Description

The Arista QSFP-100G-FR-Arista is a 100GBASE-FR1 QSFP28 optical transceiver designed for 100 Gigabit Ethernet connectivity over single-mode fiber up to 2km. Using a single 1310nm wavelength with PAM4 modulation and on-board FEC, this module converts 4x25G NRZ electrical signals to a single 100G optical channel. Compliant with QSFP28 MSA, IEEE 802.3cd, and 100G Lambda MSA standards, it features digital diagnostics monitoring and hot-swappable installation, making it ideal for data center interconnects, enterprise networking, and 400G to 100G breakout applications.

Features

100GBASE-FR1 single-lambda transmission over duplex single-mode fiber
- PAM4 modulation technology for high-speed transmission over a single wavelength
- Integrated DSP-based gearbox converts 4x25G NRZ to 1x50Gbaud PAM4 signal
- On-board Forward Error Correction (FEC) and retimer for enhanced link performance
- Digital Diagnostics Monitoring (DDM) for real-time monitoring of optical power, temperature, bias current, and voltage
- Hot-swappable and hot-pluggable for easy installation and maintenance
- Cooled EML (Electro-absorption Modulated Laser) transmitter for stable performance
- Compliant with QSFP28 MSA, IEEE 802.3cd, and 100G Lambda MSA standards

FAQs

Q: What is the maximum transmission distance for the QSFP-100G-FR-Arista?
A: This transceiver supports up to 2km transmission over OS2 single-mode fiber when Forward Error Correction (FEC) is enabled on the host system.

Q: Is this transceiver compatible with Arista switches and routers?
A: Yes, the QSFP-100G-FR-Arista is designed to be compatible with Arista 100G QSFP28 ports across enterprise switches, routers, and data center platforms. Verify specific platform support in Arista's Transceiver and Cable Guide.

Q: Can this 100G transceiver be used in 40G QSFP+ ports?
A: No, this is a 100G QSFP28 transceiver and requires a 100G QSFP28 port with 4x25G electrical lanes. It is not backward compatible with 40G QSFP+ interfaces.

Q: Does this transceiver support breakout configurations?
A: This specific FR1 transceiver operates as a single 100G channel. For breakout applications (400G to 4x100G), you would need 400G transceivers with appropriate breakout optics on the 400G side.

Q: What is the power requirement for this transceiver?
A: The QSFP-100G-FR-Arista has a maximum power consumption of 4.5W and follows QSFP28 MSA high-power specifications. Most Arista 100G QSFP28 ports support transceivers drawing up to 4.5W.
