UnitekFiber's QSFP28 100G-LR4 transceiver module supports transmission distance up to 10km over single-mode fiber with duplex LC connector. Our QSFP28 100G-LR4 fiber transceiver is built to meet or exceed OEM specifications, complies with the IEEE 802.3ba standard. The 100GBASE QSFP28-LR4 optical transceiver features an excellent design with outstanding reliability, air-tightness, and thermal performance. The 100GBASE LR4 fiber transceiver which has 4x25Gbps optical input signals, offers customers a wide variety of high-density and low-power 100 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications.
The 100G QSFP28 transceiver module serves as a crucial component in modern network connectivity by providing fast and reliable data transmission with compatibility with various fiber types and protocols. Its high-bandwidth capacity and versatility make it an indispensable element in modern network designs.
Each QSFP28 fibre transceiver module is quality tested for compatibility in the multi-brand switches environment, which guarantees flawless operations. Such as Cisco, Arista, HP, HUAWEI, Juniper, TP-Link or etc.
UnitekFiber use leading product design, first-class materials and production technology to ensure the first-class quality of 100G QSFP28 optic transceiver, so that your project can be used, installed stably and reliably. All 100G transceiver module will pass through Temperature Impact, Mechanical Impact, EMI Testing and MTBF Testing or more. Qualified through a rigorous process with advanced equipment to ensure you get the high quality and reliable fiber optics module.
Yes, QSFP28 can be inserted into the QSFP port. QSFP has backward compatibility. But QSFP cannot be inserted into QSFP28 port.
It depends on the compatibility of the network equipment. Most modern network switches, routers, and equipment support 100G QSFP28 optical transceiver modules.
QSFP28 transceiver specification allows maximum power consumption of <5 Watts.
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.
The transmission distance of 100G QSFP28 optical transceiver module can be divided into SR4, DR4, FR4, LR4, LR4, etc.
I have put 100G QSFP28 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.
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 100G 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.
