About QIANWU
A Shenzhen-based optical interconnect project partner
QIANWU supports AI data-center and high-performance network buyers with 400G, 800G and 1.6T optics, AOC/DAC and model-specific sourcing coordination. We connect real PN/BOM and host requirements with technical review, supplier-backed quotations and delivery follow-up—not unverified compatibility promises.
QIANWU Optical Portfolio
400G, 800G & 1.6T — find the right link
Start from the physical link requirements, not an unverified compatibility claim. Exact supplier PN, transceiver form factor and availability are reviewed for each deployment.

Understand the full link before selecting the interconnect
High-speed optics work inside a system. Server, NIC / DPU, switch port, protocol, topology, connector, fiber and reach must be reviewed together.

Typical Project Scenarios
Start from the business problem, not a generic catalog
These are common requirement patterns QIANWU can structure into a technical and commercial RFQ.
AI Cluster Expansion
Existing switch or NIC platform needs additional 400G / 800G / 1.6T interconnect capacity.
Best input: platform + port + quantity + required date.
Urgent Optical Replacement
An active project faces lead-time pressure, shortage risk or an approved replacement requirement.
Best input: original PN + quantity + delivery deadline.
New Data Center BOM
The exact optic is not fixed yet and must be selected from the server, NIC / DPU, switch and topology.
Best input: BOM + topology + reach + connector / fiber.
InfiniBand NDR Project
Switch-to-adapter connectivity needs platform-specific validation for form factor, media and topology.
Best input: switch + HCA / DPU + length + port mode.
Project Workflow
From RFQ to delivery
Requirement review, product matching, sample validation, supply confirmation and delivery follow-up.
01 / RFQ
Requirement Review
PN/BOM, platform, rate, reach, quantity and target delivery.
02 / SELECTION
Product Matching
Confirm form factor, optical type, connector and media.
03 / VALIDATION
Sample & Validation
Coordinate samples and technical validation when required.
04 / SUPPLY
Supply Confirmation
Confirm availability, quantity and lead time for the exact requirement.
05 / DELIVERY
Delivery Follow-Up
Coordinate shipment and project follow-up.
Evidence Before Commitment
Professional means confirming what can actually be confirmed
QIANWU separates technical facts, compatibility assumptions and commercial commitments so the customer can make a clearer decision.
QA & validation workflow
Validation is coordinated against the actual project. Third-party technical or supply resources are not presented as QIANWU-owned facilities.

Technical Center
Technical content built around real selection decisions
Use the Technical Center to understand form factors, optical architectures, cabling and the information required before an RFQ.
From OSFP vs QSFP-DD to DR8 vs FR4
QIANWU technical content focuses on the decisions that change product selection: host port, protocol, reach, fiber, connector, breakout and platform context.
