For densely populated equipment, the fixed 1m (3ft) version of Generic OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-1.6T-ACC-1M3FT offers a clearly defined 1.6T link without separate optical modules or patch cords. The ACC assembly uses OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top); its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

Signal and Lane Configuration
The listed modulation format is 8x 200G-PAM4 to 8x 200G-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.
Network and Protocol Considerations
The intended application is 1.6T Ethernet. Listed interface and protocol references include OSFP Rev 5.2, CMIS 5.0, IEEE 802.3df and 802.3dj. Confirm that the host firmware and port configuration support the same operating mode.
Length Selection and Installation Planning
At 1m (3ft), OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-1.6T-ACC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.
Position Within the Length Range
OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-1.6T-ACC-1M3FT 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 OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-1.6T-ACC-2M7FT at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
High-Density Rack Integration
In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the listed conductor specification is 25AWG; the minimum bend radius is 60mm; the stated power consumption is 2.5W Per End; the jacket material is LSZH.
Power and Thermal Planning
The rated power consumption is 2.5W Per End. 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.
Cable Construction and Routing
This assembly uses 25AWG conductors, LSZH jacket, minimum bend radius 60mm. 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.
Quality Assurance and Packaging
Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Standard protective packing is used by default, with project documentation arranged when requested.
Ordering Information
Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. This page’s fixed configuration is 1m (3ft); another length must be quoted under its corresponding part number.
Generic Compatibility and Factory Testing
The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
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. OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-1.6T-ACC-1M3FT refers here to 1m (3ft). 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 normally prepared for dispatch within one to three working days, while larger production requirements are scheduled 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.
