PRODUCT PRESENTATION
The PHILISUN QSFP+ 40G CWDM4 10km LR4 LC DX transceiver is engineered for 40GBASE Ethernet connections, supporting up to 10 kilometers over single-mode fiber (SMF) at a 1310nm wavelength, using duplex LC connectors. It complies with QSFP+ MSA, IEEE 802.3ba 40GBASE-LR4, and OTU3 C4S1-2D1 standards. Additionally, it offers digital diagnostics through the I2C interface as outlined by the QSFP+ MSA, enabling real-time monitoring of operating parameters. This hot-swappable, easy-to-install transceiver is ideal for use in data centers, high-performance computing, and enterprise core and distribution networks.

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.
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 Figures 3 and 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 500mA.
