PRODUCT PRESENTATION

The PHILISUN QSFP-DD 400G (4x100G) 1310nm 10km LR4 LC DX Transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-Double Density (QSFP-DD) optical module designed for optical communication over distances up to 10km. This module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 CWDM optical signals, multiplexing them into a single channel for 400Gb/s optical transmission. On the receiver side, it de-multiplexes the 400Gb/s optical input into 4 CWDM optical signals and converts them back into 8 channels of 50Gb/s (PAM4) electrical output.The 4 CWDM channels have central wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm, as defined by the CWDM wavelength grid in ITU-T G.694.2. The transceiver features a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To ensure optimal performance over long distances, single-mode fiber (SMF) must be used.Additionally, host Forward Error Correction (FEC) is required to support transmission distances of up to 10km.This module is designed for reliability and efficiency, making it an ideal solution for high-speed, long-range optical communication in advanced network systems.

PRODUCT PRESENTATION

The PHILISUN QSFP-DD 400G (4x100G) 1310nm 2km FR4 LC DX transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for optical communication applications over distances of up to 2km. The module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 CWDM optical signals, multiplexing them into a single channel for 400Gb/s optical transmission. On the receiver side, it de-multiplexes a 400Gb/s optical input into 4 CWDM optical signals and converts them back into 8 channels of 50Gb/s (PAM4) electrical output.The 4 CWDM channels operate at central wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm, as defined by the CWDM wavelength grid in ITU-T G.694.2. The transceiver features a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To ensure minimal optical dispersion over long distances, single-mode fiber (SMF) is required for this module. Host Forward Error Correction (FEC) is also necessary to support transmission over 2km.With its advanced design and adherence to industry standards, this transceiver is an ideal solution for high-speed, long-range optical communication applications.

PRODUCT PRESENTATION

The PHILISUN QSFP-DD 400G (4x100G) 1310nm 500m DR4 MPO8/12 Transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module, ideal for optical communication applications over distances of up to 500m. The module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 parallel optical signals, each supporting 100Gb/s, for a total data rate of 400Gb/s. On the receiver side, it reverses the process, converting 4 channels of 100Gb/s optical signals back into 8 channels of 50Gb/s (PAM4) electrical output.The module is compatible with MTP/MPO-12 connector optical fiber cables, ensuring precise alignment through guide pins inside the receptacle. To maintain proper channel-to-channel alignment, the cable should not be twisted. Electrical connectivity is achieved via an edge-type connector compliant with the QSFP-DD MSA standard.Designed with a compact form factor, robust optical and electrical connections, and a digital diagnostic interface, this transceiver is a reliable solution for high-speed, short-range data communication applications.

PRODUCT PRESENTATION

The PHILISUN QSFP28 100G LAN-WDM 40km ER4 LC DX is a high-performance 100Gb/s transceiver module designed for optical communication applications compliant with the Ethernet 100GBASE-ER4 standard. It converts four 25Gb/s electrical input channels into four LAN WDM optical signals, multiplexing them into a single channel for 100Gb/s optical transmission. On the receiver side, it de-multiplexes the 100Gb/s optical input back into four LAN WDM optical signals and converts them into four electrical output channels.The central wavelengths of the four LAN WDM channels are 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm, consistent with the LAN WDM wavelength grid defined in IEEE 802.3ba. Equipped with high-performance cooled LAN WDM DFB transmitters and high-sensitivity APD receivers, the module ensures exceptional performance for 100Gigabit Ethernet applications over links up to 40km.Designed according to the QSFP+ Multi-Source Agreement (MSA), the transceiver features a compact form factor, reliable optical/electrical connections, and a digital diagnostic interface. Built to withstand extreme operating conditions, including high temperatures, humidity, and EMI interference, it ensures robust and reliable performance in demanding environments.
