Brand:
Juniper

Specifications

        Product details:
  • 100% brand new from factory and high quality
  • Economical Price
  • Sold and shipped from Singapore (hence faster delivery, Easy to Exchange)
  • 1 Year Warranty
  • Brand: Juniper 
  • Model: QFX-QSFP-DAC-3M

    Technical Specifications:
  • Part Number: 740-038624
  • Speed: 40 Gigabit Ethernet (40 Gbps)
  • Transceiver Type: QSFP+ (Quad Small Form-factor Pluggable Plus)
  • Product Type: Direct Attach Copper (DAC)
  • Connector: None (Transceivers are permanently attached to the cable)
  • Breakout Capable: No (The cable does not support breakout, meaning it only connects point-to-point for 40G connections)
  • Cable Type: Direct Attach Copper (DAC) – no fiber involved, uses copper cables for short-range high-speed transmission
  • Distance: 3 meters maximum (this cable is designed for short-range connections)
  • Signaling Rate: 40 Gbps full-duplex serial transmission per lane (each of the four lanes transmits at 10 Gbps)
  • Wire AWG: 30 AWG (this is the wire gauge used in the cable; it’s relatively thin for high-density, short-distance connections)
  • Monitoring Available: Yes (Digital Optical Monitoring or DDM is available for real-time monitoring of the transceiver’s status, though this feature is generally more common with fiber transceivers, not DAC cables)
  • Standard: QSFP-DAC (QSFP Direct Attach Copper standard)

    Power and Temperature Specifications:
  • Maximum Power Consumption: 0.5 W (this is a very low power consumption, typical for DAC cables)
  • Operating Temperature Range: -40°C to 85°C (this wide temperature range allows the cable to operate in harsh environments, such as outdoor data centers or industrial settings)
  • Storage Temperature Range: -40°C to 85°C

    Key Features:
  • QSFP+ Form Factor: The QSFP+ transceiver is used for 40G Ethernet connections. It supports 4 lanes, each capable of 10 Gbps, for a total of 40 Gbps bandwidth.
  • DAC (Direct Attach Copper): This type of cable is ideal for short-range, high-speed connections typically found in data centers, where distances of up to 3 meters are common between devices such as switches, servers, and storage arrays.
  • No Fiber: Unlike optical cables, DAC cables use copper wiring for high-speed data transmission over short distances. This makes them more cost-effective and easier to install in environments where fiber optic cabling is not necessary.
  • Digital Monitoring: While DAC cables typically don’t require optical monitoring like fiber optic cables, this particular cable offers digital monitoring capabilities, which allows users to check the operational status of the cable and transceiver.

    Use Cases:
  • This QSFP+ DAC cable is commonly used in high-performance networking environments such as:
  • Data centers for connecting switches, routers, servers, and storage devices within short distances (up to 3 meters).
  • High-density applications where the cost of fiber optics may not be justified for short links, but high-speed 40G connections are needed.
  • Server-to-switch connections, rack-to-rack connections, or server-to-server interconnects where the cable length is within the 3-meter range
