The FRM220-40G-1Q4S is a 40G QSFP⁺ to 4x 10G SFP⁺ transponder that provides media conversion and distance extension for 40G over 10G links. The FRM220-40G-1Q4S meets the growing need for more bandwidth for data centers and enterprises. The emergence of high-end servers and Ethernet switches with 40G Ethernet interfaces increases the need for media conversion (multi-mode to single-mode) and link range extension. The FRM220-40G-1Q4S is a two slot wide hot-swappable card with one QSFP⁺ slot for QSFP⁺ 40G transceiver and four SFP⁺ slots for SFP⁺ 10G transceivers. The installation and setup is simple plug and play. The FRM220-40G-1Q4S can be inserted into any powered FRM220-CH20 chassis with QSFP⁺ and SFP⁺ transceivers required for the application. For standalone unit, please use 2-slot chassis with cooling fans such as FRM220-CH02M-AC at $105 each.
