Import 100g Qsfp28 Passive Copper Cable — Buy in wholesale FOB from Supplier in Taiwan

The Optech Technology 100G QSFP28 Passive Copper Cable is a direct-attach copper (DAC) assembly built for short-reach, high-bandwidth connections within data centre racks and between adjacent cabinets. It provides four independent full-duplex channels, each supporting data rates up to 25.78125 Gbps, for a combined throughput of 100 Gbps. The cable is fully compliant with SFF-8665 and SFF-8679 for the QSFP28 interface, and meets IEEE 802.3bj electrical specifications for 100GBASE-CR4 operation.

As a passive assembly, this cable contains no active signal conditioning components, relying instead on quality copper conductors to carry the differential pairs directly between host ports. This design results in very low insertion loss and a bit error rate (BER) better than 10⁻¹⁵, while eliminating the need for additional power at the cable itself. The maximum reach is 5 metres, and the cable operates from a single 3.3V supply drawn from the host connector. The operating temperature range is rated at -5°C to +70°C, and the assembly is RoHS compliant.

Buyers for this product are typically data centre operators, cloud service providers, and high-performance computing (HPC) facilities deploying 100G Ethernet or Infiniband EDR interconnects. Optech Technology Co., Ltd. manufactures from Taipei, Taiwan, with an address in the Neihu District, an area known for its concentration of electronics and networking hardware firms. Importers should confirm exact cable length requirements, jacket type, and host compatibility before placing orders, as passive copper cables are sensitive to signal integrity at longer lengths.

Optech Technology Co., Ltd. is headquartered at 5F, No. 56, Lane 258, Ruiguang Road in the Neihu District of Taipei City, Taiwan. Neihu is a well-established technology district hosting numerous electronics and networking hardware companies, giving the supplier proximity to Taiwan's broader ICT manufacturing ecosystem. The company is listed with an 'imported' supplier tier, indicating it operates as a distributor or trading entity rather than a direct factory manufacturer.

The supplier's trust tier is classified as 'harbor' on the platform, but its response rate is recorded at 0.00 with no average response time available. This means there is no historical data on how quickly the company responds to buyer inquiries. The listing provides detailed compliance references (SFF-8665, SFF-8679, IEEE 802.3bj) and specific performance figures, suggesting the company has technical familiarity with the product category, but buyers should verify manufacturing origin, warranty terms, and batch-level test documentation before placing volume orders.
