  • Low 2.5W power draw extends module lifespan
  • Operates reliably from 0 to 70°C commercial range
  • Real-time digital optical monitoring enables quick diagnostics
  • 4km reach over 1310nm single-mode fibre with MPO-12/APC
  • Hot-pluggable QSFP+ compliant to SFF-8436 and MSA standards

40GBASE-PIR4 QSFP+ Transceiver

This 40GBASE-PIR4 QSFP+ optical transceiver module connects Arista-compatible switches and routers over single-mode fibre. It suits network engineers building or extending 40 Gbps links in data-centre or campus environments. The hot-pluggable QSFP+ form factor fits standard ports without tools. Buyers who need longer reach or different connector types should choose another module.

Sustained-load behaviour

A built-in high-performance chip limits maximum power draw to 2.5 W, helping the module run steadily across the commercial temperature range of 0 to 70 °C (32 to 158 °F). Four CWDM lanes each carry up to 11.2 Gbps, and real-time digital optical monitoring reports signal quality continuously. The design supports 40 Gbps to 4 × 10 Gbps breakout for flexible link aggregation.

Installation and common issues

The hot-pluggable QSFP+ form factor inserts directly into compliant ports; no tools or system reboot are required. An MPO-12/APC connector mates with standard single-mode patch cords up to 1.4 km. EEPROM coding is pre-programmed for Arista QSFP-40G-PLRL4 compatibility, reducing misidentification risk. Installers must verify that the host device accepts third-party coded modules, as some vendors lock ports to first-party optics.

Questions about this item

How much power does the 40GBASE-PIR4 module draw and what temperature range does it handle when running continuously?

The module draws a maximum of 2.5 W and operates within a commercial temperature range of 0 to 70 °C (32 to 158 °F).

What cabling and connector type must I already have to use this transceiver?

You need single-mode fibre terminated with an MPO-12/APC connector to match the module's interface.

Will this QSFP+ transceiver work in an older switch that only supports 40GBASE-LR4?

Yes, the module is compliant with the 40GBASE-LR4 standard and the SFF-8436 QSFP+ MSA, so it will interoperate with legacy 40G LR4 ports.
