Description

StarTech J9281BST 1M 10G Direct Attach Cable

Overview

The StarTech J9281BST is a 1-meter passive twinax direct attach cable, fully compatible with HPE J9281B. This cable provides a cost-effective solution for short-reach 10 Gigabit Ethernet connections within racks or between adjacent racks. It's designed for environments requiring high-speed data transfer without the complexity or cost of fiber optics, making it suitable for server interconnects, network switch uplinks, and storage area networks. The J9281BST model offers a reliable 10Gbps link with minimal power draw.

Compatibility

This SFP+ direct attach cable is engineered to be 100% compatible with HPE networking equipment that utilizes SFP+ ports, including many ProLiant servers and FlexFabric switches. It is also broadly compatible with other network devices supporting SFP+ interfaces and 10GBASE-SR/LR standards, provided they adhere to industry specifications for SFP+ transceivers and DAC cables. The 100 Ohm impedance ensures signal integrity for 10Gbps data rates.

Installation Notes

This passive cable draws less than 0.1W per end, operating at 3.3V DC, and requires no configuration. Simply plug the SFP+ connectors into the corresponding ports on your network devices. The 30 AWG wire gauge ensures flexibility for routing within tight spaces. Operating temperature range is 0°C to 70°C, with storage temperatures from -40°C to 80°C.
