EnGenius SFP2185-05 sieťový transceiver modul 1,25 G multimódové optické vlákno 850 nm 0,5 km

The EnGenius SFP2185-05 network transceiver module is a hot-pluggable Gigabit Ethernet SFP designed for short-distance multimode fiber links. It operates at 1.25G (1250 Mbit/s) with an 850 nm wavelength and supports up to 0.5 km reach over multimode fiber. The module uses an LC duplex fiber connector, complies with IEEE 802.3z, meets industry standards for SFP modules and is RoHS compliant. It is a compact, low-power device suitable for linking SFP ports and slots in network switches and equipment.

Advantages

The transceiver offers hot-pluggable installation, low power dissipation and compliance with international safety standards as a Class 1 laser product (IEC 825). Its industry-standard SFP form factor and LC duplex connector ensure interoperability with compatible network hardware. Compact dimensions and modest voltage/current requirements make it suitable for dense installations and typical enterprise or service-provider equipment.

Suitable for

• Short-reach multimode fiber links in LAN environments
• Connecting SFP ports on switches, routers and media converters
• Data center uplinks and server-to-switch connections within 0.5 km
• Replacing or upgrading existing 1.25G SFP modules

How to use

Ensure compatible SFP ports and that connected fiber cable and transceiver specifications match (multimode fiber, LC duplex). With the host device powered on or off according to vendor guidance, insert the SFP module into the SFP slot until it engages. Connect LC duplex fiber patch cables to the module, observing correct transmit/receive orientation. Verify link and negotiate speed on the network device. To remove, follow hot-swap procedures recommended by the equipment manufacturer.

Recommendations

Use the module with multimode fiber and LC duplex patch cables rated for 850 nm operation. Avoid exposing the optical interfaces to dust; keep protective caps on when not in use. Confirm compatibility with the host device firmware or vendor compatibility lists to ensure proper operation.
