    Allied Telesis Compatible 40GBASE-LR4 CWDM 1271~1331nm 10km QSFP+ Transceiver , Singlemode Fiber LC , DDM Support

    JUHUA's QSFP-SxxLLR4 is a high performance and cost effective QSFP+ LR4 transceiver designed for 40 Gigabit Ethernet (40GbE) applications. The 40GBase-LR4 QSFP+ transceiver comply with QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 specifications. The 40GBase-LR4 QSFP+ transceiver converts 4 inputs channel of 10.3125Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. On the receiver side, the transceiver optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data. The center wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm. The 40GBase-LR4 QSFP+ transceiver contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface.


    The QSFP-40G-LR4-ATE QSFP+ optics is programmed and tested to be compatible with Allied Telesis data center switches, routers, NICs and other optical transport device for 40G Ethernet and high-performance computing networks. It is an ideal equivalent to Allied Telesis AT-QSFPLR QSFP+ optics module at much lower price, which provides a reliable compatible 40G QSFP+ optics solution for system integrator,distributors and end users in data center networking infrastructure.

    Electrostatic Discharge (ESD):


    Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and otherwise handled in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps.

    Test and Operation

    In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements.


    Typical of optical transceivers, this modules receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event might require that the application re-acquire synchronization at the higher layers (for example, via a serializer/deserializer chip).
