Transition Networks has announced the release of a new family of 100G QSFP28* optical transceivers (TN-QSFP-100G Series) designed for data intensive 100 Gbps Ethernet networks. As data center operators upgrade access switch links to 10 Gigabit Ethernet (10 GbE), they need 100 GbE aggregation links to core switches. QSFP28 optical interfaces are the most compact 100 GbE pluggable interfaces in the market, resulting in higher port-density switches that are ideal for this application.
The Transition Networks TN-QSFP-100G Series of 100G optical transceivers are designed to install in any QSFP28 switch port. The TN-QSFP-100G-LR4 supports the 100GBase-LR4 standard for single mode fiber and features standard duplex LC connectors. The transceiver has a transmission distance of up to 10 km over structured single mode fiber. The transceiver converts four input channels of 25 Gbps data to four channels of LAN WDM optical signals and then multiplexes them into a single channel for 100 Gbps optical transmission. The receiver side device de-multiplexes the WDM input into 4 optical signals. The TN-QSFP-100G-CWDM4 has a transmission distance of up to 2 km over single mode fiber.
