On Feb. 29, the Legrand brand Approved Networks announced the release of its new O-band receiver for high-speed data transmission for distances up to 25km.

The company reports that its new QSFP28 O-band transceiver provides a cost-effective way to upgrade bandwidth to 100G and, when paired with Approved’s 16 channel DWDM mux/demux, requires no power outside of the switch and eliminates the need for additional components like amplifiers.

Approved networks senior product design engineer Larry Legg said in a press release, “O-band bridges the cost gap between Coherent and active systems and short reach optics for 100G. By utilizing passive components and PAM4 technology, this solution is well-suited for distances shorter than 25km between any QSFP28-capable switch and allows for potential growth up to 1.6TB/s.”
