FAQ for 100G LR4 QSFP28 10km Optical Module

Q1:What is QSFP28 100G LR4 module? A:The 100G QSFP28 LR4 is a hot pluggable optical transceiver module.It utilizes Single-Mode Fiber (SMF) and LAN-WDM technology(wavelength:1295~1310nm) , transmitting distance up to 10km. It is ideal for 100G Ethernet links, Infiniband QDR and DDR interconnects, Data center and Enterprise networking.

Q2:How does the performance compare to the original Juniper module?A:HYTOPTODEVICE 100G module uses top lasers and chipsets that meet or exceed the MSA (Multi-Source Protocol) standard. In actual tests both domestically and internationally, its bandwidth, latency, transmission distance, power consumption, and bit error rate are identical to the original manufacturer's version, while the price is more than 70% cheaper.

Q3:What fiber connector is required for the 100G QSFP28  LR4 module?A:The Juniper QSFP28 100G LR4 10km transceiver uses duplux LC connector with SMF.

Q4:Does this 100G LR4 module support DOM?A:Yes. Yes, it supports Digital Optical Monitoring (DOM), allowing real-time monitoring of optical power,temperature, laser bias current and voltage.

Q5:What does "LR4" stand for in QSFP-100G-LR4-D ?A:In optical communication industry, LR4 stands for "Long Distance 4-Channel". It uses four WDM channels (25Gbps each) to transmit 100G traffic over SMF up to 10 kilometers long.

Q6:What does the "-D" in Juniper QSFP-100G-LR4-D stand for?A:The "-D" designation is typically used by Juniper to differentiate modules optimized for data center platforms or specific high-density port configurations. Our compatible optical modules fully comply with these specific electrical and firmware requirements.use with peace of mind.

Q7:Q: 100G LR4 vs 10G LR: What are the main technical differences? A: The difference is below:

Q8:Is the 100G QSFP28 LR4 backward compatible with lower-speed modules,such as 10G?A: A 100G QSFP28 LR4 module is not natively backward compatible with lower-speed modules. the reasons are the mismatch about form factor,lane configuration and wavelength.

 Q9:How do HYTOPTODEVICE ensure 100G QSFP28 LR4 module compatibility with network switch?A:Ensuring 100% compatibility, optical transceiver modules must be coded to match the switch's requirements. 100G Optical Transceiver Manufacturer China HYTOPTODEVICE was equipped with 100+ branded high-speed switches, ensure they are recognized and running in your device. you can watch compatibility test video before buying.
 
Q10:Is this module hot-swappable on Juniper devices?A:Yes,HYTOPTODEVICE 100G LR4 transceiver are hot-pluggable, hot Pluggable QSFP28 MSA Compliant.you can plug or unplug the 100G optical transceiver on Juniper devices, while the device is powered on without damaging the hardware.

Q11:who makes China best 100g transceiver?A: 100G Optical Transceiver Manufacturer China HYTOPTODEVICE ensures that the QSFP28-100G-LR4 is coded and tested for full compatibility with major switch vendors (such as Cisco, Juniper, Arista, and huawei). They verify the EEPROM settings to ensure "plug-and-play" functionality without port-recognition errors.
