QSFP ER4 Optical Transceiver 40G 40KM

QSFP ER4 Optical Transceiver 40G 40KM

Short Description:

QSFP ER4 Optical Transceiver is a transceiver module designed for 40km optical communication applications. The design is compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid…

    Description

    QSFP ER4 Optical Transceiver is a transceiver module designed for 40km optical communication applications. The design is compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.

    The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G694.2. It contains a duplex LC connector for the optical interface and a 148-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module.

    The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

    Note:

    1. The supply current includes QSFP+module’s supply current and test board workingcurrent.

    2.. Average launch power, each lane (min) is informative for 40GBase-ER4, not the principal indicator of signal strength.

    3.The receiver shall be able to tolerate , without damage, continuous exposure to anoptical input signal having this average power level

    1. 4. The average receive power , each lane (max) for 40GBASE-ER4 is larger than the40GBASE-LR4 transmitter value to allow compatibility with 40GBASE-LR4 units at shortdistances
    2. 5. Average receive power, each lane (min) is informative and not the principal indicatorof signal strength. A received power below this value cannot be compliant; however, a valueabove this does not ensure compliance
    3. 6. Receiver sensitivity (OMA), each lane (max) is informative
