Xelivor
High-reliability optical transceivers and high-speed cages optimized for Seoul-based telecommunication backbones and Edge-Data configurations.
The convergence of South Korea's high-density fiber networks (K-Network 2030) and advanced manufacturing hubs located in Seoul.
Information Gain Insight: As global network infrastructures shift rapidly towards 400G and 800G optical pipelines, Seoul is emerging as a critical nexus for research, component validation, and strategic manufacturing. Positioned close to elite research labs, IT centers in Pangyo Techno Valley, and the Gasan Digital Complex, local manufacturer clusters deliver precision assembly that complies with strict K-Network and international telecom criteria.
Seoul’s metropolitan region represents one of the world's most densely packed digital grids. Known globally for pioneering nationwide commercial 5G deployments and leading early experimental work on 6G physical layers, the city provides a highly specialized ecosystem for optoelectronics. Our facility leverages this unique proximity to regional IC fabs, precision optics testing institutes, and high-frequency labs. This ensures that every transceiver batch we produce is optimized for low thermal dissipation, high electromagnetic compatibility (EMC), and minimal signal degradation.
For international buyers and enterprise network architects, source-level manufacturing in Seoul represents a secure alternative to volatile trade corridors. Proximity to Incheon International Airport (ICN) guarantees seamless air cargo routing, while compliance with strict Korean environmental, safety, and manufacturing protocols (including KC Certification and eco-design standards) ensures structural product integrity from the component level up.
Why technical lead times and component architecture define our manufacturing output in Seoul.
All transceivers strictly comply with SFF, SFP28, QSFP28, and QSFP-DD MSA guidelines. Built-in EEPROM firmware is programmed to match major network equipment suppliers including Cisco, Juniper, Arista, and HP.
We test every module on live enterprise switches and OTDR test beds. Utilizing advanced Bit Error Rate Testing (BERT) and eye-diagram validation, we guarantee error-free performance under variable thermal stress levels.
Our SFP and RJ45 connector cages are constructed with premium alloys and advanced spring fingers. This provides robust electromagnetic interference (EMI) containment, critical for high-density network cards.
Robust hardware components developed to support optical engine integration and physical layer stability.

How Xelivor prepares customer environments for the transition to 400G, 800G, and Co-Packaged Optics (CPO).
In high-bandwidth applications, thermal management and power consumption are the primary bottlenecks. Current industry architectures rely heavily on pluggable form factors. However, as link demands transition from 100G/200G to 400G/800G (specifically utilizing PAM4 signaling formats), the loss margins budget becomes extremely tight. Xelivor's engineering team is developing solutions utilizing low-power DSP configurations and Silicon Photonics (SiPh) platforms to decrease power consumption below 12W for 800G modules.
| Parameter | 10G SFP+ | 25G SFP28 | 100G QSFP28 | 400G QSFP-DD |
|---|---|---|---|---|
| Modulation Type | NRZ | NRZ | NRZ / PAM4 | PAM4 (50G/100G per Lane) |
| Power Consumption | < 1.0W | < 1.5W | < 3.5W | < 10W - 12W |
| Max Link Distance | Up to 80km (ZR) | Up to 40km (ER) | Up to 80km (ZR4) | Up to 10km (FR4/LR4) / DCI Edge |
| Primary Application | Enterprise Core / Metro Access | 5G Front-Haul / ToR Switches | DCI Core / Hyperscale Spine | AI Cloud Fabrics / Next-Gen Spine |
Furthermore, standardizing electromagnetic isolation techniques is a key area of development. High-speed signals passing through switches and cages encounter severe return loss. By optimizing the contact layout and implementing custom EMI gasket materials on our SFP+ cages and RJ45 connectors, we consistently reduce electromagnetic emissions by 3dB compared to typical generic components. This enhancement reduces packet drop rates in environments with high EMI profiles.
