## Long description

The BlueOptics TRX100257-BO is a QSFP fiber optic transceiver module designed for high-speed optical data transfer up to 40000 Mbit/s. The module uses a metal housing for mechanical durability, operates at 3.3 V input voltage and has a compact form factor with a weight of approximately 2 g. It implements the QSFP interface and a duplex LC-style optical connection suitable for single-mode fiber links and is intended for use in network equipment that supports 40G QSFP modules.
Advantages
The BlueOptics TRX100257-BO delivers 40 Gbit/s throughput in a QSFP form factor while maintaining low weight and a robust metal enclosure for reliable installation. Its single-mode optical transmission with CWDM-enabled transmitter and receiver supports long-reach links, and the module conforms to common MSA QSFP mechanical and electrical standards to ensure interoperability with compatible network ports. The compact design simplifies integration into switches, routers and other 40G-capable hardware.
Suitable for
 40G Ethernet uplinks between switches and data center aggregation
 High-speed connections for routers, storage systems and load balancers
 Long-reach single-mode fiber links up to multi-kilometer distances
 Environments requiring a QSFP form factor and LC duplex fiber connections
Key specifications
 Interface type: QSFP
 Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
 Connector type: LC duplex (single-mode fiber)
 Operating voltage: 3.3 V input
 Housing: metal enclosure
 Product colour: silver
 Weight: approx. 0.002 kg
 Optical scheme: CWDM-enabled transmitter and receiver for wavelength multiplexing
How to use
Insert the BlueOptics TRX100257-BO into a compatible QSFP slot of a switch, router or other network device that supports 40G QSFP transceivers. Connect single-mode LC duplex fiber patch cords to the module’s LC ports, ensuring correct transmit/receive orientation. Verify that the host device recognizes the transceiver and that link negotiation completes at 40 Gbit/s. Follow the host vendor’s instructions for enabling any required interfaces or configuring link parameters.
Usage recommendations
For optimal performance, use single-mode fiber and high-quality LC duplex patch cords, keep connectors and transceiver optical interfaces clean, and confirm that the network device firmware supports the QSFP module for full compatibility. If digital diagnostic monitoring (DDM/DOM) is required, ensure the host hardware supports the diagnostic functions to access real-time operating parameters.
