SFP112 to SFP112-100G-DAC-0.5M2FT 100G SFP112 PAM4 Passive Copper Twinax Cable, 0.5m (2ft)
For buyers working from an equipment parts list, SFP112 to SFP112-100G-DAC-0.5M2FT identifies more than a connector style. It refers here to a 0.5m (2ft) DAC cable for Generic hosts, supporting 100G operation with SFP112 to SFP112. 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 100G-PAM4 to 100G-PAM4. 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.
Cable Construction and Routing
This assembly uses 28AWG conductors, PVC (OFNR) 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 100G Ethernet.
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.
Length Selection and Installation Planning
The 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing SFP112 to SFP112-100G-DAC-0.5M2FT; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.
Position Within the Length Range
SFP112 to SFP112-100G-DAC-0.5M2FT is the shortest of 5 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 SFP112 to SFP112-100G-DAC-1M3FT at 1m (3ft), adding 0.5m 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 28AWG; the minimum bend radius is 20mm; the stated power consumption is <0.15W; the jacket material is PVC (OFNR).
Power and Thermal Planning
The rated power consumption is <0.15W. 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.
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. 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. This page’s fixed configuration is 0.5m (2ft); another length must be quoted under its corresponding part number.
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. SFP112 to SFP112-100G-DAC-0.5M2FT refers here to 0.5m (2ft). 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
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. 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.
