## Summary description

The BlueOptics S28-10G-25G-SR-85C-BO is a fiber optic SFP28 transceiver module designed for high-speed data transmission. It features an LC connector and is made from durable aluminum, weighing only 20g. This module is ideal for network applications requiring reliable and efficient connectivity.

## Long description

The BlueOptics S28-10G-25G-SR-85C-BO SFP28 LC Aluminium 20g is a fiber optic transceiver module designed for high-speed short-reach multimode links. It uses an SFP28 interface and LC duplex connector, is constructed with an aluminium housing for mechanical durability, and weighs approximately 20 g. The module supports optical transmission with 850 nm wavelength components suitable for 10G and 25GBASE-SR applications over multimode fiber and is compatible with systems that accept MSA-compliant SFP28 modules.
Advantages
The module delivers compact SFP28 form factor compatibility with both 10G and 25GBASE-SR protocols, enabling flexibility in mixed-speed environments. An aluminium housing provides robust physical protection while keeping the module lightweight. Built according to MSA guidelines, it is suitable for use in hardware platforms that require standard SFP28 optics and supports digital diagnostics for remote monitoring when the host supports DDM/DOM.

 Equipment requiring SFP28 LC optical transceivers with MSA compatibility
Key specifications
 Interface type: SFP28
 Connector: LC duplex
 Wavelength: 850 nm (multimode)
 Supported speeds: 10G and 25G (BASE-SR)
 Housing material: aluminium
 Weight: approximately 20 g
 Form factor: SFP28, MSA compliant
 Digital diagnostics: supported (requires host support for DDM/DOM)
How to use
Install the transceiver into an SFP28 port on a compatible switch, router or other network device following the device manufacturer’s instructions. Use LC duplex multimode fiber patch cords (OM3/OM4 recommended for 25G distances) to connect between transceivers or to patch panels. Ensure the host device supports the desired speed (10G or 25G) and, if you intend to monitor optical parameters, confirm that the hardware exposes DDM/DOM information. Handle the transceiver by the housing and avoid touching the fiber endfaces; keep dust caps on when not connected and clean connectors with appropriate fiber cleaning tools before insertion.
Рекомендации по использованию
For predictable short-reach performance at 25G, use quality multimode fiber (OM4 or better) and keep patch cord lengths within the recommended range for BASE-SR optics. Verify compatibility with your equipment vendor and, where available, enable digital diagnostics to monitor power, temperature and other operational parameters for proactive maintenance.
