PRODUCT PRESENTATION

The PHILISUN QSFP56 200G (4x50G) CWDM4 10km LR4 LC DX Transceiver is a high-performance, hot-pluggable optical module designed for 200GE links over single-mode fiber (SMF) at distances of up to 10km. It combines four 26.5625 GBd PAM4 electrical lanes into four corresponding optical channels, fully compliant with IEEE 200GBASE-LR4 standards. This transceiver delivers superior performance and reliability with an advanced design that incorporates cooled EA-DFB lasers at LAN-WDM 1.3μm wavelengths and four PIN photodetectors with low-power TIAs. The optical signals are multiplexed and demultiplexed onto a single fiber pair through an LC duplex connector, ensuring efficient and reliable data transmission.

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.

PRODUCT PRESENTATION

The PHILISUN QSFP28 100G LAN-WDM 10km LR4 LC DX OUT4 is a 100Gb/s transceiver module designed for optical communication applications, compliant with OTU4 411-9D1F requirements as specified in ITU-T Recommendations G.959.1, G.709, and Supplement 39 (G.sup39). The module converts four 28Gb/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, in accordance with the LAN WDM wavelength grid defined in IEEE 802.3ba. Equipped with high-performance cooled LAN WDM DFB transmitters and high-sensitivity PIN receivers, the module ensures exceptional performance.Designed according to the QSFP+ Multi-Source Agreement (MSA), this transceiver features a compact form factor, robust optical and electrical connections, and a digital diagnostic interface. It is engineered to operate reliably under harsh conditions, including extreme temperatures, high humidity, and EMI interference, making it ideal for demanding environments.

PRODUCT PRESENTATION

The PHILISUN QSFP28 100G CWDM4 10km LC DX Transceiver is a high-performance, 4x25G module designed to optimize reach, bandwidth, density, and cost for high port-count 100G systems and client-side 100G interfaces. Compliant with the 100G 4WDM-10 MSA, based on CWDM4 MSA version 1.1, this transceiver ensures seamless interoperability with other CWDM4 transceivers over distances of up to 10km.

When to choose the 10 km CWDM4 module

This 10 km variant is intended for CWDM4 links that exceed the 2 km class. It uses a duplex LC interface and single-mode fiber. Before deployment, verify host FEC, connector loss and the link-budget limits in the performance tables below.
