Product Overview:

The DM-383-XXX QSFP+ to 4* SFP+ Direct Attach cable assembly is a high performance integrated

duplex data link for bi-directional communication over copper cable for lengths up to 7m. It is

compliant with the IPF MSA (SFF-8432) and QSFP+ 10 Gbs 4X MSA (SFF-8436) for mechanical

form factors and SFP+ MSA (SFF-8431 Appendix E) for direct attach cables. It is data rate agnostic

and supports speeds of up to 10Gbps. The DM-383-XXX provides a cost effective alternative to

optical links.

1. Labeling as inputs (I) and outputs (O) are from the perspective of the module

2. The module signal ground contacts, VeeR and VeeT, shall be isolated from the module case.

3. This contact is an open collector/drain output contact and shall be pulled up on the host.

4. TX_Disable is an input contact with a 4.7-10 kΩ pullup to VccT inside the module.

5. Serial Clock and Data line to access Serial ID specified in Table 2.

6. Pulled Low to Veet with 33K resistor in the module.

Note 1: GND is the symbol for signal and supply (power) common for the QSFP+ module. All are

common within the QSFP+ module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the

host board signal-common ground plane.

Note 2: Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently. Vcc Rx, Vcc1and Vcc Tx

may be internally connected within the QSFP+ transceiver module in any combination. The connector pins are each rated for a maximum current

of 500 mA.
