Description

The QSFP-100G-LR-ARISTA-BCC is a drop-in compatible replacement for the Arista QSFP-100G-LR-ARISTA. This single-lambda QSFP28 transceiver operates plug-and-play in Arista platforms equipped with 100G QSFP28 ports supporting 100GBASE-LR operation. - Complies with IEEE 802.3cd 100GBASE-LR and 100G Lambda MSA, ensuring interoperability with 400GBASE-LR4 breakout scenarios and single-lambda 100G infrastructure - QSFP28 form factor delivering 100G over single-mode fibre using 1310nm single wavelength, PAM4 modulation, duplex LC connector, 10km reach - Converts 4x25G NRZ electrical lanes to 1x100G PAM4 optical signal via onboard DSP and FEC, enabling simplified fibre infrastructure compared to 4-wavelength LR4 - DOM support for real-time monitoring of optical power, temperature, bias current, and supply voltage via I2C interface per QSFP28 MSA - Hot-swappable design allows installation without service interruption in QSFP28 MSA-compliant ports

Features

• IEEE 802.3cd 100GBASE-LR compliance guarantees electrical and optical interoperability with 100G single-lambda infrastructure and breakout compatibility with 400GBASE-LR4 at one wavelength per 100G channel
• Single-lambda architecture with PAM4 modulation and onboard DSP performs 4x25G NRZ to 1x100G PAM4 conversion, reducing fibre count to one duplex pair compared to parallel 4-wavelength solutions
• Integrated forward error correction (FEC) enables 10km reach over standard G.652 single-mode fibre within typical link budgets, subject to actual fibre loss and splice conditions
• Hot-swappable QSFP28 MSA form factor allows field installation and replacement without powering down the host system or interrupting adjacent ports
• Digital optical monitoring via I2C provides real-time access to transmit and receive optical power, module temperature, laser bias current, and supply voltage for link diagnostics and threshold alarming
• Cooled EML laser transmitter and linear receiver maintain stable performance across the commercial temperature range while meeting eye mask and TDECQ specifications for 100G PAM4 signaling
• Duplex LC/UPC connector interface integrates with existing single-mode cabling infrastructure, offering simpler breakout and patching compared to parallel-fibre MPO solutions

FAQs

Q: Will this work in place of the Arista QSFP-100G-LR-ARISTA?
A: Yes. This transceiver is engineered as a plug-and-play replacement for the Arista QSFP-100G-LR-ARISTA, matching the IEEE 802.3cd 100GBASE-LR single-lambda specification, QSFP28 form factor, 1310nm wavelength, and 10km reach over single-mode fibre.

Q: Which Arista platforms support this single-lambda 100GBASE-LR module?
A: This module is compatible with Arista switches and routers offering QSFP28 ports configured for 100G operation with 100GBASE-LR support. Consult the Arista Transceiver and Cable Compatibility Guide for your specific platform and software version to confirm 100GBASE-LR single-lambda operation, as some platforms may require particular EOS releases for full feature support.

Q: How does this single-lambda 100GBASE-LR differ from 100GBASE-LR4, and why does the architecture matter?
A: 100GBASE-LR4 uses four separate LAN WDM wavelengths (1295.56, 1300.05, 1304.58, 1309.14 nm) multiplexed over a duplex fibre pair, whereas this single-lambda 100GBASE-LR module transmits the entire 100G signal at one wavelength (1310nm) using PAM4 modulation. The single-lambda design simplifies breakout compatibility with 400GBASE-LR4 systems, where each 100G lambda from a 400G port can connect directly to a single-lambda 100G module without wavelength mismatch, enabling incremental 100G to 400G migration.

Q: Does this module require host-side FEC, and what happens if FEC is disabled?
A: Yes, this module relies on host-side FEC to achieve the specified 10km reach and bit error rate performance over PAM4 signaling. The onboard DSP integrates FEC processing, but the host must enable FEC on the QSFP28 electrical interface. Disabling FEC will significantly reduce reach and increase bit error rates, potentially preventing link establishment at distances approaching 10km or over marginal fibre.

Q: Can this transceiver interoperate optically with 100GBASE-LR4 modules at the far end of the link?
A: No. Despite both reaching 10km, single-lambda 100GBASE-LR (1310nm PAM4, one wavelength) and 100GBASE-LR4 (four LAN WDM wavelengths) use incompatible optical encoding. A single-lambda module at one end must connect to another single-lambda module at the far end. However, the single-lambda module will interoperate with one wavelength channel from a 400GBASE-LR4 transceiver in breakout mode, provided the 400G side uses compatible wavelength mapping.
