Módulo transceptor de red TELTONIKA PR4DU22K SFP fibra óptica 1250 Mbit/s 850 nm carcasa de metal gris

Teltonika PR4DU22K is an SFP fiber optic transceiver module designed for short-range multimode links. It supports a maximum data rate of 1250 Mbit/s and operates at an 850 nm wavelength. The module is enclosed in a compact metal grey housing and fits standard SFP slots on compatible switches, routers and other network devices. Manufactured to meet REACH and RoHS environmental standards, it is supplied as a single unit for straightforward replacement or spare inventory.

Advantages

The transceiver provides a compact SFP form factor that simplifies installation and replacement in existing network hardware. Its 1250 Mbit/s capability and 850 nm multimode operation make it suitable for common short-distance fiber runs within buildings or campus environments. The metal housing offers reliable physical protection and helps with heat dissipation, while conformity to REACH and RoHS indicates compliance with applicable material and safety restrictions.

Suitable for

• Short-range multimode fiber links inside data centers, office buildings or campuses
• Upgrading or replacing SFP ports on switches and routers
• Network spares for maintenance and rapid hardware swaps

Key specifications

• Interface type: SFP
• Maximum data transfer rate: 1250 Mbit/s
• Wavelength: 850 nm (multimode)
• Housing: metal, grey
• Form factor: hot-pluggable SFP module

How to use

Insert the SFP module into the SFP slot of a compatible switch, router or media converter while the device is powered down or following the manufacturer's hot-swap guidance. Connect an appropriate multimode fiber patch cable to the transceiver's optical port, ensuring correct connector type and proper cleaning of end faces. Verify link status and data rate on the network device's management interface and monitor for stable operation.

Recommendations

Use multimode fiber optimized for 850 nm operation and short-distance links. Clean connector end faces before insertion and follow electrostatic discharge (ESD) precautions when handling the module. Keep spare modules in their protective packaging until use to prevent contamination or physical damage.
