ARENTI

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

SKU CH-HDBC-705T6

A 100GBASE-LR4 QSFP28 transceiver with 3.5W max power, 1310nm wavelength, 10km reach over duplex LC single-mode fibre, DDM monitoring and IEEE 802.3bm compliance

  • 100 Gbps long-range connectivity up to 10 km
  • Low 3.5 W power draw extends module lifespan
  • Real-time DDM diagnostics simplify link troubleshooting
  • Hot-pluggable QSFP28 design enables zero-downtime swaps
  • RoHS-6 compliant for regulated-environment deployment

100GBASE-LR4 QSFP28 transceiver for long-reach links

The ARENTI module delivers 100 Gbps over single-mode fibre at 1310 nm for distances up to 10 km. It uses a duplex LC connector and conforms to the QSFP28 MSA form factor, making it suitable for data-centre and campus uplinks that require extended reach.

Sustained operation at 3.5 W

Maximum power draw is rated at 3.5 W, supporting prolonged service life in densely populated switch chassis. Real-time digital optical monitoring provides continuous visibility of temperature, voltage and optical power, allowing operators to detect degradation before a link fails.

Verify switch port coding

The module is programmed for compatibility with Extreme 10403 and equivalent 100G-QSFP28-LR4-10KM equipment, so confirm the target switch accepts third-party EEPROM codes. Ensure the link uses duplex single-mode fibre with LC connectors and that the optical budget matches the 10 km distance.
