QSFP28, QSFP56 transceivers have a 38pin electrical interface which connects to the host device. In total, 31 companies came together in support of the QSFP112 MSA to address the industry need for high-speed, high-density networking. 0, supporting backwards compatibility for v3. If the QSFP28 optics support 25G. Backwards compatible with QSFP. Supported by PAM4 modulation, QSFP DD is a more cost-effective solution for 400G DCI with ultra-low power consumption. Enhanced cage products for faster assembly and increased EMI performance. It provides 4 high-speed differential signal channels, supporting rates from 25 Gbps to 40 Gbps. This QSA is backwards compatible to 10G SFP+ products and accepts a SFP-based device inserted in the adapter end. Conclusion. Like the single-rate 40G BiDi, it lets you seamlessly upgrade short reach links from 10G without having to replace duplex LC-connectorized MMF fiber infrastructure originally meant for 10G SR. 1. 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. It has a similar size compared to the QSFP transceiver (QSFP+/QSFP28/QSFP56) but it has eight data lanes instead of four. Some QSFP-DD modules have the capability to interface to multiple 100G modules when operated in breakout mode, providing higher port density for 100G interfaces, and easing the migration to 400G platforms Data rate. 33G CPRI and 25. 4 Tbps: Ports: 32x 100G. Oct 29, 2000. ) and provide flexibility for end-users and system designers. Ports: 1 OSFP port. QSFP28-DD ports are backwards compatible and support QSFP28 and QSFP+ Optics and cables. SFP+ / SFP28 / SFP backwards compatibility. 3dB Yes Datasheet SO-QSFP28-SWDM4 100GE 150m 850/880/910/940nm MM 2x LC 100G SWDM4 1. Each QSFP-DD port can operate at 400, 100, 50, 40, and 25 Gbps. In brief, the new-gen optical transceiver is backward compatible with the previous version in most situations. Product Collection Intel® Silicon Photonics Pluggable Optical Transceivers; Marketing Status Launched; Launch Date Q3'17; Additional Features • Compliant with CWDM4 MSA optical interface specification, with reach up to 500 m, 2 km, or 10 km depending on version• Compact QSFP28 form factor for high faceplate density in networking equipment •. In the 100G optics market, QSFP28. The common 100G QSFP28 transceivers include 100G SR4, LR4, CWDM4, and PSM4. The technology was first defined by the IEEE 802. This firmware supports the following protocols: Ethernet - 1GbE, 10GbE, 25GbE, 40GbE, 50GbE 1, 100GbE 1, 200GbE 2. You can rest assured that your Fortinet transceivers have been tested for compatibility on Fortinet products, taking the guesswork out of selecting transceivers for your environment. 0, v3. QSFP28 is designed for 100G Ethernet and can support data rates up to 100 Gbps over four channels, each channel support 25Gbit/s. The cage and connector design provides backwards compatibility to QSFP28 modules which can be inserted into a QSFP-DD port and connected to 4 of the 8 electrical channels. Is SFP28 compatible with SFP+? Yes, the SFP28 port does take the SFP+ port but not vice versa. 1 IOS-XR. GIGALIGHT also provides Active Optical Cables (AOCs) that can replace short-distance (e. The 100G QSFP28 module solution provides high-performance 100GbE connectivity for data centres, enterprise core & distribution layers, computing networks and service provider applications. But QSFP-DD as it is double density, has a double count of electrical pins – 76. In many instances standard SFP+ optics can be readily inserted, recognized, and utilized in theThe puzzles of transceiver compatibility often focus on optics-to-device or optics-to-optics interoperability. 0, supporting backwards compatibility for. SR4. #4. The Mellanox data sheet shows multi-speed compatibility. Additionally, it provides a unique. approach allowing backwards compatibility with 100G modules (4x interface) Integrated heatsink Backwards compatible with 100G QSFP28. Available with in-house tested full-feature compatibility in Arista, Cisco, Juniper, and more. This basically means that systems (host devices) which are designed with QSFP-DD port are backward compatible with QSFP56 and QSFP28 form factor transceivers. The difference in data rate also accounts for a difference in transmission distance—SFP typically has a longer transmission distance. 32 fixed 400-Gigabit Ethernet QSFP-DD ports with backward compatibility for QSFP56, QSFP28, and QSFP+. The 25GbE SFP28 interface is also backwards compatible with. QSFP28 is suitable for applications with 100G network requirements. Systems designed with QSFP112 cage and connector will be backwards compatible with existing QSFP28/56 Module, and systems designed for QSFP112 module will be compatible with existing QSFP-DD800 cage and connector. 3ba-2010 standard. com Backward compatibility: allowing the QSFP-DD to support existing QSFP modules (such as QSFP+, QSFP28, QSFP56, etc. With the trends of enterprise server access. Referring to the table on pages 2-4, the switches that may have compatibility issues with Panduit. The common 100G QSFP28 transceivers include 100G. 1 1G SFP. migration, and backwards compatibility allows for a staged approach to higher-speed networks. them backward compatible with existing SFP+ I/O ports. This is due to the fact that SFP28 can reach up to a transmission rate of 28Gbps, which gives it its name: SFP28. A leading networking company discovered that their new 100 Gbps switch. DAC-Q28DD-2Q28-100G-xM. ASIC design: various interface rates are supported and the modules are completely backward compatible with QSFP28 and QSFP+ modules, lowering port and equipment deployment expenses. While QSFP+, QSFP28, and QSFP56 can achieve 40G, 100G, and 200G data rates, the lower lane count means that even with PAM4 modulation 400G data rates are not possible. Whereas, each channel of QSFP28 optics come with 25 GB/s. These are the release notes for the NVIDIA® ConnectX®-6 Lx adapters firmware Rev 26. Backward compatibility: the QSFP-DD may support current QSFP modules (QSFP56, QSFP+, QSFP28, and others), giving end-users and system designers more options.
