100G Transceivers Guide
100G QSFP28 transceivers are high-speed, compact optical transceivers designed for data centers, enterprise networks, and high-performance computing environments. These transceivers support data rates up to 100 Gigabits per second (Gbps) and are commonly used for high-density 100G Ethernet and InfiniBand applications.
Scalable 100G Solutions for Spine-Leaf Architectures
JTOPTICS® 100G transceivers are essential for high-speed, high-density data center connectivity. They enable fast and reliable data transmission between switches, servers, and storage systems in both spine-leaf and core-distribution network architectures. These modules support scalable bandwidth for cloud computing, virtualization, and AI workloads, making them ideal for modern enterprise and hyperscale data centers.
100G QSFP28 SR4 Transceiver
100GBASE-SR4 QSFP28 transceiver is a parallel 100G optical transceiver. It provides increased port density and total system cost savings. This 100G QSFP28 full-duplex optical transceiver offers 4 independent transmit and receive channels, each capable of 25 Gbps operation for an aggregate data rate of 100 Gbps on 100 meters over OM4 MMF. Generally, 100GBASE-SR4 QSFP28 transceiver converts parallel electrical input signals into parallel optical signals by a driven VCSEL array. The transmitter module accepts electrical input signals compatible with CML (common mode logic) levels.
100G QSFP28 PSM4 Transceiver
100GBASE-PSM4 QSFP28 transceiver is a parallel 100G single-mode optical transceiver with an MTP/MPO fiber ribbon connector. It uses 8 fibers (4 transmit and 4 receive), each transmitting at 25 Gbps, resulting in an aggregate data rate of 100 Gbps on 500 meters over SMF. The working principle of 100GBASE-PSM4 QSFP28 transceiver is nearly the same with the 100G QSFP28 SR4 transceiver. The only difference is that PSM4 works over SMF, while SR4 works over OM4 MMF.
100GBASE-CWDM4 QSFP28 Transceiver
100GBASE-CWDM4 QSFP28 transceiver is a full duplex 100G QSFP28 optical transceiver that provides a high-speed link at aggregated data rate of 100 Gbps over 2 km on SMF. The transmitter path converts four lanes of serial electrical data to optical signal. The optical signals from the four lasers are optically multiplexed and coupled to single-mode fiber through an industry standard LC optical connector. The optical signals are engineered to meet the CWDM4 MSA specifications. On the receive side, the four incoming wavelengths are separated by an optical demultiplexer into four separated channels.
100G QSFP28 LR4 Transceiver
100GBASE-LR4 QSFP28 transceiver converts 4 input channels of 25 Gbps electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100G optical transmission. On the receiver side, the module demultiplexes a 100G optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba.
