ARCTIC QSFP28 100G LR4 1310nm 10km LC DOM 2 in 1 accessory
A QSFP28 transceiver delivering 100 Gbps over 10 km of single-mode fibre at 1310 nm with LC duplex and DOM support
- 100 Gbps throughput for high-density links
- 10 km reach over single-mode fibre at 1310 nm
- LC duplex connector enables hot-pluggable deployment
- Digital diagnostics via I2C per QSFP28 MSA
- Coded for Arista Networks QSFP-100G-LR4 compatibility
Arista-coded 100G LR4 transceiver
This QSFP28 module is coded for Arista Networks QSFP-100G-LR4 compatibility and delivers 100Gbps Ethernet over single-mode fibre. It targets network engineers who need a drop-in LR4 optic for 10 km campus or metro links. Buyers who require multi-mode SR4 reach or third-party switch coding should look elsewhere.
Sustained 10 km single-mode operation
The 1310nm LAN-WDM optics maintain link integrity across the full 10 km distance without the signal fade sometimes seen in shorter-reach modules under continuous load. Digital diagnostics over the I2C interface expose real-time temperature, voltage and optical power so capacity planning relies on measured data rather than speculation.
Hot-pluggable LC duplex installation
The LC duplex connector and hot-pluggable QSFP28 form factor allow insertion or removal without powering down the switch, reducing change-window risk. The most common issue is fibre-end contamination; a one-click cleaner and visual fault locator should be used before every mating to avoid unnecessary troubleshooting.

Questions about this item
How much heat does the 100G QSFP28 LR4 generate when running continuously?
The module operates at 1310nm wavelength over 10km single-mode fibre with LC duplex connector and supports digital optical monitoring via I2C for real-time temperature tracking.
What equipment is required to use this QSFP28 transceiver?
A QSFP28-compatible port coded for Arista Networks QSFP-100G-LR4, single-mode fibre with LC duplex connectors, and a host supporting IEEE 802.3bm CAUI-4 electrical interface.
Will this Arista-coded QSFP28 work alongside older 10G SFP+ modules in the same chassis?
The transceiver follows QSFP28 MSA form factor and hot-pluggable design, allowing installation in compatible ports without disrupting adjacent modules running at different speeds.
