Description

The Arista QSFP-100G-ZR42 is a 100GBASE-ZR4 QSFP28 optical transceiver engineered for long-reach data centre interconnect, metro, and long-haul network deployments over single-mode fibre. Delivering 100Gbps across four LAN-WDM channels (1295–1309nm) via duplex LC connectors, it achieves up to 80km reach over G.652 duplex SMF — making it the right choice for DCI and campus backbone links that demand maximum distance without external amplification.

Each of the four 25Gbps optical lanes is multiplexed into a single fibre pair, with Digital Optical Monitoring (DOM) providing real-time visibility into temperature, voltage, and optical power. Note that optical attenuation is required on shorter links to protect the receiver, and platform compatibility should be confirmed against the Arista Transceiver and Cable Guide prior to deployment.

Features

- 100GBASE-ZR4 compliant — designed for long-reach single-mode fibre links up to 80km
- 4-channel LAN-WDM optical design multiplexed over a single duplex fibre pair
- Four independent 25Gbps lanes combine to deliver full 100Gbps throughput
- Digital Optical Monitoring (DOM) for real-time visibility into optical and electrical parameters
- Duplex LC connector interface for straightforward fibre patching and integration
- Suited for data centre interconnect (DCI), metro, and long-haul network applications
- Optical attenuation required on short-distance links to protect the receiver
- Platform-specific support — verify compatibility with Arista Transceiver and Cable Guide before deployment

FAQs

Q: What is the maximum transmission distance of the QSFP-100G-ZR42?
A: The QSFP-100G-ZR42 supports a maximum reach of up to 80km over G.652 duplex single-mode fibre (SMF) using four LAN-WDM optical channels.

Q: What connector type and fibre type does this transceiver use?
A: It uses duplex LC connectors and is designed for use with G.652 duplex single-mode fibre. It is not compatible with multimode fibre.

Q: Is optical attenuation required when using this transceiver on short links?
A: Yes. Because the transmitter output power is optimised for long-reach applications, optical attenuation must be inserted on links shorter than the specified minimum distance to prevent receiver saturation or damage.

Q: Does the QSFP-100G-ZR42 support Digital Optical Monitoring (DOM)?
A: Yes. DOM is supported, allowing real-time monitoring of key parameters including optical transmit and receive power, temperature, supply voltage, and laser bias current.

Q: Which Arista platforms support this transceiver?
A: The QSFP-100G-ZR42 has a higher power draw than standard QSFP28 modules and is supported on specific Arista platforms only. Always verify compatibility using the Arista Transceiver and Cable Guide before purchasing.

Q: Can I purchase the Arista QSFP-100G-ZR42 in Australia through IP Trading?
A: Yes. IP Trading is an Australian B2B IT hardware reseller stocking Arista optics including the QSFP-100G-ZR42. Visit iptrading.com.au to place your order or contact the team for volume pricing and compatibility advice.
