## Summary description

The BlueOptics QSFP28-100G-ER4-S-BO is a high-speed fiber optic transceiver module with a data rate of 200000 Mbit/s. It features a QSFP56 interface, metal housing, and operates at 3.3V. Weighing 40g, it is designed for data centers and high-performance networking applications.

## Long description

The BlueOptics QSFP28-100G-ER4-S-BO is a 100G fiber optic transceiver module engineered for long-reach, high-throughput network links. Designed for data center and carrier-class environments, this compact metal-cased module supports a 200000 Mbit/s data rate and uses a QSFP56-compatible fiber interface. The transceiver operates at 3.3V and is optimized for reliable transmission over single-mode fiber across extended distances up to 10,000 meters, while its silver metal housing provides mechanical durability and electromagnetic shielding.
Advantages
The module delivers high bandwidth for aggregation and core network segments while maintaining low power operation at industry-standard voltage. Its metal enclosure enhances heat dissipation and physical protection, and the QSFP56 fiber connector ensures compatibility with modern 100G networking hardware. Lightweight construction and standardized form factor facilitate easy installation and hot-swap replacement in rack environments.
Suitable for
Data center uplinks and inter-rack connections
Carrier and metro long-reach optical links
Core and aggregation switches requiring 100G interfaces
High-performance computing network backbones
Key specifications
Data rate: 200000 Mbit/s
Maximum transfer distance: 10000 m (single-mode fiber)
Connector type: QSFP56 fiber interface
Operating voltage: 3.3 V
Housing material and colour: metal, silver
Weight: 0.04 kg
How to use
Install the transceiver into a compatible QSFP28/QSFP56 slot on a switch, router, or media converter following the host device manufacturer’s instructions. Ensure the host supports 100G-ER4 optics and that the link partners are configured for matching speed and modulation. Use single-mode fiber cabling rated for long-reach transmission, check fiber polarity and connector cleanliness before insertion, and allow a brief link negotiation period after insertion. Monitor link status LEDs or management interfaces to confirm proper operation.
Usage recommendations
For reliable long-distance links, use single-mode fiber with appropriate attenuators if required, keep connectors clean using proper fiber cleaning tools, and maintain ambient operating conditions within the host equipment specifications. Verify host compatibility with 100G ER4 optics to ensure optimal performance.
