OEM Compatible Direct Attach, Active Copper & Active Optical Cables

1 OEM Compatible Direct Attach, Active Copper & Active Optical Cables An introduction and Comparison of Direct Attach Cables, Active Copper Cables and Active Optical Cables Cables are often used for data centre short reach interconnects. They are terminated with transceiver-style plugs to be used in the same ports where optical transceiver are used. Protocol independent, can support Ethernet, Infiniband, Fiber channel, etc. ProLabs range of Direct Attach Cooper Cable Assembly are based on 10G Ethernet IEEE 802.3ae standard. Cables can be divided into 3 families: (DAC) Copper Direct Attach Cable (ACC) Active Copper Cables (AOC) Active Optical Cables Product Features Up to 11 GBd bi-directional data links Compliant with 10GFC Compliant with SFF8431 Hot-pluggable SFP+ footprint AC coupled inputs and outputs 100 Ohm differential impedance Enhanced EMI design Single power supply 3.3V RoHS Compliance Operating temperature range: 0º C to 70ºC OR ProLabs DACs are compatible with the following manufacturers Alcatel Arista Brocade-Foundry Cisco Enterasys Extreme Force 10 HP Huawei H3C Juniper Mellanox

2 Cables are available with SFP+ termination (10G ports), QSFP+ (40G) and hybrid (QSFP+ to 4x SFP+) In principle, cables can be realized with any transceiver form factor (CXP, CX4, etc.) Comparison Matrix DAC ACC AOC Cost $ $$ $$$ Power Low Medium Med-High Distance 7m* 15m 300m Weight High High Low Cable Stiffness High High Low Product Features DAC cables are a cost effective interconnection option for short distance networking applications. AOC are a premium product, offering several benefits over copper (reach, weight, bendflexibility) DAC & AOC use the same port as an optical transceiver but with significant cost and power savings in short reach applications. *Can be up to 10m for data rates < 10Gbps Copper Cable Sizes 1) 2) 3) 4) 1) Fiber 10/40/100G 2) 10G cable 2 pairs 10/40/100G 3) 40G cable 8 pairs 10/40/100G 4) 100G cable 20 pairs 10/40/100G Weight: A 5 meter 10G copper cable weighs approximately 1Kg while an AOC is approximately 250g An AOC can be a quarter of the weight of a copper cable (DAC/ ACC) for equal cable lengths 100G cables theoretically possible but in reality done with AOC The ProLabs Advantage Compatibility 100-percent compatible with more than 40 vendors and 20,000 systems Quality At the forefront of technology development, coding, testing & customisation with lifetime warranty on transceivers & cables. Service Fast, responsive, knowledgeable service and support that exceeds that of OEMs Global Large inventory in US and Europe means fast shipping to more than 40 countries monthly Cost-effective Savings of up to 70 percent
