Applications

100GBASE-SR4 Ethernet links

Data center

ESD

This transceiver is specified as ESD threshold 1kV for high speed data pins and 2kV for all other electrical input pins, tested per MIL-STD-883, Method 3015.4 /JESD22-A114-A (HBM). However, normal ESD precautions are still required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment.

​​Q1: How does the SR4 differ from "LR4" or "ER4" models?​​
​​A1:​​ Key distinctions are ​​distance and fiber type​​:
​​SR4​​: Short reach (≤100m), uses ​​multimode fiber​​, cost-effective for intra-data center links.
​​LR4/ER4​​: Long reach (10km–40km), uses ​​single-mode fiber​​, suitable for inter-building or metro connections.

Q2: Is this QSFP28 100G SR4 compatible with Cisco/Huawei/Juniper switches?​​

​​A2:​​ Yes. Plug-and-play on any switch supporting ​​QSFP28 form factor​​ and ​​100GBASE-SR4 standards​​ (standard for major brands).

​​Q3: What are key usage precautions?​​

​​A3:​​ Critical notes:

​​Clean fiber ports regularly​​: Dust causes signal loss. Use MPO-specific cleaning tools.

​​Avoid tight fiber bends​​: Minimum bend radius must be maintained to prevent fiber damage.
