1. Product Description
The NASACVR-QSFP-SFP10G Module offers 10 Gigabit Ethernet connectivity for Quad Small Form-Factor Pluggable (QSFP)-only platforms. It allows smooth and cost- effective migration to 40 Gigabit Ethernet by providing an option to use lower-speed Enhanced Small Form-Factor Pluggable (SFP+) modules in empty QSFP ports or when the other end of the network is running at lower speeds.
The NASACVR-QSFP-SFP10G Module is individually tested on corresponding equipment such as Cisco, Palo Alto, Juniper, Dell, HP, IBM, Nokia, Alcatel Lucent…. switches, routers, firewall, servers, network interface card (NICs) etc., and passes the monitoring of NASA-SI intelligent quality control system.
The NASACVR-QSFP-SFP10G Module converts a QSFP port into an SFP+ port. With this adapter, customers have the flexibility to use any SFP+ module or cable to connect to a lower-speed port on the other end of the network. This flexibility allows a cost-effective transition to 40 Gigabit Ethernet by maximizing the use of high-density 40 Gigabit Ethernet QSFP platforms. This adapter supports all SFP+ optics and cable reach. Compatible Switch Models and SFP+ Modules. A list of SFP+ transceiver modules that can be plugged into the QSA module is provided in Table.

Note:
1. GND is the symbol for signal and supply (power) common for QSFP modules. All are common within the QSFP module and all module voltages are referenced to this potential otherwise noted. Connect these directly to the host board signal common ground plane 2.cc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown below. Vcc Rx, Vcc1 and 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 500mA.

Notes:
- The module signal grounds, VeeR and VeeT, shall be isolated from the module case.
- This is an open collector/drain output and shall be pulled up with 4.7-10k to Vcc_Host on the host board. Pull ups can be connected to multiple power supplies, however the host board design shall ensure that no module has voltage exceeding module VccT/R + 0.5 V.
- This is an open collector/drain input and shall be pulled up with 4.7-10k to VccT in the module.
- See 2-wire electrical specifications.
