Efficient Enabling: 100G O Band DWDM 10km Optical Transceiver

  • May 19. 2025

In the wave of digital transformation, the demand for high-speed, large-capacity optical transmission in data centers, 5G bearer networks, and metropolitan area networks continues to rise. For medium- and short-distance high-density networking scenarios, the 100G QSFP28 O-Band DWDM 10km optical module launched by ETU-LINK has become a "weapon" for building efficient optical communication networks with its unique technical advantages. This article will provide you with an in-depth analysis of the core value and application scenarios of this product.


一、Product Overview


The 100G O Band DWDM 10km Optical Module is based on dense wavelength division multiplexing (DWDM) technology and is designed for medium and short-distance high-speed transmission scenarios within 10 kilometers.



Its core features include:
1. PAM4 modulation with KP4 FEC function, the rate can reach 106.25Gb/s
2. Wavelength: 1295.56~1312.58nm (O25~O55)
3. Device solution: DWDM EML transmission and PIN reception

4. Commercial-grade power consumption: <3.5W



二、Why Choose O-Band DWDM Solution?



1. Low dispersion loss, more stable transmission
O Band is located in the low dispersion window of optical fiber. Combined with DWDM narrow wavelength spacing technology, it can effectively reduce the influence of dispersion, ensure high integrity of signals within 10km, and reduce the need for relays.


2. Strong compatibility:

Compatible with mainstream switch and router brands, plug and play, simplifying the deployment process.



三、Typical Application Scenarios



1. Data Center Interconnect (DCI)
Enables 100G high-speed interconnection between data centers in the same city, meeting high-bandwidth requirements such as virtual machine migration and data backup, and building a low-latency, highly reliable DCI network.


2. Enterprise park/smart city networking
Suitable for park backbone networks in government, finance, education and other industries. It carries services such as 4K video conferencing and IoT terminal access, creating an intelligent information highway.


3. Telecom network expansion and 5G fronthaul
Help operators upgrade the metropolitan access layer network at low cost, and provide high-density transmission solutions for 5G base station fronthaul and home broadband gigabit access.



In an era of explosive growth in traffic, efficient and reliable connections are the core cornerstone of digital transformation. Driven by technological innovation, ETU-LINK 100G O Band DWDM 10km optical module continues to create a "faster, more agile, and smarter" optical transmission foundation for thousands of industries.
