It carries 400GE over a single duplex multimode fibre pair with an LC UPC connector, making it suited to short-reach data centre links, including AI and cloud fabrics, where existing duplex LC MMF cabling is already in place.\u003c\/p\u003e\u003cp\u003eIt reaches 50 m on OM3, 70 m on OM4 and 100 m on OM5 fibre, using four 100Gbps bidirectional wavelengths per fibre at 850, 880, 910 and 940 nm. The electrical interface is 400GAUI-8, 8 x 26.5625GBd PAM4, with a line rate of 425 Gbps. Forward error correction is performed on the host platform, so the host port must support it. Because it reuses the same duplex LC connectors and MMF infrastructure as 40G and 100G BiDi optics, upgrading to 400G does not require fibre retermination or MPO conversion.\u003c\/p\u003e\u003cp\u003eThe module is designed for Cisco QSFP-DD 400G ports and is backward compatible with QSFP-100G-SR1.2 at 100G speed. Confirm host platform and software release support against the Cisco transceiver compatibility matrix before deployment.\u003c\/p\u003e\u003cp\u003eEnquire with XS Network Tech for new or used pricing and availability.\u003c\/p\u003e","brand":"Cisco","offers":[{"title":"Default Title","offer_id":67729106829482,"sku":"QDD-400G-BD","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/9181\/8922\/files\/datasheet-c78-743172_7.png?v=1792714312","url":"https:\/\/www.xsnet.com.au\/products\/cisco-qdd-400g-bd-400g-qsfp-dd-bidi-transceiver-mmf-100m-om5-lc","provider":"XS Network Tech","version":"1.0","type":"link"}
