10KM 40G QSFP+ Optical Tranceiver Module
The QSFP+ transceiver modules are designed for use in 40 Gigabit per second links over multimode fiber. They are compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4.The optical transmitter portion of the transceiver incorporates a 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) array, a 4-channel input buffer and laser driver, control and bias blocks. The optical receiver portion of the transceiver incorporates a 4-channel PIN photodiode array, a 4-channel TIA array, a 4 channel output buffer, control blocks.
Features Compliant to the IEEE 802.3ba(40GBASE-LR4) Compliant to the QSFP+ MSA SFF-8436 Specification Up to 10km over SMF DFB and PIN monitor photodiodes array for transmitter section PIN detectors and TIAs array for receiver section Four 10Gbps CWDM channels in the 1300nm band I2C interface with integrated Digital Diagnostic Monitoring Utilizes two standard LC optical connector Operating Case Temperature: -10°C ~+70°C
