100G DWDM QSFP28 ZR2 (Color A)

The 100G DWDM QSFP28 ZR2 (Color A) is a 100-Gigabit Ethernet single-mode transceiver for long-reach DWDM links over existing C-band plant. It carries 4×25G NRZ over a duplex LC interface and presents a CAUI-4 (4×25.78 Gbps) electrical host—ideal for metro access/aggregation, campus DCI, and 100G wavelengths through DWDM MUX/DEMUX systems.

• Standards & Management

  • Optical: 100G DWDM ZR2 (vendor MSA class)

  • Electrical host: CAUI-4 (4×25.78 Gbps NRZ)

  • Module management: SFF-8636 DOM/DDM (diagnostics, alarms)

• Optics & Reach

  • Band: DWDM C-band, ITU-T grid (50/100 GHz)

  • Wavelength: Color A (factory-set DWDM channel; tunable/fixed options by model)

  • Connector/Fiber: LC duplex, OS2 SMF

  • Typical reach: up to 80 km (link-budget dependent; amplifier/FEC may be required)

• Performance & Features

  • Low BER with host FEC; PRBS/loopback (platform-dependent)

  • Supports operation through passive DWDM MUX/DEMUX/OADM

  • Telemetry: TX/RX power, temperature, voltage, bias

• Reliability & Compliance

  • Case temperature: 0 to +70 °C (commercial)

  • Laser safety: Class 1 (IEC 60825-1)

  • RoHS/REACH compliant

• Use Cases

  • 100G wavelength over DWDM rings/chains

  • Metro DCI and inter-campus backbones up to 80 km

  • Aggregation uplinks where LC-duplex simplifies cabling

Notes: Specifications vary by version (fixed vs. tunable channel, output power, receiver type). Confirm channel map and optical budget against your DWDM plan.
