Import Active Optical Cables(Aoc) — Buy in Bulk from Supplier in China

The 40G QSFP+ to 4xSFP+ Active Optical Cable from Ousent Technologies Co., Ltd is a plug-and-play optical interconnect designed for high-speed data centre and enterprise network environments. It transmits at a 40 Gbps data rate over an 850 nm multimode wavelength, converting electrical signals to optical within the transceiver housing to eliminate the need for separate transceivers and fibre patch cords. Cable assemblies are available in lengths up to 100 metres, giving architects flexibility in rack-to-rack and row-to-row deployments without the signal integrity limits of copper DACs.

The cable integrates four full-duplex 10 Gbps channels, each operating at 10.3125 Gbps per lane with 64b/66b encoding. The construction uses OM3 or OM4 multimode fibre with standard bend-insensitive cladding, terminated in a QSFP+ MSA-compliant housing on the host side and four individual SFP+ housings on the break-out end. Power consumption is typically under 1.5 W for the full assembly, a fraction of the 3-4 W consumed by equivalent copper solutions at this bandwidth. The optical engine employs vertical-cavity surface-emitting laser (VCSEL) arrays and PIN photodiode receivers, with digital diagnostic monitoring (DDM) accessible via the I2C management interface per SFF-8436 and SFF-8431 specifications.

Primary buyers include hyperscale data centre operators, telecommunications carriers rolling out 5G fronthaul, and systems integrators building high-performance computing clusters. Typical applications include spine-leaf fabric interconnects, storage area network links, and broadcast video transport where low latency and electromagnetic immunity are critical. Buyers should confirm the exact cable length, fibre grade (OM3 versus OM4), and whether the firmware revision supports their switch vendor's cable identification protocol before committing to volume orders.

Ousent Technologies Co., Ltd is headquartered in Shenzhen, Guangdong Province, with its registered address at 201, West Block 1, Shunheda Industrial Zone in the Nanshan District Hi-Tech Park. The supplier is classified as an imported-tier account on the platform with a harbour trust tier, indicating a baseline verification level rather than advanced third-party audit status. The listing provides no information about factory certifications, ISO accreditation, or in-house versus outsourced manufacturing, so buyers should treat quality claims as unverified until documentation is requested directly.

The supplier profile shows a response rate of 0.00 and an average response time of zero hours, which signals either a newly activated account or inactive sales pipeline rather than a closed business. No employee count, annual revenue, or major client references appear in the available data. Buyers initiating contact should request a current capability statement, recent test reports for the specific AOC part number, and clarification on whether Ousent operates its own fibre-termination clean room or sources finished cable assemblies from upstream partners.
