Purpose This document validates solely for the product of UMEC 40-Gbps QSFP+ to 4×10-Gbps SFP+ Break-Out Active Optical Cable (AOC) product specification. This document provides basic information and electronic characteristics for customer reference only, and subjects to change without notice. 2. General Description UMEC’s 40-Gbps QSFP+ to 4×10-Gbps SFP+ Break-Out AOC allows interoperable connections between a 40Gbps QSFP+ port and 4 separate 10Gbps SFP+ ports, enabling the flexible linkage of servers, switches, or storages with different port interfaces. This AOC is of high-performance with full-duplex and aggregate 40-Gbps. Compared with conventional copper cables, longer, lighter, and flexible AOCs makes the ease of complicated data-center cablings because of its small cable diameter of only 3-mm. High-quality 850-nm VCSELs and PIN PDs are adopted in this AOC cable with superior signal integrity and link performance, bringing reliable operation performance. 3.

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. 2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently. 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 within the QSFP+ module in any combination. The connector pins are each rated for a maximum current of 500 mA.

Handling Care should be taken to restrict exposure to the conditions defined in the Absolute Maximum Ratings. Put the product in an even and stable location. If the product falls down or drops, it may cause an injury or malfunction. The cable must not be subject to extreme bends during installation or while in operation. If you bend the cable at a radius less than the cable minimum bend radius, then the cable may get damaged. Don’t twist or pull by force ends of the cable, which might cause malfunction.
