Direct Attach SFP+ Cable BlueOptics 10GBASE-CR SFP+ to SFP+ 2 m AWG30 (980-9I688-00J002-BL)

BlueOptics direct attach passive SFP+ cable provides a compact, low-latency copper connection for 10GBASE-CR links between SFP+ ports. This 2 m AWG30 twinax assembly is intended for short-reach 10 Gbit/s interconnects in data center environments, enabling direct SFP+ to SFP+ connection without separate transceiver modules. The cable is designed for use with switches, servers and storage devices where a reliable, plug-and-play copper link is required for rack-to-rack or within-rack configurations.

Advantages

The cable delivers a cost-effective and power-efficient alternative to fiber plus transceivers for short distances, with low latency and predictable electrical performance. Its fixed-length twinax construction reduces clutter and simplifies installation compared with using separate SFP+ transceivers and fiber or active cables. The 2 m length provides flexibility for typical rack spacing while maintaining signal integrity over the specified reach.

Suitable for

• 10 Gbit/s direct connections between SFP+ ports on switches and routers
• Server-to-switch and storage-to-switch interconnects within racks
• Short-reach data center links where passive twinax is acceptable

Key specifications

• Data rate: 10 Gbit/s (10GBASE-CR)
• Connector type: SFP+ to SFP+
• Cable type: Passive twinax (AWG30)
• Length: 2 meters
• Latency: low, suitable for latency-sensitive applications
• Installation: plug-and-play, no external power required

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your networking equipment until the latch engages. Ensure both devices support passive SFP+ direct-attach copper connections and 10GBASE-CR operation. Avoid sharp bends and maintain recommended bend radius for AWG30 twinax to preserve signal quality. No drivers or configuration changes are typically required; the link will negotiate at 10 Gbit/s if both ends support the standard.

Usage recommendations

Use this passive SFP+ cable for short-distance connections within racks or between adjacent racks. Verify compatibility with equipment vendors if vendor-locking or compatibility lists are a concern. For distances beyond the specified reach or where optical isolation is required, consider fiber with transceivers or active optical cables.
