Product Overview

This 100G QSFP28 DR module offers full plug-and-play compatibility with EdgeCore ET7402-DR1.
It uses single-lambda PAM4 architecture. Fewer optical components lower failure risks compared with 4×25G CWDM4 modules.
It delivers 100G links up to 500m over OS2 single-mode fiber. It supports 400G DR4 breakout, allowing gradual 100G to 400G upgrades without full hardware refresh.
DDM/DOM enables real-time parameter monitoring. Low-power design reduces rack thermal load and data center PUE.
Pre-programmed EdgeCore-adapted EEPROM guarantees zero-alarm operation. It meets IEEE and QSFP28 MSA standards, suitable for leaf-spine fabric, core trunks and ToR uplinks.

Usage Guidelines & Best Practices

  • Fiber requirement: Only OS2 single-mode fiber. OM3/OM4 multimode cannot support 1310nm PAM4 and will cause link failure.
  • FEC suggestion: Enable standard FEC on EdgeCore ports to compensate connector and splice loss.
  • Installation: Hot-plug capable. Keep LC end faces clean and maintain specified fiber bend radius.
  • Distance limit: Designed for indoor 500m short reach only. Select FR/LR modules for longer transmission.
  • Environment: Operating range 0°C–70°C. Keep ports dry and dust-free to extend service life.

FAQ

Q1: Which standard specification does 100GBASE-DR transceiver follow?
A1: As a reliable optical transceiver vendor, HYTOPTODEVICE manufactures EdgeCore ET7402-DR1 compatible 100G DR modules that comply with IEEE 802.3cd and 100G Single Lambda DR MSA. We adhere strictly to global industry standards to deliver stable single-wavelength PAM4 transmission over duplex single-mode fiber.

Q2: What is the practical difference between 100G DR, 100G FR1 and 100G LR1 modules?
A2: HYTOPTODEVICE develops targeted 100G optical transceivers for different transmission distances. Our 100G DR is optimized for 500m indoor leaf-spine inter-switch links. FR1 covers 2km and LR1 reaches 10km. DR adopts low-power simplified optics, while FR1 and LR1 use higher-power transmitters to support longer fiber spans.

Q3: What optical chip solution does your 100G DR transceiver adopt?
A3: HYTOPTODEVICE selects mature DML direct modulated laser chips for EdgeCore ET7402-DR1 compatible 100G DR transceivers. Our engineering team balances power consumption, cost and PAM4 signal integrity for short-reach data center scenarios. EML and silicon photonics are not applied in this standard model.

Q4: Can 100GBASE-DR transceiver directly link with existing 100G CWDM4 or PSM4 optical modules?
A4: Direct interoperation cannot be achieved. HYTOPTODEVICE’s 100G DR transmits single-lambda PAM4 over one duplex fiber pair. CWDM4 and PSM4 adopt multi-wavelength parallel structures. Our technical team can provide matched module suggestions to avoid incompatible link failures.

Q5: What temperature range does your 100G DR module support? Can it run at industrial -40°C to 85°C?
A5: HYTOPTODEVICE’s standard EdgeCore compatible 100G DR is commercial grade, rated 0°C to 70°C. We accept customized industrial-temperature optical modules on demand. Standard stock cannot support -40°C to 85°C industrial deployment.

Q6: Why must switch-side FEC be enabled for stable 100G DR links?
A6: HYTOPTODEVICE’s R&D team designs 100G DR with tight optical power budget for 500m maximum reach. Host-side FEC offsets connector loss, splice loss and minor signal distortion to maintain qualified BER. Every unit passes pre-shipment testing with correct FEC configuration.

Q7: What risks appear if I disable FEC on the switch port for 100G DR?
A7: Disabling FEC greatly reduces available link margin. Users may face unstable negotiation, rising bit errors, frequent link flapping and random packet loss, especially near the 500m limit. HYTOPTODEVICE engineers offer free port configuration guidance during deployment.

Q8: Can I deploy 100G DR transceiver on fiber runs longer than 500m such as 1km or 2km?
A8: HYTOPTODEVICE technical team does not recommend overlength deployment. 500m is the engineered rated distance. Longer fiber triggers severe attenuation and dispersion. We supply 100G FR1 modules for 1km–2km interconnection demands.

Q9: What chromatic dispersion tolerance does your 100GBASE-DR transceiver have?
A9: HYTOPTODEVICE’s 100G DR is optimized for short-reach data center links with around 4 ps/nm dispersion tolerance. It cannot meet dispersion requirements for FR1 and LR1 long-distance transmission. Our sales team can recommend suitable models based on your actual fiber length.

Q10: Is 100G DR transceiver more expensive than 100G CWDM4 when purchasing in bulk?
A10: Bulk pricing varies by order quantity. HYTOPTODEVICE’s 100G DR uses fewer optical components and simple duplex cabling. For leaf-spine and 400G migration architectures, most of our customers gain lower total TCO compared with CWDM4 alternatives.

Q11: What core value does 100G DR bring during data center upgrades to 400G and 800G networks?
A11: HYTOPTODEVICE’s 100G DR supports 400G DR4 breakout. It enables customers to connect new 400G switch ports with legacy 100G equipment, reuse existing fiber infrastructure and carry out phased upgrades. We provide full pre-sales technical consultation for data center migration projects.
