H3C LSTM2STK Compatible 10G SFP+ Passive Copper Twinax Cable, 7m (23ft)
For a direct equipment connection requiring H3C LSTM2STK, this page supplies the 7m (23ft) version with SFP+ to SFP+. The cable supports 10G operation and eliminates a separate module-and-patch-cord assembly. Installation, maintenance and spare-cable identification are addressed alongside the full technical details.

Power and Thermal Planning
The rated power consumption is ≤0.1W. 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.
Length Selection and Installation Planning
The installation review for a 7m (23ft) link should include pathway length, support points, connector access and future maintenance. Route the complete copper assembly and both connector housings before attaching both ends, and avoid dragging it across connector panels. A final inspection should confirm that no latch, boot or jacket section carries unnecessary strain. The next shorter verified assembly is LSTM1STK at 5m (16ft), which is the better comparison when the managed route leaves substantial unused cable.
Position Within the Length Range
LSTM2STK is the longest of 5 verified length options in this family. Compared with LSTM1STK at 5m (16ft), it provides 2m 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.
Field Installation and Maintenance
Inspect the route and both connectors before installation, then support the cable without pulling on either connector housing. During maintenance, release the latch properly rather than using the cable as a handle. Keep protection on unused ends, and if the assembly is removed for later use, coil it loosely and record its part number so the same length can be returned to service. For this assembly, the listed conductor specification is 24AWG; the minimum bend radius is 30mm; the stated power consumption is ≤0.1W; the jacket material is PVC (OFNR).
Cable Construction and Routing
This assembly uses 24AWG conductors, PVC (OFNR) 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 10G Ethernet. Listed interface and protocol references include 1x InfiniBand QDR, DDR, SDR, 10 Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.
Passive Copper Operation
A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.
Quality Assurance and Packaging
The cable and both connectors are inspected before a functional link test. Connector protection and bend-safe packing reduce handling damage during transport and storage. Customer or site labels can be added for field inventories, with different lengths separated to simplify issue and return of spare assemblies. Volume orders can include customer references on the labels and carton list.
H3C Compatibility and Factory Testing
A field-ready cable needs both correct identification and a stable operating link. Our pre-packing check therefore includes the connectors, host recognition and link behavior. For equipment with uncertain revision history, providing the host model and software release helps identify compatibility requirements before the assembly reaches the installation site. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
Frequently Asked Questions
Is this an original H3C cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies H3C LSTM2STK.
Does this order code cover multiple lengths?
No. LSTM2STK 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.
Ordering Information
Request the cable by its exact part number and length, and state the equipment model if compatibility confirmation is needed. Site orders can list quantities by rack or installation team. Any requested label should retain the part number so a removed or spare cable can still be identified accurately. Keep LSTM2STK associated with 7m (23ft) throughout the order and receiving record.
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.
