H3C LSTM2STK Compatible 10G SFP+ Passive Copper Twinax Cable, 7m (23ft)

With a fixed 7m (23ft) cable and SFP+ to SFP+, the LSTM2STK compatible assembly simplifies 10G deployment. It is manufactured and tested by HT for H3C equipment.

OEM Part Number: LSTM2STKHT Part Number: LSTM2STK

Product Highlights

• Compatible alternative to H3C LSTM2STK
• 10G connectivity at 10Gbps
• Interface configuration: SFP+ to SFP+
• Fixed length and part number: 7m (23ft), LSTM2STK
• Cable construction: Passive Twinax
• Conductor specification: 24AWG
• Maximum power consumption: ≤0.1W
• Minimum bend radius: 30mm

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.

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.

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.

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.

The extended 7m (23ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated DAC construction avoids a chain of separate modules and patch leads.

The assembly is configured for equipment that recognizes LSTM2STK. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

When ordering, specify LSTM2STK, cable length 7m (23ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
