## Long description

The BlueOptics BO28L859S1D is a fiber optic network transceiver module designed for 100 Gbit/s applications. It uses a QSFP28 interface and supports multimode fiber connections with an MPO/MTP-style optical connector. The module is RoHS compliant and carries CE and FCC certifications, and is compatible with Fortinet QSFP28 ports such as those accepting the FN-TRAN-QSFP28-SR form factor.
Advantages
The module provides a standardized QSFP28 electrical and mechanical interface for easy hot-plug installation in compatible network equipment. With support for 100000 Mbit/s data rates over multimode fiber and an MPO/MTP optical connection, it enables high-density, short-reach interconnects in data center and enterprise networks. Compliance with CE, FCC and RoHS standards ensures adherence to regulatory and environmental requirements.
Suitable for
100G Ethernet links in data center aggregation and spine-leaf topologies
High-speed uplinks between switches and routers supporting QSFP28
Short-reach multimode fiber connections (MPO/MTP-based patching)
Hardware platforms compatible with Fortinet QSFP28 SR modules
Key specifications
Interface type: QSFP28
Maximum data transfer rate: 100000 Mbit/s (100 Gbit/s)
Optical connector style: MPO/MTP (multimode MPO trunking)
Intended fiber type: multimode fiber
Product colour: Nickel
Weight: 0.04 kg
Compliance: RoHS, CE, FCC
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on your switch, router or other network device while the host is powered according to the equipment vendor guidelines for hot-plug transceivers. Connect an MPO/MTP multimode patch or trunk cable between transceivers or to a patch panel, ensuring correct fiber polarity and that the receiving equipment supports the SR multimode profile. Verify link and data rate through the host device management interface and confirm Digital Diagnostics Monitoring (DDM/DOM) availability if supported by the host.
Usage recommendations
Use multimode MPO/MTP patch cords designed for 100GBASE-SR4 deployments and follow your hardware vendor’s compatibility list. Keep transceiver dust caps on when not in use and observe ESD precautions during handling. Verify that the host device supports the specific QSFP28 SR profile for full functionality.
