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
Measure twice before deploying this 20m (66ft) cable: once along the planned route and again after accounting for service access. The objective is adequate reach without a concealed surplus. Support the integrated optical cable and both optical engines, preserve front-panel clearance and check that nearby power cords or sharp hardware cannot damage the jacket. Within this family, QSFP+ to 4 duplex LC-40G-AOC-15M49FT is shorter at 15m (49ft), while QSFP+ to 4 duplex LC-40G-AOC-30M98FT is the next longer choice at 30m (98ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
QSFP+ to 4 duplex LC-40G-AOC-20M66FT occupies the middle of this family between QSFP+ to 4 duplex LC-40G-AOC-15M49FT at 15m (49ft) and QSFP+ to 4 duplex LC-40G-AOC-30M98FT at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 10m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.
Structured Pathways and Serviceability
Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. For this assembly, the minimum bend radius is 30mm; the jacket material is OFNP.
Ordering Information
Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. Keep QSFP+ to 4 duplex LC-40G-AOC-20M66FT associated with 20m (66ft) throughout the order and receiving record.
Generic Compatibility and Factory Testing
Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
Shipping and Lead Time
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
Quality Assurance and Packaging
After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Standard protective packing is used by default, with project documentation arranged when requested.
Frequently Asked Questions
Is this an original equipment manufacturer cable?
No. It is manufactured by HT under our own manufacturer identity.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
What details assist a compatibility review?
Provide the equipment manufacturer, model, port type, hardware revision and software release, together with the OEM reference, required length and quantity.
