100GBASE-ZR4 QSFP28 Compatible Transceiver Description
The EDGE 100G-QSFP28-80 is a multi-vendor compatible 100GBASE-ZR4 QSFP28 optical module for 100 Gigabit Ethernet applications requiring 80km reach over single-mode fiber. It uses four LAN WDM wavelengths at 25 Gbps each (103.125 Gbps line rate including 64B/66B encoding overhead) and is compatible with switching and routing platforms from Cisco, Arista, Juniper, and others.
Transmission uses LAN WDM technology across four discrete wavelength channels: 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm. Each channel carries 25.78125 Gbps (25 Gbps payload), combining to 100 Gbps aggregate Ethernet throughput. These are the same O-band LAN WDM channels used by 100GBASE-LR4, but ZR4 achieves greater reach through higher-power EML transmitters and more sensitive receiver components.
The 100G-QSFP28-80 is rated for a 30dB maximum optical link budget with FEC enabled, supporting transmission distances up to 80km over OS2 single-mode fiber. This 30dB budget accounts for fiber attenuation, connector losses, and splice losses across metropolitan and regional spans. FEC (Forward Error Correction) must be supported — check your platform documentation for host-side FEC configuration requirements.
This is a hot-pluggable QSFP28 module with dual LC/UPC connectors for single-mode fiber. It fits standard QSFP28 cages and is compliant with QSFP28 Multi-Source Agreement (MSA) mechanical and electrical specifications, compatible with network equipment that accepts QSFP28 form-factor optics.
DDM/DOM (Digital Diagnostic Monitoring) provides real-time readings for optical power, temperature, supply voltage, and bias current via the host management interface. Operating temperature range is 0 to 70°C (commercial grade). Maximum power consumption is 6.5W — this is a high-power QSFP28 module, so verify your switch supports high-power QSFP28 cages before deployment. FEC is required for rated 80km 100GBASE-ZR4 performance.
The 100G-QSFP28-80 conforms to the 100GBASE-ZR4 MSA for 100 Gigabit Ethernet over single-mode fiber at 80km, and to the QSFP28 MSA for mechanical and electrical interoperability. The module is RoHS compliant. O-band operation (1295-1309nm) means the signal is not amplifiable by C-band EDFAs — this module is intended for unamplified dark fiber spans.
Common deployments include metro network backbone connections, regional carrier interconnects, data center interconnect (DCI) over dark fiber, and enterprise WAN links requiring 80km single-mode fiber spans. ZR4 fills the gap between ER4 Lite (40km) and the 100km reach of our ZR4+ module (100G-QSFP28-100P) for networks that need more distance without moving to coherent optics.
Every 100G-QSFP28-80 unit is tested before shipment: TX/RX power verification, BER testing, and DDM accuracy checks. Modules ship in anti-static packaging with test reports available on request.
Frequently Asked Questions
What does 100GBASE-ZR4 mean?
100GBASE-ZR4 is an industry MSA (Multi-Source Agreement) for 100 Gigabit Ethernet long-reach transmission over single-mode fiber. It uses four LAN WDM wavelengths (1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm) at 25 Gbps each. The ZR designation indicates extended reach beyond ER4, typically 80km. ZR4 operates with FEC (Forward Error Correction) to maintain signal integrity at these distances. Note that 100GBASE-ZR4 (four-wavelength, O-band, intensity-modulated) is a different technology from 100GBASE-ZR (single-wavelength coherent, C-band, defined in IEEE 802.3ct).
What is the difference between 100GBASE-ZR4 and 100GBASE-ZR4+?
100GBASE-ZR4 covers up to 80km with a 30dB link budget. ZR4+ is a vendor-extended designation (not a formal standard) for modules that exceed the 80km ZR4 reach. Our 100G-QSFP28-100P ZR4+ module is rated for 100km with a 34dB link budget. Both use the same four LAN WDM wavelengths and LC duplex connector. If your span is between 80km and 100km, the 100G-QSFP28-100P is the appropriate choice.
Does 100GBASE-ZR4 require FEC?
Yes, FEC (Forward Error Correction) is needed for ZR4 to achieve its rated 80km reach. Some modules handle FEC internally, while others rely on host-side RS-FEC enabled on the switch or router port. Check with your platform documentation whether host-side FEC must be explicitly enabled. Unlike shorter-reach LR4, ZR4 operates closer to the receiver sensitivity limit, and FEC corrects bit errors introduced by attenuation over 80km of single-mode fiber.
What fiber type and connectors does the 100G-QSFP28-80 use?
The 100G-QSFP28-80 uses OS2 single-mode fiber (SMF) with LC/UPC duplex connectors. It is not compatible with multi-mode fiber. The four LAN WDM wavelengths operate in the O-band (1295-1309nm). Clean and inspect patch cables before installation — contaminated connectors are a common cause of link budget problems on 80km spans.
Is the 100G-QSFP28-80 compatible with Cisco, Arista, and Juniper switches?
The 100G-QSFP28-80 works across platforms that accept 100GBASE-ZR4 QSFP28 optics. For switches with vendor-specific transceiver validation (Cisco, Arista, Juniper, etc.), select the required compatibility from the dropdown on this page. Each variant is programmed with vendor-recognized EEPROM data for that platform.
