FAQ for 100G LR4 QSFP28 10km Optical Module

Q1:What is QSFP28-100G-LR4? 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:What is the maximum transmission distance of the  QSFP28 100G LR4 transceiver?A:HYTOPTODEVICE QSFP28 100G LR4 module supports the maxium transmitting distance of up to 10km.

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

Q4:Does this 100G 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?A:In optical communication, LR4 stands for "Long Distance 4-Channel". It uses four WDM channels (25Gbps each) to transmit 100G traffic over a single-mode fiber up to 10 kilometers long.

Q6:Where to buy 100G QSFP28 LR4 optical transceiver?A:There are many factories that produce and sell 100G  fiber optical modules, but 100G optical transceiver manufacturer china HYTOPTODEVICE is the excellent provider: a source factory, reliable high-performance, 100% compatibility, fast delivery, and quick response.

Q7:Q: 100G QSFP28 LR4 vs 10G SFP+ LR,What is the differenct? A: The difference as follow:

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 100GBASE-LR4 transceiver hot-swappable?A:Yes,HYTOPTODEVICE fiber transceiver modules are hot-pluggable, hot Pluggable QSFP28 MSA Compliant.you can plug or unplug the optical transceiver, 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.
