Product catalog summary
Product Overview
The TSSP-8525G-SR is an 850nm SFP+ multi-mode optical transceiver with diagnostic monitoring capabilities. It supports a 25.78Gb/s bit rate and is RoHS 6 compliant, ensuring it is lead-free.

Features
  • Supports 25.78Gb/s bit rate.
  • Utilizes 850nm VCSEL laser and PIN photo-detector.
  • Maximum link length of 70m on OM3 MMF and 100m on OM4 MMF.
  • Includes digital diagnostics via I2C interface.
  • Operates within a temperature range of 0°C to +70°C.
  • Consumes less than 1W of power.
  • RoHS compliant with password protection for A0h and A2h.

Applications
  • 25GBASE-SR Ethernet.
  • 32G Fiber Channel.
  • Other optical links.

Absolute Maximum Ratings
These ratings indicate the damage threshold of the module. Exceeding these can cause immediate damage.
  • Power Supply Voltage: 0 to +3.6 V.
  • Storage Temperature: -40 to +85°C.
  • Operating Case Temperature: 0 to +70°C.
  • Relative Humidity: 5 to 95%.
  • RX Input Average Power: Max 0 dBm.

Recommended Operating Environment
  • Power Supply Voltage: 3.135 to 3.465 V.
  • Operating Case Temperature: 0 to 70°C.

Optical Characteristics
  • Transmitter Center Wavelength: 820 to 880 nm.
  • RMS Spectral Width: Max 0.6 nm.
  • Average Optical Power: -5.0 to 2.4 dBm.
