Product information

Description

The BlueOptics ET6401-SR4-BO is a QSFP fiber optic network transceiver module designed for 40 Gbit/s links. The module supports multimode fiber transmission with MPO/MTP connectivity in a compact silver housing and weighs approximately 20 g. It complies with CE, RoHS and FCC standards and is intended for high-speed data transmission in networking equipment that supports QSFP 40GBASE-SR4 interfaces.

Advantages

The BlueOptics ET6401-SR4-BO provides a standardized QSFP interface for 40G data rates and a compact form factor that fits into compatible switch, router or storage ports. Its certified compliance with CE, RoHS and FCC ensures regulatory conformity for many deployment environments. The module's multimode MPO/MTP connectivity and support for 40GBASE-SR4 protocols enable short-range high-bandwidth links while keeping signal immunity advantages of fiber optic transmission.

Suitable for

  • High-speed uplinks between switches and aggregation devices
  • Interconnects in data center top-of-rack and spine architectures
  • Storage area network links and high-performance computing clusters
  • Short-reach multimode fiber connections up to typical SR4 distances

Key specifications

  • Interface type: QSFP
  • Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
  • Connector type: MPO/MTP (multimode)
  • Optical wavelength: typical 850 nm for multimode SR4 operation
  • Housing color: silver
  • Weight: 0.02 kg
  • Compliance: CE, RoHS, FCC

How to use

Insert the BlueOptics ET6401-SR4-BO module into a compatible QSFP port on your switch, router or storage device following the host equipment instructions. Connect an appropriate multimode MPO/MTP patch cable between modules or to a compatible breakout or patch panel. Ensure that the host device supports 40GBASE-SR4 and, if required, enables Digital Diagnostic Monitoring (DDM/DOM) to read supply voltage, laser current, optical output and input power and temperature. Observe proper ESD handling and factory guidelines when installing or removing the transceiver.

Usage recommendations

For reliable operation, use quality multimode MPO/MTP fiber and follow the distance limits for SR4 multimode links. Verify host compatibility and, if remote diagnostics are needed, confirm DDM/DOM support in the system. Store and handle the module in ESD-safe conditions and avoid bending or contaminating fiber connectors to maintain link performance.
