FAQ
Q1: How to clear unknown transceiver CLI identification alarms on H3C-compatible 100G QSFP28 LR4 10km Transceiver?
A: Two feasible solutions are available. You can activate the device’s service unsupported-transceiver configuration command, or send the module back to our factory for customized EEPROM firmware re-flashing to permanently eliminate recognition failure prompts on Comware OS.

Q2: Is optical attenuation required for ultra-short 1km and 2km single-mode links deployed with factory-calibrated 100G QSFP28 LR4 10km Transceiver?
A: Judge according to the module’s maximum receiving power threshold. If the transmit optical power exceeds the rated Pin max value within short fiber spans, you have to install 3dB or 5dB fixed optical attenuators to prevent receiver chip damage.

Q3: Why do EML laser integrated 100G QSFP28 LR4 10km Transceiver generate higher operating temperature than short-reach optical transceivers?
A: Unlike low-power SR4 and CWDM4 short-distance modules, our 100G QSFP28 LR4 10km Transceiver adopts EML lasers and built-in MUX/DEMUX wavelength multiplexing components. These core optical structures consume extra power to stabilize 10km long-haul signal transmission, leading to higher surface temperature.

Q4: What extra latency will be introduced after activating RS-FEC function on long-reach 100G QSFP28 LR4 10km Transceiver fiber links?
A: Turning on RS-FEC will add about 100–250 nanoseconds transmission latency. This delay significantly affects high-frequency trading HFT scenarios, while it brings negligible performance impact on regular enterprise data center network traffic.

Q5: Is seamless optical interconnection achievable between standard LAN-WDM 100G QSFP28 LR4 10km Transceiver and 100G 4WDM-10 single-mode modules?
A: Fully compatible. The 100G 4WDM-10 specification is specially developed to realize complete optical interoperability with IEEE-standard 100G QSFP28 LR4 10km Transceiver on all 10km single-mode fiber link deployments.

Q6: What is the maximum hot-plug mating cycle lifespan of gold finger contacts on commercial 100G QSFP28 LR4 10km Transceiver?
A: Standard QSFP28 connector gold fingers of our 100G QSFP28 LR4 10km Transceiver pass industrial durability testing, rated for at least 100 plug/unplug cycles without electrical contact degradation or structural wear.

Q7: What internal laser chips are equipped inside industrial-grade long-distance 100G QSFP28 LR4 10km Transceiver for 10km fiber transmission?
A: All standard HYTOPTODEVICE 100G QSFP28 LR4 10km Transceiver adopt premium EML electro-absorption modulated lasers to guarantee stable long-span signal integrity. Low-cost DML lasers cannot meet the optical performance standards of 10km 100G long-haul links.

Q8: Why do generic aftermarket 100G QSFP28 LR4 10km Transceiver have extended delivery cycles amid global semiconductor supply shortages?
A: LR4 optical modules rely on scarce custom InP indium phosphide laser chips with tight foundry production capacity. Massive chip backlogs prolong lead times for ordinary suppliers, while HYTOPTODEVICE maintains stable in-house laser component stock to shorten order delivery time.

Q9: Does hardware Rx_LOS signal transmission function work normally on WDM1300 100G QSFP28 LR4 10km Transceiver when switch port transmit power cuts off?
A: Yes. Once the switch Tx power shuts down or the fiber link disconnects, our 100G QSFP28 LR4 10km Transceiver will immediately output Rx_LOS hardware pin signals to notify the H3C host switch of optical link loss status.

Q10: Does MSA-compliant 100G QSFP28 LR4 10km Transceiver support remote software-controlled transmit laser disable via switch CLI commands?
A: Fully supported. Our 100G QSFP28 LR4 10km Transceiver strictly follows QSFP28 MSA industry standards, allowing network administrators to remotely turn off internal transmitter lasers through switch command lines for offline fiber link debugging.
