Connectivity Made Efficient and Easy

Approved Direct Attach Cables (DACs) fill the need for short, cost-effective connectivity and provide a power-efficient replacement to optical transceivers. Approved DACs are fully compliant with EEPROM and memory map requirements to assure proper system identification and interoperability. They are available in 1, 10, 16, 40, 56, 100, 112, 120 & 168GB ethernet, fiber channel and InfiniBand.

Passive Copper Cables

Approved's passive copper cables feature data rates from 1GB to aggregate rates up to 168GB of total bandwidth in distances up to 7 meters. They provide robust connections which require no power from the connector.

Form Factors: SFP, XFP, SFP+, XFP-SFP+, QSFP+, QSFP+ Breakout, CXP, CXP Breakout

Applications: High capacity I/O in Storage Area Networks, Network Attached Storage and storage servers. High bandwidth switches and routers. Data center cabling infrastructure and high-density connections between equipment.

Benefits: Support higher data rates than traditional copper interfaces. Ultra low crosstalk for improved performance. Low insertion loss. Rugged diecast covers protect the highly controlled wire termination area as well as deliver superior cable strain relief.

Active Copper Cables

Approved's active copper cables feature aggregate rates up to 168GB of total bandwidth and provide robust connections and require only 0.2W of power consumption while filling the need for short connectivity (up to 15 meters) in the data center.

Form Factors: SFP, XFP, SFP+, QSFP+, QSFP+ Breakout, CXP, CXP Breakout

Applications: Top-of-Rack (ToR) switch environments. High bandwidth switches and routers. Storage Area Networks (SAN), Network Attached Storage (NAS) and servers.

Benefits: Ultra low crosstalk for improved performance. Low insertion loss. Low power. Cost effective solution to optical modules. Thinner and lighter than passive copper. Circuits draw power only at each end.

Active Optical Cables

Approved's Active Optical Cables (AOC) feature aggregate rates up to 168GB of total bandwidth and are ideal for the high-density signal transmission seen in most data centers and high performance computing applications. Approved AOC's currently offer cable lengths up to 300 meters and consume less than 2W per connection on a 120GB CXP end.

Form Factors: SFP+, QSFP+, QSFP+ Breakout, CXP, CXP Breakout

Applications: Rack-to-rack, shelf-to-shelf interconnection of data center hubs, switches, routers, servers and storage systems.

Benefits: Bit Error Rate (BER) is 1000x better than copper cables. 3-4x lighter than copper cables with a tighter bend radius. Typical power (275 mW per end) is 1/3 the wattage of a SFP+ transceiver with improved EMI.
