## Long description

Lightwin 1.25 Gbit SFP fiber transceiver for Aruba-compatible equipment. This multimode 850 nm module with LC-duplex connector supports a 1.25 Gbit/s data rate and offers digital diagnostic monitoring (DDM). It operates from a single 3.3 V supply and provides a maximum reach of up to 550 m over 50/125 µm multimode fiber, making it suitable for short-range network links and switch-to-switch or switch-to-access point connections.
Advantages
The transceiver uses an 850 nm VCSEL transmitter and a PIN photodetector to deliver reliable multimode performance. It supports digital diagnostics for in-service monitoring of optical parameters and is designed with low EMI and robust ESD protection. The SFP form factor with LC duplex connector ensures broad compatibility with Aruba-compatible ports and simplifies installation in existing SFP slots.
Suitable for
Short-range Ethernet links within campus or building networks
Connections between switches, access points and network aggregation devices
Multimode fiber segments using LC-duplex connectors (50/125 µm MMF)
When it may not be suitable
This module is intended for multimode fiber and short-reach applications; it is not suitable for single-mode long-distance links or runs beyond the specified 550 m range. It also requires SFP ports that support 1.25 Gbit/s modules and may be incompatible with devices that enforce proprietary transceiver authentication if they do not accept third-party modules.
Key specifications
Data rate: 1.25 Gbit/s (1250 Mbit/s)
Wavelength: 850 nm (VCSEL)
Maximum reach: up to 550 m on 50/125 µm multimode fiber
Connector: LC duplex
Power supply: +3.3 V single-supply operation
Diagnostics: Digital Diagnostic Monitoring (DDM) compliant
Transmitter/receiver type: VCSEL transmitter and PIN photodetector
Interfaces: LVPECL compatible data input/output
Standards: IEC-60825 laser safety compliant; RoHS compatible
How to use
Install the SFP module into a compatible SFP port on the switch or network device while the device is powered according to the manufacturer's guidance. Connect LC-duplex multimode fiber patch cables (50/125 µm) between devices, ensuring correct transmit/receive orientation. Monitor link status and diagnostics via the host device's management interface to verify optical power, temperature and other DDM parameters. Follow safe handling procedures for optical transceivers and avoid direct exposure to the laser output.
What to consider before purchase
Ensure the target device accepts third-party SFP modules or is Aruba-compatible.
Confirm the fiber type and connector (50/125 µm MMF with LC duplex) match the planned cabling.
Verify the required maximum reach does not exceed 550 m for your link.
Check device support for 1.25 Gbit/s SFP modules and DDM monitoring if needed.
Usage recommendations
Use the module for short multimode links within buildings or campus environments. Keep patch cable lengths and connections clean, use appropriate fiber adapters where needed, and monitor DDM values to detect signal degradation early.
