H3C LSWM1QSTK7A Compatible 40G QSFP+ Active Copper Cable, 7m (23ft)
The LSWM1QSTK7A compatible assembly is intended for H3C equipment that requires a 40G direct-attached connection. This version is specifically 7m (23ft), with QSFP+ to QSFP+ and its own order reference. Exact length pages and equivalent brand references are linked to make multi-product procurement easier to verify.

Cable Construction and Routing
This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 37.5mm. 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.
Length Selection and Installation Planning
A 7m (23ft) run can remain tidy when its pathway and service allowance are planned together. Keep the complete copper assembly and both connector housings 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 verified reach is LSWM1QSTK10A at 10m (33ft), but selecting it before measuring the route would introduce additional slack to support.
Position Within the Length Range
LSWM1QSTK7A is the shortest of 2 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 LSWM1QSTK10A at 10m (33ft), adding 3m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
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 listed conductor specification is 26AWG; the minimum bend radius is 37.5mm; the jacket material is PVC (OFNR).
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.
H3C 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. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.
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 LSWM1QSTK7A.
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 H3C cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies H3C LSWM1QSTK7A.
Does this order code cover multiple lengths?
No. LSWM1QSTK7A refers here to 7m (23ft). 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. 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.
