Product Overview

This 100G QSFP28 FR1 module delivers plug-and-play compatibility with original Huawei QSFP-100G-FR1 transceivers, acting as a reliable, cost-effective drop-in replacement for Huawei CloudEngine data center platforms.
It adopts industry-standard single-lambda PAM4 modulation and built-in KP4 FEC error correction, supporting stable 100G Ethernet transmission up to 2km over OS2 single-mode fiber. It converts 4×25G NRZ electrical signals into 100G PAM4 optical signals, maintaining signal integrity and low-error transmission for medium-reach Huawei networking.
Fully compliant with IEEE 802.3cd, QSFP28 MSA and 100G Lambda MSA standards, the module supports real-time DDM/DOM digital diagnostics. Pre-flashed Huawei-adapted EEPROM guarantees zero-alarm hot-plug operation, ideal for leaf-spine interconnections, core aggregation trunks, and phased 100G-to-400G FR4 breakout migration.

Usage Guidelines & Best Practices

  • Fiber Requirement: Only compatible with OS2 single-mode fiber; OM3/OM4 multimode fiber cannot support 1310nm PAM4 transmission and will cause link failure.
  • FEC Configuration: Enable standard port FEC on Huawei switches to maximize 2km link margin and ensure ultra-low BER transmission.
  • Installation Specification: Support hot-plug deployment; keep LC fiber end faces clean and maintain standard fiber bend radius to avoid signal loss.
  • Distance Limit: Rated for 2km OS2 SMF transmission; excessive splicing, dirty connectors or over-bending will reduce actual transmission distance.
  • Operating Environment: Commercial temperature range 0°C–70°C; keep port ends dry and dust-free to extend service life.

FAQ

Q1: Which industry standards does 100G FR1 comply with?
A1: HYTOPTODEVICE 100G FR1 transceivers strictly comply with IEEE 802.3cd, IEEE 802.3cu 100GBASE-FR1, 100G Lambda MSA, QSFP28 MSA mechanical and electrical specs, plus RoHS certification. All optical parameters, modulation and hot-swap rules follow universal industry norms, ensuring stable operation on Huawei and multi-vendor networks.

Q2: What are the electrical and optical lane rates of 100G FR1?
A2: Electrically, 100G FR1 uses four 25.78125 Gbps NRZ electrical lanes. The onboard DSP aggregates these lanes and converts them into one optical lane operating at 53.125 GBd PAM4, delivering total effective throughput of 103.125 Gbps to meet standard 100G Ethernet requirements.

Q3: What laser technology is used in 100G FR1?
A3: HYTOPTODEVICE 100G FR1 modules use 1310nm EML (Electro-absorption Modulated Laser) technology. EML provides higher modulation bandwidth, lower TDECQ distortion and better linearity than conventional DFB lasers, supporting high-speed 53.125 GBd PAM4 and stable low-noise output for 2km single-mode links.

Q4: Can 100G FR1 directly interoperate with a 100G DR (500m) module?
A4: Yes. 100G FR1 and 100G DR1 share the same 1310nm wavelength, single-lambda PAM4 modulation, 53.125 GBd baud rate and KP4 FEC. Only the link budget differs: FR1 has higher margin for 2km, while DR1 targets 500m. Mixed interconnection runs without negotiation failures or packet loss.

Q5: What hidden issues can occur in multi-vendor switch interconnects using 100G FR1?
A5: Common risks include mismatched KP4 FEC auto/forced modes causing flapping, vendor EEPROM locks triggering third-party alarms, unequal DSP equalization algorithms leading to jitter, and minor optical power deviations causing silent packet loss over time. HYTOPTODEVICE modules pass multi-brand real-machine calibration to reduce these risks.

Q6: Does 100G FR1 support Industrial Temperature (-40°C to 85°C)?
A6: Standard Huawei QSFP-100G-FR1 compatible modules support commercial temperature 0°C to 70°C for indoor data centers. Industrial temperature (-40°C to 85°C) versions are available upon request. Standard commercial units may suffer unstable optical power, rising BER or link down in extreme environments.

Q7: What are the airflow and cooling requirements when fully populating switches with 100G FR1?
A7: Full-port deployment requires consistent front-to-back airflow. While each module consumes ≤4.0W, cumulative heat builds under dense loading. Keep vents clear, maintain normal fan speed and avoid tightly stacked racks without gaps. Poor airflow raises module temperature, reduces link margin and accelerates aging.

Q8: What happens if the module operates at excessively high temperatures?
A8: Sustained overheating drifts EML laser power, increases optical attenuation and worsens PAM4 distortion, raising BER and triggering intermittent packet loss. Severe cases produce DDM temperature alarms, link flapping or automatic link
down. Long-term thermal stress permanently shortens laser life.

Q9: What is the link budget for 100G FR1? Is it sufficient for 2km?
A9: Standard 100G FR1 link budget provides adequate margin for 2km OS2 single-mode fiber. The 1310nm low-loss window and optimized EML output cover fiber attenuation, splice loss and connector insertion loss while maintaining stable receive power and low BER, with usable redundancy at the rated distance.

Q10: Can 100G FR1 be used for distances beyond 2km (e.g., 2.5km or 3km)?
A10: Not recommended. Temporary link-up may occur, but optical margin becomes insufficient. Extra loss elevates PAM4 error rates and packet loss, and persistent over-distance operation triggers low optical power DDM alarms. For 2–10km links, 100G LR1 is the proper standard solution.

Q11: Why are fiber end-face cleanliness requirements particularly strict for 100G FR1?
A11: 100G FR1 uses sensitive PAM4 modulation, which is far more vulnerable to interference than NRZ. Dust, scratches and oil on end faces cause uneven transmission, reflection and sudden attenuation, distorting PAM4 waveforms, increasing TDECQ and raising error counts. Clean end faces are mandatory for stable 2km high-speed operation.
