Product / Model
DIGISOL DG‑SA3131 – a 25 GBASE‑LR SFP28 optical transceiver module.Standard / Data Rate
Supports 25GBASE‑LR specification; designed for 25 Gbps Ethernet. Bit rate specified around 25.78 Gb/s.Transmission Distance / Reach
Capacity to transmit up to 10 km over single‑mode fiber (SMF).Wavelength
Operates at 1310 nm, which is typical for long‑range single‑mode LR optics.Laser & Receiver Type
Uses a DFB (Distributed Feedback) laser transmitter and a PIN receiver.Optical Connector
Features a duplex LC connector.Electrical Interface
Uses a high‑speed I/O electrical interface, specified as 25GAUI.Form Factor / Package
SFP28 MSA‑compliant package (which is essentially the same form factor as SFP, but capable of higher data rates).Power Supply / Consumption
Runs from single +3.3 V supply. Maximum power consumption is approx 1.5 W.Digital Diagnostic Monitoring (DDM)
Has integrated diagnostic monitoring via I²C interface — so you can monitor parameters like temperature, optical power, voltage etc.Operating Temperature
Case / operational temperature range: 0 °C to +70 °C (standard commercial temperature range).Storage Conditions
Can be stored in −40 °C to +85 °C.
