Arista Networks C-O800-O800-1M Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top Passive Copper Twinax Cable, 1m (3ft)

The C-O800-O800-1M cable offers a direct OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) connection at 800Gbps. Its 1m (3ft) length and DAC construction are intended for Arista Networks equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: C-O800-O800-1MHT Part Number: C-O800-O800-1M

Product Highlights

• Compatible alternative to Arista Networks C-O800-O800-1M
• 800G connectivity at 800Gbps
• Interface configuration: OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)
• Fixed length and part number: 1m (3ft), C-O800-O800-1M
• Cable construction: Passive DAC
• Conductor specification: 30AWG
• Maximum power consumption: 0.1W Per End
• Minimum bend radius: 54mm

The listed modulation format is 8x100G-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.

This assembly uses 30AWG conductors, PET jacket, minimum bend radius 54mm. 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 800G Ethernet. Listed interface and protocol references include OSFP MSA, IEEE 802.3ck, CMIS v4.0. 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.

At 1m (3ft), C-O800-O800-1M 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.

C-O800-O800-1M occupies the middle of this family between C-O800-O800-0.5M at 0.5m (2ft) and C-O800-O800-1.5M at 1.5m (5ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The rated power consumption is 0.1W 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.

Compatibility is more than matching the OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) shape. This assembly is prepared for hosts expecting C-O800-O800-1M 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.

Quote HT part number C-O800-O800-1M with the required quantity. The 1m (3ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

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.
