Blog Circa OPTCORE Launches Affordable 10G SFP DAC Cables for Network Upgrades

As data volumes grow exponentially, network latency and inefficient connectivity have become critical bottlenecks for businesses. While premium-branded SFP+ Direct Attach Copper (DAC) cables deliver performance, their high costs often strain IT budgets.

Optimized Performance for Demanding Networks

The 0.5-meter 10G SFP+ DAC cable provides a high-bandwidth, low-latency solution compatible with Cisco's SFP-H10GB-CU50CM specification. Engineered for modern high-speed environments, it supports multiple protocols including 10 Gigabit Ethernet (10GBase-CU), 8G Fiber Channel (FC), and 10G Fiber Channel over Ethernet (FCoE). This makes it suitable for diverse applications from enterprise data centers to virtualized environments.

Precision Engineering for Reliable Connectivity

Each cable undergoes rigorous testing to ensure compatibility with major network equipment brands. The I/O connectors are designed for high-speed differential signals with superior EMI/EMC performance, complying with Improved Pluggable Form Factor (IPF) standards. With a 3.3V power design and operational range of 0°C to 70°C, the cables maintain stability across various conditions while meeting RoHS environmental standards.

Technical Specifications

• OEM Compatibility: SFP-H10GB-CU50CM
• Data Rate: Up to 10.5Gb/s
• Cable Length: 0.5 meters (1.6 feet)
• Cable Type: Twinax twisted pair (30AWG)
• Connectors: SFP+/SFP+
• Operating Temperature: 0°C to 70°C
