H3C LSWM3STK Compatible 10G SFP+ Passive Copper Twinax Cable, 3m (10ft)

The LSWM3STK cable offers a direct SFP+ to SFP+ connection at 10Gbps. Its 3m (10ft) length and DAC construction are intended for H3C equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: LSWM3STKHT Part Number: LSWM3STK

Product Highlights

• Compatible alternative to H3C LSWM3STK
• 10G connectivity at 10Gbps
• Interface configuration: SFP+ to SFP+
• Fixed length and part number: 3m (10ft), LSWM3STK
• Cable construction: Passive Twinax
• Conductor specification: 30AWG
• Maximum power consumption: ≤0.1W
• Minimum bend radius: 23mm

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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

LSWM3STK occupies the middle of this family between LSWM2STK at 1m (3ft) and LSTM1STK at 5m (16ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 23mm. 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.

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.

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.

Compatibility is more than matching the SFP+ to SFP+ shape. This assembly is prepared for hosts expecting LSWM3STK and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as LSWM3STK in 3m (10ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
