Usage Guidelines & Best Practices

  • Fiber Matching: This 2km CWDM4 module requires OS2 single-mode fiber. Multimode fiber leads to heavy attenuation and unreliable links.
  • Port Configuration: Enable RS-FEC on HPE Aruba switch ports. Forward error correction improves stability at the full 2km reach.
  • Installation Tips: Hot plug is supported. Avoid rough insertion to protect gold contacts. Maintain proper fiber bend radius to reduce loss.
  • Distance Limit: This model is designed for 2km links. For connections over 2km, select 100G LR4  transceivers.
  • Operating Environment: Stable operation is guaranteed at 0°C–70°C. Keep away from persistent humidity, dust or extreme heat to extend service life.

FAQ

Q1: What scenarios make 100G CWDM4 more suitable than LR4 for Aruba networks?
A1: Our Aruba compatible CWDM4 module is designed for links up to 2km. It provides sufficient optical margin for intra-data center and short campus routes, avoiding unnecessary cost of longer-distance LR4 modules. For leaf-spine and server uplink deployment within a building, it balances performance and budget efficiently.

Q2: Why is RS-FEC recommended for 100G CWDM4 links?
A2: CWDM4 operates with tight optical power budget. RS-FEC compensates for connector loss, splice differences and slight fiber aging. Turning on FEC helps sustain error-free transmission close to the 2km boundary and reduces random packet loss in production networks.

Q3: Can this 100G QSFP28 CWDM4 module work under 4×25G breakout mode?
A3: This standard CWDM4 transceiver only supports native 100G operation. It cannot split into four independent 25G channels. If your network design requires 4×25G breakout, select dedicated breakout QSFP28 models.

Q4: How to solve module alarms on Aruba, Cisco or Huawei equipment?
A4: Most alarms are caused by mismatched EEPROM identification data. Our modules come pre-programmed with Aruba-specific firmware and support free re-programming for other platforms. We complete real-switch validation to realize seamless plug-and-play deployment.

Q5: Why do DDM wavelength values slightly deviate from standard CWDM grid?
A5: Small wavelength offset is permitted within MSA standard tolerance. All our modules are calibrated and screened before shipment. Minor DDM fluctuation will not affect throughput or link stability under normal Aruba operating conditions.

Q6: Do I need an optical attenuator for ultra-short patch cord connections?
A6: Attenuators are generally unnecessary for short patch runs. Our transmit power level is optimized for standard data center patch panels. Only when excessive launch power triggers intermittent errors should you add a matched attenuator after checking module parameters.

Q7: Rx power remains low after fiber cleaning. What troubleshooting steps to follow?
A7: Check ferrules for scratches and cables for sharp bends or crushed ducts. Swap patch cords and test alternative ports to isolate faults. If low receiving power follows the module, our engineering team provides optical testing and after-sales support for bulk customers.

Q8: What does DOM Rx power reading around -40dBm mean?
A8: A reading near -40dBm usually indicates no optical signal arrives at the receiver. Common reasons include disconnected fiber, damaged jumpers or inactive remote transmitter. We provide clear fault isolation procedures to quickly restore data center traffic.

Q9: Are third-party compatible modules less reliable than original HPE Aruba OEM transceivers?
A9: Qualified compatible modules can reach equivalent performance level. Our R0Z30A compatible CWDM4 modules adopt industrial chips and complete optical and compatibility testing. The main gap exists in vendor lock-in and official support contracts instead of basic transmission stability.

Q10: What compliance materials should purchasers request from optical module suppliers?
A10: As a professional optical module manufacturer, we supply RoHS certificates, MSA compliance documents, temperature cycle test records and real-switch compatibility reports. All products support full traceability to satisfy enterprise and data center project compliance demands.
