The 200G QSFP56 optical transceiver module is an upgraded version of the 40G QSFP+ and 100G QSFP28 transceiver modules, which is designed for 200G Ethernet. UnitekFiber's 200G QSFP56 fiber transceiver module is hot-pluggable, and features 4 independent transmitting and receiving optical signal channels with transmission rates up to 53.125Gbps per channel (50G PAM4). The 200G QSFP56 DR4 transceiver module complies with the IEEE 802.3bs 200GBASE-DR4 Ethernet transmission protocol, and InfiniBand HDR transmission protocol. The wavelength of 200G QSFP56 DR4 transceiver module is 1310nm, and the transmission distance could be up to 500 meters. Suitable for short and medium-distance interconnections between data center equipment.
Insert 2*200G QSFP56 optical modules into the corresponding switch ports, and connect the fiber optic transceiver with a single-mode or multi-mode fiber patch cord to achieve a 200G transmission rate. Or connect the 200G QSFP56 optical modules on the one end, and 2*100G on the other end through MPO/MTP fiber optic patch cord to achieve 200G transmission rate.
Using advanced wavelength division multiplexing technology allows the 200G fiber transceiver to use more wavelengths to transmit data, thereby significantly increasing the transmission capacity of the optical fiber. Advanced PAM4 modulation technology improves the signal transmission rate and spectrum utilization of 200G QSFP56 SFP modules. The complex digital signal processing algorithms to optimize signal the transceiver module’s transmission quality and reduce bit error rates, thereby achieving more intelligent signal processing.
200G QSFP56 transceiver modules provide higher transmission rates to meet the extreme bandwidth requirements of data centers and high-performance computing networks. While maintaining high-speed transmission, the energy consumption of 200G transceiver module is reduced. Compared with 50G optical modules and 100G optical modules, 200G QSFP56 modules have a better energy efficiency ratio. And the 200G optical module supports long-distance transmission, adapting to the layout needs of large-scale networks.
Yes, QSFP56 can be inserted into the QSFP-DD port. QSFP-DD has backward compatibility. But OSFP cannot be inserted into QSFP-DD port.
The transmission distance of 200G QSFP56 optical transceiver module can be divided into SR4, DR4, FR4, LR4, ER4, etc.
It depends on the compatibility of the network equipment. Most modern network switches, routers, and equipment support 200G QSFP56 optical transceiver modules.
Compared with NRZ, PAM4 has the advantages including: doubling the density of data, achieving higher resolution using the same oversampling rate, and having the same total noise power spread over a wider frequency so that the noise power in bandwidth goes down. PAM4 clearly offers power, footprint, and cost advantages because of the reduced number of transceivers compared to an identical NRZ solution (1/2 the number of TX/RX).
QSFP56 transceiver specification allows maximum power consumption of <5 Watts.
I have put 200G QSFP56 transceiver modules into service and they work well. I use them in a personal environment rather than a professional one, but I will probably buy more in the near future.
I am very happy with the cables, price and delivery and will probably continue to buy from UnitekFiber. I'm sure I'll be placing another small order in the next few days for some random items we're missing.
The ordering process was great, with a speedy delivery. I am due to have the products installed next week and can follow up with further feedback once tested. So far I have been very impressed.
Currently, I am conducting compatibility testing between the 200G transceiver module and my devices, and the UnitekFiber products seem quite impressive. They have started running, and everything is working well. There are no compatibility or performance issues, and the bandwidth and transmission speed have been tested successfully.
This module meets my expectations and has been running reliably without any issues so far. And The logistics were fast. Highly recommended.
