Juniper QSFP+ Module - For Data Networking, Optical Network - 1 x LC Duplex 40GBase-BXSR Network - Optical Fiber - Multi-mode - 40 Gigabit Ethernet

The 40-Gbps bidirectional transceiver has a dual transmitter/receiver that allows it to transmit and receive data through a single optical fiber. Each bidirectional transceiver has two LC receptacles that receive and transmit on different optical wavelengths. The wavelength of the input optical signal needs to match the receive wavelength of the pairing transceiver. For example, if transceiver A has a transmit wavelength of 850 nm and a receive wavelength of 900 nm, then the pairing transceiver B should have a matching receive wavelength of 850 nm and a transmit wavelength of 900 nm.
