Product information

Description

The BlueOptics QSFP-40G-XSR4-CT-BO is a multimode fiber optic QSFP transceiver module designed for 40 Gbit/s data links. It operates at 850 nm and uses an MPO/MTP connector in a QSFP form factor to support short-reach 40GBASE-ESR4 links. The module is built to industry MSA specifications, offers a compact silver housing, and has a rated MTBF of 3,000,000 hours. Weighing approximately 40 g and supporting up to 40,000 m nominal transfer distance in its specifications, it is intended for use in switches, routers, storage systems and other networking hardware that accept compatible QSFP modules.

Advantages

The transceiver provides a standardized QSFP interface and MPO/MTP connectivity for easy integration into existing multimode fiber infrastructures. It supports simultaneous transmit and receive channels using 850 nm optics, includes digital diagnostic monitoring (DDM/DOM) for real-time operational data, and is manufactured using industry-grade components for extended service life. Compliance with common MSA profiles and functional testing on supported hardware platforms helps ensure compatibility with devices that accept Centec-compatible QSFP modules.

Suitable for

  • Data center uplinks and spine-leaf interconnects over multimode fiber
  • Switch-to-switch and switch-to-router 40G connections
  • High-bandwidth storage area network (SAN) links and aggregation ports
  • Environments requiring optical links with DDM/DOM monitoring

Key specifications

  • Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
  • Optical wavelength: 850 nm
  • Connector type: MPO/MTP (multifiber)
  • Supported standard: 40GBASE-ESR4 (short-reach multimode)
  • Form factor: QSFP
  • Housing colour: Silver
  • Weight: 0.04 kg
  • Mean time between failures (MTBF): 3,000,000 hours
  • Digital Diagnostics Monitoring (DDM/DOM): supported (MSA compliant)

How to use

Install the QSFP transceiver into a compatible QSFP slot on a switch, router or other network device after verifying vendor compatibility. Connect an MPO/MTP multimode patch cable between the module and the corresponding patch panel or transceiver at the remote end, ensuring correct polarity and fibre type. If the host system supports DDM/DOM, monitor voltage, temperature, transmitter/receiver power and other diagnostic values via the device management interface to confirm proper operation. Always follow electrostatic discharge (ESD) precautions when handling the module and keep connector endfaces clean to maintain signal quality.

Usage recommendations

Use this QSFP module with multimode OM3/OM4 patching and MPO/MTP cabling for optimal short-reach 40G performance. Verify compatibility with the target hardware vendor and enable digital diagnostics if available for proactive monitoring. Store and handle the module in a dust-free environment and inspect connector endfaces before insertion to prevent signal loss.
