UnitekFiber’s OSFP56-200G SR4 transceiver module is designed for use in 200-BASE Gigabit Ethernet links up to 100m throughput over multi-mode MTP/MPO fiber patch cord. The wavelength of OSFP56-200G SR4 fiber transceiver module is 850nm. The optical module has 4 independent electrical input/output channels operating up to 53.125Gbps per channel. The 200G OSFP56 fiber transceiver can transmit up to 70m on OM3 fiber patch cord or 100m on OM4 fiber patch cord with FEC. This high quality of 200G SR4 transceiver module are suitable for short-distance interconnections between data center equipment, high performance computing networks, enterprise core and distribution layer applications.
200G QSFP56 optical 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 fiber optic modules and 100G optical modules, 200G QSFP56 optical modules have a better energy efficiency ratio. And the 200G-QSFP56-SR4 optical module suitable for short-distance transmission, which is the most cost-effective transceiver module option when the transmission distance within 100 meters.
For large-scale data centers, high-density and high-bandwidth are the key requirements. The 200G QSFP56 SR4 fiber optical transceiver meet the requirements of large-scale data transmission in data centers by supporting 200G transmission rate, and 100 meters transmission distance are also suitable for short-distance connection within data centers.
UnitekFiber’s QSFP56-200G-SR4 optical transceiver uses a unique chip to reduce power consumption while utilizing the InfiniBand protocol to minimize network latency for short-haul 200G applications up to 100m. The bandwidth and latency test results in HDR network environment fully meet the requirements of low latency and high bandwidth for HPC network.
The transmission distance of 200G QSFP56 optical transceiver module can be divided into SR4, DR4, FR4, LR4, ER4, etc.
Yes, QSFP56 can be inserted into the QSFP56 port. QSFP56 has backward compatibility. But OSFP cannot be inserted into QSFP56 port.
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.
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 200G transceiver module, 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.
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 transceiver module meets my expectations and has been running reliably without any issues so far. And The logistics were fast. Highly recommended.
