QSFP28 to 4 duplex LC-100G-AOC-70M230FT 100G QSFP28 4 x 25G NRZ to 4 Duplex LC 25G NRZ Active Optical Breakout Cable, 70m (230ft)
For buyers working from an equipment parts list, QSFP28 to 4 duplex LC-100G-AOC-70M230FT identifies more than a connector style. It refers here to a 70m (230ft) AOC cable for Generic hosts, supporting 100G operation with QSFP28 to 4 duplex LC. The sections below separate the OEM cross-reference, physical specification and HT factory checks for straightforward purchasing review.

Signal and Lane Configuration
The listed modulation format is QSFP28-4x 25G-NRZ Duplex LC-1x 25G-NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.
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
A 70m (230ft) run can remain tidy when its pathway and service allowance are planned together. Keep the integrated optical cable and both optical engines away from tight cable-tie pressure, verify bend control at changes of direction and ensure that neither port supports the assembly’s weight. Record the exact order code after acceptance. The next shorter verified assembly is QSFP28 to 4 duplex LC-100G-AOC-50M164FT at 50m (164ft), which is the better comparison when the managed route leaves substantial unused cable.
Position Within the Length Range
QSFP28 to 4 duplex LC-100G-AOC-70M230FT is the longest of 11 verified length options in this family. Compared with QSFP28 to 4 duplex LC-100G-AOC-50M164FT at 50m (164ft), it provides 20m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. For this assembly, the minimum bend radius is 20mm; the stated power consumption is 2.2W; the jacket material is OFNP.
Power and Thermal Planning
The rated power consumption is 2.2W. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.
Cable Construction and Routing
This assembly uses OFNP jacket, minimum bend radius 20mm. 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 SFF-8436, SFF-8431. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The QSFP28 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.
Generic Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
Ordering Information
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. Quantity and any labeling instructions should be attached specifically to QSFP28 to 4 duplex LC-100G-AOC-70M230FT.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. 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.
Does this order code cover multiple lengths?
No. QSFP28 to 4 duplex LC-100G-AOC-70M230FT refers here to 70m (230ft). Every other verified length has a separate part number and page in the length list.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
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.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. 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.
