Quick StartD ESCRIPTIONThe QSFP+ 4x10GBASE-LR4 MPO 10 km (QSFP+ LR4) trans-ceiver is designed for use in 40 Gbps links over single mode fiber.The QSFP+ LR4 integrates four independent transmit and receivechannels. Each channel operates at 10.3125 Gbps. The modulecan operate at 40 Gbps up to 10 km using 9/124 μm single modeoptical fiber (SMF). The QSFP+ LR4 is complaint with QSFP+MSA and IEEE 802.3ba 40GBase-LR4.The QSFP+ LR4 has anMPO (MTP) connector and requires an optical fiber ribbon cablewith MPO (MTP) connectors.INSTALLATIONTo install the QSFP+ LR4 into an applicable module, complete thefollowing steps:1. Inspect the QSFP+ LR4. If damaged, file a claim with thecarrier and then contact ADTRAN Customer Service.2. Do not remove the protective end cap from the QSFP untilthe fiber optic cable is ready to be connected.3. Insert the QSFP+ LR4 into the QSFP cage on the module.Ensure the manufacturer’s label on the QSFP is facingupward for correct installation.4. Slide the QSFP+ LR4 all the way into the receptacle untilthere is an audible “click.”f CAUTION!Due to compliance certification requirements, use only QSFPssupplied by ADTRAN. ADTRAN cannot certify system integritywith other QSFPs.w NOTICEThe loop on the QSFP is used to remove the QSFP from the cageon the circuit card.S PECIFICATIONSGeneral■ Module type: QSFP+■ Fiber/Copper: Fiber■ Lanes/Channels: 4 Transmit and 4 Receive■ Signal data rate: Up to 10.3 Gbps per channel■ Optical Connector: MPO/MTP■ Applications: 40GBASE-LR4 Ethernet, Data Center■ Distance: 10 km over single-mode fiberOptical■ Transmitter♦ Laser Diode Type: DFB Array (4 parallel channels)♦ Tx Wavelengths: 1310 nm (each channel)♦ Tx Output Optical Power: –6.0 to +1.5 dBm at each lane♦ Extinction Ratio: 3.5 dB■ Receiver♦ Rx Type: PIN Array♦ Rx Wavelengths: 1310 nm (each channel)♦ Receive Overload: +2.3 dBm at each lane♦ Receive Sensitivity: –12.6 dBm at each laneEnvironmental■ Controlled Protected Equipment (Inside)♦ Operational temperature range: –5°C to +55°C♦ Storage temperature range: –40°C to +85°C♦ Relative humidity 5 to 85%, non-condensingADTRAN Pluggable OpticsQSFP+QSFP+ 4x10GBASE-LR4 MPO 10 kmJuly 201861445502F4C-13AP/N: 1445502F4C
