Outstanding Performance The BlueOptics BO04Q27620D BIDI Small Form-Factor Pluggable 28 (SFP28) transceiver with LC Simplex connector from CBO is designed for long-range single-mode 25 Gigabit Ethernet (25GbE) high-speed applications of up to 25.78 Gigabits per second. Versatile Applications The BlueOptics BO04Q27620D BIDI SFP28 transceivers feature a combined receive (Receiver) and transmit (Transmitter) function over a single laser (BOSA) for the transmission of optical signals via single-mode fiber. This is done in accordance with the relevant 25 Gigabit protocol, such as the 25GB Ethernet standard IEEE 802.3by. BlueOptics BO04Q27610D BIDI SFP28 modules are suitable for use in switches, routers, storage systems, and other hardware in the second optical window, with 1270nm and 1330nm.
