Explore our premier selection of advanced optical modules, media interfaces, and custom connector cages engineered for modern hyper-scale networks.
Analysing the structural shifts, market demands, and global supply patterns governing high-performance optical networking.
The rise of generative AI clusters, large language models (LLMs), and hyper-scale cloud fabrics has triggered an unprecedented demand for data throughput. Optical transceivers, particularly 400G QSFP-DD and 800G OSFP form factors, are essential in resolving I/O bottlenecks within data centers worldwide.
Telecom operators are transitionally deploying 5G Standalone (SA) architectures. This rollout demands industrial-grade Bidi SFP, SFP28 (25G), and DWDM SFP+ optical interfaces capable of handling wide thermal ranges (-40°C to 85°C) at edge nodes, ensuring network resilience under varied ambient conditions.
China continues to be the bedrock of optical transceiver manufacturing. Through comprehensive vertical integration, from III-V semiconductor epitaxy and optoelectronic chip packaging (TO-can, COB) to testing Automation, Chinese suppliers like Xelivor offer unmatched cost efficiency and supply chain security.
Xelivor Optoelectronics Co., Ltd. is a dedicated manufacturer of optical transceivers and high-density fiber connectivity solutions. Established in 2016, our operations serve the telecommunications, global data center, enterprise campus, and cloud computing sectors. Headquartered in China, we manage a specialized manufacturing facility spanning 386 m² designed to support rapid iteration and low-latency production workflows.
Over our 8-year operational history and 6 years of international export experience, Xelivor has generated annual export revenues exceeding USD 12 million. Our commercial footprint extends across North America, Europe, Southeast Asia, the Middle East, and South America, delivering robust compatibility and verified performance directly to global network architects and system integrators.
We specialize in the end-to-end design, development, and mass production of optical modules, covering legacy 1.25G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, up to 400G QSFP-DD and early-phase 800G OSFP architectures. Our R&D division consists of 68 engineers specializing in optoelectronics, high-speed PCB layouts, thermal engineering, and firmware programming. Over the past year alone, this team successfully launched more than 85 new products to keep pace with changing network requirements.
Product reliability is maintained through a rigorous multi-stage quality assurance system. Our quality workflow incorporates incoming material inspection (IQC), in-process quality control (IPQC), thermal aging chambers, digital diagnostic monitoring (DDM) verification, insertion loss testing, and live-switch compatibility verification. Our dedicated team of 32 QA inspectors verifies that each module complies with international standards, including CE, FCC, RoHS, and MSA guidelines.
Xelivor coordinates with more than 850 verified supply chain partners, ensuring material availability and stable lead times. We support global procurement through comprehensive OEM, ODM, custom firmware coding, private-label branding, and bespoke packaging configurations. Our goal remains delivering cost-effective, high-quality, and future-ready optoelectronic solutions for global network infrastructures.
Understanding the evolution of optical transceiver technology from standard pluggable modules to advanced integrated optoelectronics.
As power consumption becomes a critical design challenge at 800G and 1.6T, LPO is emerging as a vital architecture. By removing the DSP (Digital Signal Processor) from the pluggable module and relying on linear analog components, LPO dramatically reduces power dissipation and latency, making it ideal for latency-sensitive AI clusters.
Silicon Photonics integrates laser sources with silicon-based optical circuits, replacing traditional discrete optical components. This enables automated, wafer-scale testing and packaging, drastically lowering manufacturing costs while improving chip-to-chip interconnect density at 400G and above.
Historically limited to long-haul transoceanic links, coherent optics (using DP-QPSK and DP-16QAM modulation formats) are migrating into the metro and data center interconnect (DCI) spaces through 400ZR and 800ZR form factors, supporting single-wavelength transmission over distances exceeding 120km.
| Form Factor | Data Rate Range | Typical Reach | Laser Type / Optical Engine | Primary Target Application |
|---|---|---|---|---|
| SFP / SFP+ | 1.25G to 10G | 100m to 80km | VCSEL / DFB (Directly Modulated) | Enterprise LAN, Campus Backbone, FTTH Edge |
| SFP28 | 25G / 32G FC | 100m to 40km | DFB / EML (Electro-absorption Modulated) | 5G Fronthaul, 25G Ethernet Switch Ports |
| QSFP28 | 100G | 100m to 80km | 4x 25G CWDM4 / LAN-WDM EML | Data Center Interconnects, Enterprise Core Routing |
| QSFP-DD | 400G / 800G | 100m to 10km+ | 8x PAM4 VCSEL / Silicon Photonics Coherent | AI/ML Clusters, Hyper-scale Cloud Core Spine-Leaf |
How Xelivor’s product portfolio resolves networking bottlenecks across various infrastructure topologies.
AI clusters training LLMs require ultra-low latency and zero packet loss. Deploying 400G QSFP-DD SR8 modules with MTP/MPO-16 interface connections ensures optimal throughput. Supported by digital diagnostics (DDM), network operators can proactively monitor transceiver operating temperatures, bias currents, and optical power to avoid link failures.
Outdoor remote radio heads (RRH) require rugged, temperature-hardened optical transceivers. Our 25G SFP28 40km SMF modules are built with industrial-grade components, providing reliable backhaul links under extreme weather variations (-40°C to 85°C) without requiring active cooling.
Corporate LAN upgrades require compatibility with legacy multi-vendor switch environments (e.g., Cisco, Juniper, Arista). Our Cisco SFP-10G-LR compatible modules are pre-programmed with vendor-specific EEPROM code, ensuring seamless plug-and-play installation without error alerts.
A inside look at Xelivor's manufacturing, aging, and QA labs where reliability is validated daily.
Our production facilities are equipped with automated die bonders, optical spectrum analyzers (OSAs), high-speed oscilloscopes, and error-rate testers (BERT). These instruments confirm that every optical module leaving Xelivor's assembly line meets strict limits for jitter, optical return loss (ORL), and wave shape.
