Product Description and Technical Highlights of Juniper QSFP-100G-ZR4 (Model 740-120240) Optical Module:
1. Core Function: 100Gbps (4×25Gbps wavelengths) single-mode fiber (SMF) transceiver module.
Transmission Distance: ≥80 km (Compliant with IEEE 802.3cu 100GBASE-ZR4 / OpenZR+ standards).
Wavelength and Multiplexing Technology: Utilizes CWDM4 wavelengths (1271nm, 1291nm, 1311nm, 1331nm), transmitting over a single fiber via wavelength division multiplexing (WDM).
Interface and Protocol:
QSFP28 packaging, supporting 100GBASE-ZR4.
Compatible with OTU4 standard (for telecommunication transmission).
Fiber Type: Single-mode fiber (SMF), requires LC duplex interface.
Typical Application Scenarios: Metropolitan area network backbone, long-distance interconnection in data centers, core telecommunication networks.
Key Parameters: Transmit Power: 0 to +5 dBm, Receive Sensitivity: ≤-21 dBm, Power Consumption: < 8W, Operating Temperature: 0°C to 70°C (commercial grade).
Advantages: High density, low power consumption, supports ultra-long distances without the need for relays. 2. QSFP-100G-80KM
Core Function: 100Gbps single-mode optical transceiver module (non-CWDM4 solution).
Transmission Distance: ≥80 km (based on ePAM4 modulation technology).
Wavelength and Modulation: Single wavelength 1310nm, using PAM4 high-order modulation technology (non-traditional 4-wavelength solution).
Interface and Protocol: QSFP28 packaging, supports 100GBASE-ER4 Lite or similar proprietary standards. Switch support for PAM4 modulation and demodulation is required.
Optical Fiber Type: Single-mode fiber (SMF), LC duplex interface.
Typical Application Scenarios: Ultra-long-distance data center interconnection (DCI), low-cost alternative to traditional ZR4.
Key Parameters: Transmit power: -4 to +4 dBm, receive sensitivity: ≤ -15 dBm, power consumption: < 6W, operating temperature: 0°C to 70°C.
Advantages: Lower cost (single-wavelength laser), simplified fiber management (single pair of fibers). Comparison and summary
Features: QSFP-100G-ZR4 (740-120240), QSFP-100G-80KM
Technical Standards: CWDM4 / OpenZR+, ePAM4 (proprietary solution)
Number of Wavelengths: 4 wavelengths (1271/1291/1311/1331nm), single wavelength (1310nm)
Modulation Method: NRZ, PAM4
Protocol Compatibility: 100GBASE-ZR4, OTU4, requires PAM4 support from the equipment
Number of Fiber Pairs: Single-fiber bidirectional (Bidi), Single-fiber bidirectional (Bidi)
Cost: Higher (four laser channels), Lower (single laser channel)
Deployment Complexity: Requires dispersion compensation for long-distance scenarios, simplifies fiber optic links
Usage Notes
1. Compatibility: Ensure compatibility with Juniper switches/routers (such as MX, PTX, QFX series).
2. Fiber Requirements: Must use OS2 single-mode fiber, with LC-LC patch cords.
3. Dispersion Management: ZR4 requires a dispersion compensation module (DCM) for links longer than 80km.
4. Diagnostic Monitoring: Supports DDM/DOM functions, allowing real-time data such as optical power and temperature to be viewed through Junos CLI (command: `show interfaces diagnostics optics`).
