## Summary description

The BlueOptics QSFP-100G-ER4-S-BO is a fiber optic transceiver with a 40000 Mbit/s data rate. It features a QSFP28 interface, compact design, and high reliability with an MTBF of 3000000 hours. Weighing 40 g, it is ideal for efficient networking applications.

## Long description

The BlueOptics QSFP-100G-ER4-S-BO is a fiber optic transceiver designed for high-speed networking with a maximum data rate of 40000 Mbit/s. The module uses a QSFP28-compatible form factor with LC fibre connectors and a compact silver housing weighing approximately 40 g. With an MTBF of 3,000,000 hours, this transceiver is built for continuous operation and long-term deployment in data centre and carrier-grade environments.
Advantages
The transceiver provides a stable 40 Gbit/s optical link using ER4-class transmission distance capability, allowing long-reach connections up to the specified maximum transfer distance. Its QSFP28-compatible interface supports hot-pluggable installation and is compatible with common hardware platforms. The unit’s metal housing and industry-standard LC connector ensure mechanical robustness and low insertion loss. Extended mean time between failures (MTBF 3,000,000 hours) contributes to reduced maintenance cycles and higher availability for critical links.
Suitable for
 Long-reach optical uplinks between data centres and aggregation sites
 High-capacity switch-to-switch or router-to-router connections
 Carrier and metro networks requiring ER4-class single-mode fibre links
 Enterprise backbones and storage area network (SAN) interconnects
Key specifications
 Maximum data transfer rate: 40000 Mbit/s
 Maximum transfer distance: 40000 m (ER4-class long reach)
 Form factor: QSFP28-compatible transceiver
 Connector type: LC duplex
 Optical type: single-mode fibre, ER4 optics (transmit/receive at 1310 nm range)
 Operating reliability: MTBF approximately 3,000,000 hours
 Housing colour/finish: silver metal enclosure
 Weight: ~0.04 kg
How to use
Install the QSFP-100G-ER4-S-BO into a QSFP/QSFP28-compatible socket on a switch, router or transceiver-capable network device while the host port is powered and supports the required optical mode. Connect LC duplex single-mode patch cables to the module’s LC ports, observing correct polarity for transmit and receive channels. Allow the device and transceiver to negotiate link parameters; monitor link status through the host system. For modules with digital diagnostics support, use the host management interface to check optical power, temperature and supply voltage where supported by the equipment.
Usage recommendations
Use single-mode LC duplex fibre patch cables of appropriate grade and quality for ER4 links and ensure connectors are clean before mating. Verify that the network equipment firmware supports third-party QSFP transceivers and enable Digital Diagnostics Monitoring (DDM/DOM) if available to facilitate remote monitoring and troubleshooting. Store spare transceivers in anti-static packaging and avoid exposing optical ports to dust or moisture when not in use.
