Product Description

The QSFP+ to 4x SFP+ Passive cable assemblies are high performance£¬cost effective for SFP+ and QSFP+ equipment interconnects . The Hybrid cables are compliant with SFF-8436 and SFF-8431 specifications. It is offer a low power consumption£¬short reach interconnect applications. The cable each lane is capable of transmitting data at rates up to 10Gb/s ,providing an aggregated rate of 40Gb/s.

Recommended Operating Conditions

QSFP+ Pin Descriptions

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 concurrent- ly. Requirements defined for the host side of the Host Edge Card Connector are listed in Table 6. Recommended host board power supply filtering is shown in Figure 4. Vcc Rx Vcc1 and Vcc Tx may be internally connected with- in the QSFP+ Module module in any combination. The connector pins are each rated for a maximum current of 500 mA.

SFP+ Pin Descriptions

VeeT

Transmitter Ground

1. Signals not supported in SFP+ Copper pulled-down   to VeeT with 30K ohms resistor

2. Passive cable assemblies do not support LOS and TX_DIS
