A QSFP-100G-ZR Optical Transceiver Module


The QSFP-100G-ZR is a type of optical transceiver used for transmitting 100 Gigabit Ethernet (100GbE) data over long distances, typically up to 80 kilometers (km) on single-mode fiber (SMF).

Here’s a breakdown of the key features:

  • Form Factor: QSFP (Quad Small Form-Factor Pluggable) – This means it’s a hot-swappable transceiver that plugs into a QSFP port on a network switch or router.
  • Data Rate: 100 Gigabit Ethernet (100GbE) – It can transmit and receive data at a rate of 100 gigabits per second.
  • Reach: Up to 80 km – This allows for long-distance connections between data centres, enterprise locations, or service provider buildings.
  • Wavelength: 1310 nm – It operates in the O-band of the optical spectrum, where fibre optic dispersion is minimal.
  • Technology: Traditional direct-detect with NRZ (Non-Return to Zero) modulation – This is a well-established technology for data transmission over fibre.
  • Other Features:
    • Uses a Semiconductor Optical Amplifier (SOA) to boost the signal for longer distances.
    • Employs 4 independent channels, each operating at 25 Gbps.

Overall, the QSFP-100G-ZR is a versatile option for high-bandwidth, long-distance data transmission in data centres, enterprise networks, and service provider applications.

Here are some of the technical specifications of the QSFP-100G-ZR transceiver:

  • Data Rate:125 Gbps (including overhead)
  • Wavelength: 1310 nm (nominal)
  • Reach: Up to 80 km over 9/125 μm SMF (Single-Mode Fiber) with FEC (Forward Error Correction)
  • Fiber Type: Single-Mode Fiber (SMF)
  • Interface: 4-channel Full-Duplex QSFP28 MSA compliant
  • Transmitter Type: 4 x 25Gbps EML (Electroabsorption Modulated Laser) based LAN-WDM (Local Area Network – Wavelength Division Multiplexing)
  • Power Supply: Single 3.3V
  • Power Dissipation: Less than 6W
  • Operating Temperature: 0°C to 70°C (commercial temperature range)

Additional points to consider:

  • Requires Host-Based RS-FEC (Reed Solomon Forward Error Correction) for error-free transmission.
  • Provides DOM (Digital Optical Monitoring) for real-time monitoring of optical parameters.
  • May have higher power consumption compared to other QSFP-100G options due to the use of SOA for extended reach.
