## Summary description

The BlueOptics TOM-100G-Q-LR4-BO is a QSFP28 fiber optic transceiver module designed for high-speed data transfer at 100000 Mbit/s. It is compliant with FCC and RoHS standards, ensuring quality and safety. With a compact QSFP28 form factor and a weight of only 40 g, it is suitable for various networking applications.

## Long description

The BlueOptics TOM-100G-Q-LR4-BO is a QSFP28 fiber optic transceiver module designed for 100 Gbit/s data transmission over single-mode fiber. The module follows MSA QSFP28 form-factor standards, features an LC duplex optical interface and is compliant with FCC and RoHS requirements. With a compact silver housing and a weight of approximately 40 g, this transceiver is intended for integration into network equipment that accepts QSFP28 modules and supports 100GBASE-LR4 links up to several kilometers.
Advantages
This QSFP28 transceiver supports 100000 Mbit/s operation and implements CWDM-based transmit and receive channels suitable for 100GBASE-LR4 applications. The module provides Digital Diagnostics Monitoring (DDM/DOM) capability for real-time monitoring of supply voltage, laser bias current, optical transmit power, received optical power and temperature when the host hardware supports it. Manufactured to MSA-compatible specifications, the transceiver is intended as a compatible alternative for platforms that support the original LR4 QSFP28 modules and is optimized for long service life and stable optical performance.
Suitable for
100G Ethernet uplinks and core switching
High-speed data center interconnects over single-mode fiber
Fibre Channel over Ethernet and SDH/SONET transport
Replacement or spare transceiver for compatible networking hardware
Key specifications
Form factor: QSFP28
Data rate: 100000 Mbit/s (100 Gbit/s)
Optical standard: 100GBASE-LR4 (CWDM channels over single-mode fiber)
Connector type: LC duplex
Monitoring: Digital Diagnostics Monitoring (DDM/DOM) support (if host supports SFF-8472)
Color/finish: Silver metal housing
Weight: approx. 0.04 kg
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 slot on a switch, router or optical device while the host device is powered according to the vendor instructions. Connect LC duplex single-mode fiber patch cords to the module’s LC port, ensuring correct TX/RX orientation. Verify link status and, if available, read DDM parameters from the host management interface to confirm optical power levels and module temperature. Follow the network equipment manufacturer’s guidelines for hot-swap procedures, ESD precautions and firmware compatibility.
Usage recommendations
Use single-mode LC duplex patch cables and verify that the connected equipment supports 100GBASE-LR4 and QSFP28 modules. To maintain optical performance, keep connectors clean, avoid tight bends in fiber runs, and confirm that the host system supports DDM if remote monitoring is required.
