Product Description:
E-link's LNK-AA4CMX-XXX series are an active optical cable (AOC)
ideal for high-throughput data networks requiring fast, reliable
connections. Advantages of this product include:
- High speed: it allows for bi-directional 40Gbps transmission
suitable for Ethernet 40GBASE-SR4 and InfiniBand QDR applications.
- High density
- Low latency
- Low power consumption
- Light weight
These features make the LNK-AA4CMX-XXX series the perfect choice
for data-intensive environments.
Features:
The Quad Small Form-factor Pluggable (QSFP) is a 40GBASE-SR4
compliant. It is compliant with QDR, DDR, SDR (Infiniband) and
capable of bi-directional parallel link. Its transmission rate is
10.3125Gb/s per lane, x4 channels and is up to 100m in length.
Furthermore, it offers low power consumption and two types of
connectors, low profile connectors and electrical 38-pin
connectors. It also has a bundle of multi-mode fiber array, 850nm
VCSEL four array and PIN diode four array. The I2C management
interface ensures that the device is able to stand from 0 to 70
degree case temperature. The power supply voltage used for this
device is 3.3V.
Technical Parameters:
These values represent the damage threshold of the module. Stress
in excess of any of the individual Absolute Maximum Ratings can
cause immediate catastrophic damage to the module even if all other
parameters are within Recommended Operating Conditions.
