Description

The 100GBASE-PLRL4 QSFP28 optical transceiver delivers dual-rate 100G/40G operation over parallel single-mode fibre (SMF) at 1310nm, reaching up to 2km via an MPO-12 APC connector. Designed for data centre core interconnects, HPC fabrics, and ISP aggregation, it supports 4x25G breakout to interoperate with 25GBASE-LR links and 4x10G breakout for flexible infrastructure integration — making it an ideal fit for Arista 100G QSFP-enabled platforms.

Compliant with the 100G-PLR4L MSA and IEEE 802.3bm, this module features Digital Optical Monitoring (DOM) via I2C for real-time diagnostics and a hot-swappable QSFP28 form factor for minimal downtime during deployment. Maximum power consumption is just 3.5W, and the commercial operating temperature range of 0°C to 70°C suits standard data centre environments.

FAQs

Q: What fiber type and maximum distance does the QSFP-100G-PLRL4 support?
A: The QSFP-100G-PLRL4 operates over parallel single-mode fibre (SMF) and supports distances up to 2km using an MPO-12 APC connector. It uses four wavelength lanes centred around 1310nm.

Q: Does this transceiver support breakout cabling?
A: Yes. The QSFP-100G-PLRL4 supports 4x25G breakout to interoperate with 25GBASE-LR links (up to 2km each) and 4x10G breakout operation, giving you significant flexibility in mixed-speed environments.

Q: What is the dual-rate capability and how is it useful?
A: This module operates at both 100G and 40G, allowing the same transceiver to be deployed across platforms running either speed. This simplifies sparing and reduces inventory costs in environments transitioning from 40G to 100G.

Q: Are there any FEC requirements for this transceiver?
A: Yes. Forward Error Correction (FEC) is supported, but both ends of a link must be configured with the same FEC mode for the link to come up successfully. Verify FEC settings on connected Arista platforms before deployment.

Q: Is this transceiver compatible with Arista switches and routers?
A: Yes. The QSFP-100G-PLRL4 is designed for use with Arista platforms supporting 100G QSFP28 ports. Always verify compatibility with your specific Arista EOS software version and platform via Arista's transceiver compatibility matrix.

Q: Can I purchase the Arista QSFP-100G-PLRL4 in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller supplying Arista transceivers and networking hardware with expert pre-sales support. Visit the site or contact the team directly to confirm availability and pricing.
