Barrow Mods 100GBASE-LR4 QSFP28 Optical Transceiver Module 2 in 1 accessory

SKU CH-3RVM-AXZRB

A 100GBASE-LR4 QSFP28 transceiver delivers 100 Gbps over 10 km single-mode fibre with 3.5 W maximum power draw and real-time digital optical monitoring

  • 100 Gbps throughput over 10 km single-mode fibre
  • Low 3.5 W draw extends module lifespan
  • Real-time DDM enables instant link diagnostics
  • Hot-pluggable QSFP28 MSA cuts maintenance downtime
  • RoHS-6 compliant and IEEE 802.3bm certified

100GBASE-LR4 QSFP28 Transceiver

This 100GBASE-LR4 QSFP28 optical transceiver module delivers 100 Gbps connectivity over single-mode fibre up to 10 km. It uses a 1310 nm wavelength with duplex LC connectors and includes digital diagnostic monitoring. The module draws a maximum of 3.5 W and is built with a high-performance chip for reliability. It suits network engineers upgrading 100 GbE links in data-centre or campus environments.

Compatibility and Port Requirements

Verify that your switch or router accepts QSFP28 modules coded for Cisco QSFP-100G-LR4-S or Meraki MA-QSFP-100G-LR4. The host port must support the IEEE 802.3bm 100GBASE-LR4 electrical interface and provide a QSFP28 cage with adequate airflow for 3.5 W heat dissipation. Confirm the fibre plant is OS2 single-mode with duplex LC patching and that link distances do not exceed 10 km. The module is hot-pluggable and RoHS-6 compliant for straightforward installation.

Build Integration and Benefits

The transceiver fits directly into any standard QSFP28 slot, freeing you from fixed-port 100 GbE line cards. Its MSA-compliant EEPROM coding ensures recognition across multiple vendor platforms tested in the supplier's compatibility lab. Digital optical monitoring gives real-time visibility of received and transmitted power, temperature and voltage for proactive maintenance. The low 3.5 W draw reduces aggregate chassis power and cooling load compared with higher-consumption alternatives.

Highlights

  • 100 Gbps throughput over 10 km single-mode fibre
  • Low 3.5 W draw extends module lifespan
  • Real-time DDM enables instant link diagnostics
  • Hot-pluggable QSFP28 MSA cuts maintenance downtime
  • RoHS-6 compliant and IEEE 802.3bm certified

Questions about this item

Does the box contain the patch cables or only the transceiver?

The boxed module is supplied alone; duplex LC single-mode patch cables must be purchased separately.

Which distance rating fits a 10 km campus link?

The LR4 variant is specified for 10 km over single-mode fibre at 1310 nm.

What does the 3.5 W figure mean for switch power budgeting?

Each occupied QSFP28 port draws up to 3.5 W, so plan the chassis power supply accordingly.
