The adapter supports QSFP56/QSFP28/QSFP+ optical modules and copper direct-attach cables. Using a simple adapter or a special direct attached cable it is possible to connect those interfaces together using just one lane instead of four provided by the QSFP/QSFP+/QSFP28/QSFP56 form factor. All QSFP-DD-based transceivers from 40G to 200G are backward compatible with QSFP+. 0, supporting backwards compatibility for v4. The QSW-M7308R-4X comes with four 100GbE QSFP28 and eight 25GbE SFP28 fiber ports, which support DAC or LR/SR Transceivers with the compatible interfaces. The puzzles of transceiver compatibility often focus on optics-to-device or optics-to-optics interoperability. 0 today. 5W, DDM) Laser emitter: Class-one 1310nm (single-mode) 4x25Gb/s 850mm VCSEL-based transmitter; Operating distance: Compliant with IEEE 802. ) The backward compatibility is very critical and advantageous for the end-users and also for the system designers, as it provides flexibility. The QSFP-DD optical transceiver is also forward/backward compatible with QSFP, QSFP28 optical transceiver, AOC/DAC and so on. However, it will be needed to consider the types of transceivers used and data rates when planning or upgrading a network to minimise any bottlenecks which might occur during peak periods. 1. Backwards compatible with QSFP+ cables and transceivers Comprehensive product portfolio Applications By Protocol 50, 100 and 200 Gigabit Ethernet 100 Gbps Infiniband (IB) Enhanced Data Rate (EDR) requirements 128G Fibre Channel 25G/50G Consortium 28G NRZ and 56G PAM-4 DATA AND DEVICES /// QSFP28/56 AND zQSFP+ INTERCONNECTS 6. 100G QSFP28 DAC is a 4-channel parallel passive copper cable that is combining four 28 Gbps SFP channels into one high-density cable. The QSFP-DD connector has the same pinout as the older QSFP connector. QSFP-DD ports can accommodate QSFP-DD, QSFP56, QSFP28 and QSFP+ products. Supports point-to-point 100G Lambda MSA 100 ER1 up to 40km. JH234A, JH235A, JH236A, *721064-B21:10. Backwards compatibility Systems designed with QSFP-DD ports are backwards compatible to support existing QSFP+, QSFP28, and QSFP56 modules. Like the native 40Gb BiDi, the dual-rate 40/100 Gb BiDi transmits bi-directionally on both fibers, using nominal wavelengths of 850nm and 910nm and passive wavelength division multiplexing (WDM) filters at either end isolate Tx and Rx channels. 1016. 34. 1 IOS-XR. Identical mating interface as the QSFP+ connector for backward compatibility: Protects end user's current QSFP+ infrastructure investment 3D-style press-fit pin design: Increased board retention versus typical press pins Drop-in replacement to standard cages: Enables quick and easy implementation without extensive redesignThe Cisco QSFP-100G-SR1. 400G QSFP DD provides more flexibility and scalablibity since it has more lanes (8 or 4 lanes) than. 2028. In brief, the new-gen optical transceiver is backward compatible with the previous version in most situations. Compatible with IEEE 802. FEC on the host platform. SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. The table below describes the FS QSFP28 100G modules. 1. 0 Helpful. 2000. It is one of the industry’s leading multi-lane pluggable form factors used across Ethernet, Fibre Channel and InfiniBand. 1.
