QSFP-40G-4LCAO-5M16FT 40G QSFP+ to 4 Duplex LC Active Optical Breakout Cable, 5m (16ft)

The QSFP-40G-4LCAO-5M16FT cable on this page is the 5m (16ft) version for Generic hosts requiring 40G operation. Its QSFP+ to 4 duplex LC AOC construction reduces the connection to one factory-terminated assembly. Related lengths, brand cross-references and rack-integration notes support a precise high-density deployment.

Cable Construction and Routing
This assembly uses OFNP jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 10G/40Gigabit Ethernet or Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The QSFP+ to 4 duplex LC configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.
Integrated Optical Assembly
The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.
Length Selection and Installation Planning
The 5m (16ft) length gives QSFP-40G-4LCAO-5M16FT more freedom for adjacent-rack and row-end deployments. The integrated optical assembly should be supported along its route without tight bends or connector pull loads; the AOC specification and host support must still match the intended link.
Position Within the Length Range
QSFP-40G-4LCAO-5M16FT is the shortest of 5 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is QSFP+ to 4 duplex LC-40G-AOC-10M33FT at 10m (33ft), adding 5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
High-Density Rack Integration
In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the minimum bend radius is 30mm; the jacket material is OFNP.
Quality Assurance and Packaging
Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Neutral packaging and customer-specific packing documentation are available on request.
Ordering Information
Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. Keep QSFP-40G-4LCAO-5M16FT associated with 5m (16ft) throughout the order and receiving record.
Generic Compatibility and Factory Testing
The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
Frequently Asked Questions
Is this an original equipment manufacturer cable?
No. It is manufactured by HT under our own manufacturer identity.
How should an unused assembly be stored?
Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.
Can different brands be connected with the same assembly?
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
Does this order code cover multiple lengths?
No. QSFP-40G-4LCAO-5M16FT refers here to 5m (16ft). Every other verified length has a separate part number and page in the length list.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production quantities confirmed at order stage. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
