Direct-Attach Cables

DAC

Direct-Attach Cables (DAC) are cost efficient close-range interconnection media widely used in telecom operator equipment rooms, data centers and corporate networks for connecting LAN and SAN equipment in same or neighboring racks. Our multi-vendor compatible Direct-Attach Cables portfolio support full range of transmission speeds from 10 Gbps up to 100 Gbps applications, customizable length of cables and current most popular interface assembly form factors – QSFP and SFP. Our multi-vendor compatible Direct-Attach Cables portfolio is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules. However – we can provide Direct-Attach Cables with custom-encoded firmware in order to make it work almost in any equipment and we can support encoding of each end to support different vendor equipment, allowing using Direct-Attach Cables as cross-platform interconnection medium.

Passive Twinax (Copper) Direct Attach Cables:

Passive Twinax (Copper) Direct Attach Cables are popular and cost effective inter-connection media allowing interconnecting different data transmission equipment within equipment room or data center. Passive Direct Attach Cables are equipped with MSA standards compatible transceiver copper assembly at each end of cable allowing to use legacy transceiver ports, however connection is pure electrical without electrical-optical signal conversation. Passive Twinax cables are fully passive and provide no electrical signal re-generation or boosting, therefore DAC cables have minimal power consumption, but maximal distance is limited up to 5m. Different Passive DAC cables provide transmission speed in range of 10-100 Gbps and support all most popular LAN and SAN applications:

Active Twinax (Copper) Direct Attach Cables:

Active Twinax (Copper) Direct Attach cables are similar to passive ones – main difference distinguishing active Twinax cable from similar passive twinax is that this assembly is equipped with chip-sets performing regeneration and boosting electrical signal translated over copper lanes, thus allowing reaching greater distances via copper media and not losing transmission quality. Active Twinax cables compared with passive ones are more expensive and have higher power consumption – this is because of implemented electrical signal boosting and re-generation chipsets. Different Active DAC cables provide transmission speed in range of 10-100 Gbps and support all most popular LAN and SAN applications:

Active Optical (AOC) Direct Attach Cables:

Active Optical (AOC) Direct Attach Cables compared to Twinax (Copper) cables provides much higher reach up to 100m, as it provides electrical-optical signal conversation, but same time lower power consumption as conventional optical transceivers. AOC have also lower weight and thinner cable and bend radius as Twinax (Copper) cables. These properties makes AOC direct attach cables favored choice of interconnection media in cases when distance is more than 10m. Different Active Optical (AOC) DAC cables provide transmission speed in range of 10-100 Gbps and support all most popular LAN and SAN applications:
