Usage Guidelines & Best Practices

1. Fiber Type Requirement: This 100G DR module only works with OS2 single-mode fiber. OM3/OM4 multimode fiber cannot support 1310nm PAM4 signals and causes link failure.
2. FEC Configuration: Enable standard FEC on Ruijie Networks ports. It compensates for connector and splicing loss. It ensures stable transmission at the 500m maximum distance limit.
3. Installation Tips: Hot-plug capable. Keep LC end faces clean and scratch-free. Maintain standard fiber bend radius to avoid extra optical attenuation.
4. Distance Limit: Designed for 500m indoor short-reach scenarios only. Choose 100G FR/LR modules for longer-distance transmission.
5. Operating Environment: Working temperature: 0°C–70°C. Keep ports dry and dust-free to extend module service life.

FAQ

Q1: Which standard specification does 100GBASE-DR transceiver follow?
A1: As a trusted optical transceiver manufacturer, HYTOPTODEVICE produces Ruijie 100G-QSFP-DR1-SM1310 compatible 100G DR modules that follow IEEE 802.3cd and 100G Single Lambda DR MSA. We follow global standards strictly to offer stable single-wavelength PAM4 transmission over duplex single-mode fiber.

Q2: What practical differences exist between 100G DR, 100G FR1 and 100G LR1 modules?
A2: HYTOPTODEVICE develops targeted 100G transceivers for different distances. Our 100G DR is built for 500m indoor leaf-spine inter-switch links. FR1 covers 2km and LR1 reaches 10km. DR uses low-power simplified optics, while FR1 and LR1 adopt higher-power transmitters for longer fiber spans.

Q3: What optical chip technology does your 100G DR transceiver use?
A3: HYTOPTODEVICE selects mature DML direct modulated laser chips for 100G-QSFP-DR1-SM1310 compatible 100G DR units. Our engineering team balances power consumption, cost and PAM4 signal quality for short-reach data center environments. EML and silicon photonics are not used in this standard model.

Q4: Can 100GBASE-DR transceiver connect directly with legacy 100G CWDM4 or PSM4 modules?
A4: Direct interoperation cannot work. HYTOPTODEVICE’s 100G DR transmits single-lambda PAM4 over one duplex fiber pair. CWDM4 and PSM4 use multi-wavelength parallel structures. Our technical team provides matched module suggestions to avoid incompatible link faults.

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

Q6: Why must FEC be enabled on Ruijie ports for stable 100G DR links?
A6: HYTOPTODEVICE R&D designs 100G DR with tight optical budget for 500m maximum reach. Host-side FEC offsets connector loss, splice loss and minor signal distortion to maintain acceptable BER. Every unit passes pre-shipment testing under correct FEC settings.

Q7: What problems occur if FEC is disabled on the switch port for 100G DR?
A7: Disabling FEC sharply reduces link margin. Users may see 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 use 100G DR on fiber runs longer than 500m such as 1km or 2km?
A8: HYTOPTODEVICE technical team does not recommend overlength usage. 500m is the engineered rated distance. Longer fiber creates 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 recommends proper models based on your actual fiber length.

Q10: Is 100G DR more expensive than 100G CWDM4 when ordered in bulk?
A10: Bulk pricing changes with order quantity. HYTOPTODEVICE’s 100G DR uses fewer optical components and simple duplex cabling. For leaf-spine and 400G migration networks, most customers achieve lower total TCO compared with CWDM4 solutions.

Q11: What core value does 100G DR provide when upgrading data centers to 400G and 800G?
A11: HYTOPTODEVICE’s 100G DR supports 400G DR4 breakout. It allows customers to connect new 400G switch ports with existing 100G equipment, reuse current fiber infrastructure and complete phased upgrades. We provide full pre-sales technical consultation for data center migration projects。
