GLOBALfiber Q40G-eSR4 is an extended-reach 40G QSFP+ transceiver for multimode fiber links up to 300 m. Four independent optical transmit and receive channels at 850 nm connect through an MPO/MTP interface for rack-to-rack and data center interconnects.
Available coding and compatibility
Available coding options: Alcatel, Arista, Ciena, Cisco, Dell, Extreme, Fortinet, Generic, HP, Huawei, IBM, Infinera, Intel, NVIDIA-Mellanox(ETH).
Provide the equipment model, port configuration and software version so we can check support. Coding availability does not confirm compatibility with every equipment model. For other coding requirements, contact salg@globalfiber.no. Ethernet coding does not by itself confirm InfiniBand support.
