    ◊ Utilizes a standard LC duplex fiber cable allowing reuse of existing cable infrastructure

    Applications:

    ◊ 40 Gigabit Ethernet interconnects

    ◊ Datacom/Telecom switch & router connections

    ◊ Data aggregation and backplane applications

    ◊ Proprietary protocol and density applications

    Description:

    It is a Four-Channel,Pluggable, LC Duplex, Fiber-Optic QSFP+ Transceiver for 40 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range duplex data communication and interconnect applications. It integrates four electrical data lanes in each direction into transmission over a single LC duplex fiber optic cable. Each electrical lane operates at 10.3125 Gbps and conforms to the 40GE XLPPI interface.

    The transceiver internally multiplexes an XLPPI 4x10G interface into two 20Gb/s electrical channels, transmitting and receiving each optically over one simplex LC fiber using bi-directional optics. This results in an aggregate bandwidth of 40Gbps into a duplex LC cable. This allows reuse of the installed LC duplex cabling infrastructure for 40GbE application. Link distances up to 100 m using OM3 and 150m using OM4 optical fiber are supported. These modules are de- signed to operate over multimode fiber systems using a nominal wavelength of 850nm on one end and 900nm on the other end. The electrical interface uses a 38 contact QSFP+ type edge connector. The optical interface uses a conventional LC duplex connector.

    1. Power on is defined as the instant when supply voltages reach and remain at or above the minimum specified value.

    2. Fully functional is defined as IntL asserted due to data not ready bit, bit 0 byte 2 de-asserted.

    3. Measured from falling clock edge after stop bit of read transaction.

    4. Measured from falling clock edge after stop bit of write transaction.

     Notes:

    1. GND is the symbol for single and supply(power) common for QSFP modules, All are common within the QSFP module and all module voltages are referenced to this potential otherwise noted. Connect these directly to the host board signal common ground plane. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
    2. VccRx, Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown below. VccRx, Vcc1 and VccTx may be internally connected within the QSFP transceiver module in any combination. The connector pins are each rated for maximum current of 500mA.
