mode fiber for high-speed data communication of 100Gb/s, operating at 1310nm, and the optical signal is multiplexed to the single-mode fiber using a duplex LC connector. The series is designed according to QSFP28 multi-source Protocol (MSA) with form factor, optical/electrical connection and digital diagnostic interface. The 100G QSFP28 optical module has a maximum transmission link of 40km in single-mode OS2 optical fiber, and is usually used in data center interconnection, 100G Ethernet, enterprise networks and other fields.

 

As a professional platform for a full range of optical networking products and services, ETU-LINK provides you with a reliable and cost-effective, cost-saving single-wave 100G QSFP28 optical module in an airtight package (or non-airtight) solution.
