100GBASE SR4

The QSFP28 100GBASE-SR4 Transceiver is a high-performance, short-reach optical module designed for 100 Gigabit Ethernet applications in data centers, cloud computing, and high-performance computing environments. Compliant with IEEE 802.3bm and QSFP28 MSA standards, this transceiver utilizes four independent 25G lanes transmitting over 850nm multi mode fiber using a parallel MPO-12 connector, enabling reliable connectivity up to 70 meters (OM3) or 100 meters (OM4). The compact QSFP28 form factor provides high port density for 100G switches and servers, making it ideal for top-of-rack and leaf-spine architectures. With low power consumption and digital diagnostics monitoring capabilities, the 100GBASE-SR4 delivers the performance and reliability required for high-density 100G deployments.

Product Selling Points

 

1. 100G QSFP28 SR4 – Built for Short-Reach Intra-Data Center Links
This QSFP28 transceiver delivers 103.125 Gbps (4 × 25.78 Gbps) over multimode fiber, targeting 100G SR4 Ethernet applications. A perfect fit for top-of-rack switches, GPU clusters, and high-density server interconnects inside modern data centers.

2. 850nm VCSEL Engine Optimized for OM3/OM4 Fiber
Equipped with an 850nm VCSEL array, it pairs seamlessly with OM3 or OM4 multimode fiber. With an optical budget of 2.5dB, the link stays stable and reliable - no signal surprises under real-world conditions.

3. Sub-2.5W Power Profile Cuts Heat and Operating Costs
Typical power draw sits below 2.5W, making this module a strong candidate for large-scale, power-sensitive deployments. Lower heat output means less cooling strain and a smaller energy bill for your data center.

4. Full DDM Telemetry + Programmable EEPROM in a Shielded Housing
Digital Diagnostics Monitoring (DDM) gives you real-time visibility into temperature, voltage, bias, TX and RX power. The zinc-alloy housing with EMI shielding keeps noise out, while the programmable EEPROM stores vendor and serial data. ROHS compliant throughout.

Star Reviews From Customers

 

1.Mike, data center engineer in Virginia
"These SR4 modules are workhorses in our 100G spine-leaf network. The MPO connectors make cabling clean and simple. 100m reach on OM4 covers our row-to-row distances. Plug and play with Arista switches. Good quality, consistent across orders."


2.Carlos, cloud ops in Texas
"Hyper scale deployment needed 2000+ 100G links. These SR4 modules were the choice. Consistent optical power across batches. Lower failure rate than other brands we tried. Would recommend."


3.Tom, network installer in Chicago
"Data center build used these for spine-leaf connectivity. The MPO connectors click in solid, good insertion loss. Work with Juniper switches. Good value for the money."


4.Wei, optical module manufacturer in Shenzhen
"We supply these 100G SR4 modules to data center clients. Full testing at 103.125GBPS ensures performance. Quality control includes optical power, BER, and DDM calibration. Good yields, consistent quality."


5.Alex, HPC engineer in Oregon
"AI training cluster needed high-bandwidth optical links. These SR4 modules deliver. The 100m reach covers our rack spacing. Digital diagnostics help monitor link health. No errors in production."
