The GPON OLT SFP transceiver provides up to 2.5G-TX/1.25G-RX up to 20km over single-mode fiber (SMF) using a wavelength of 1490nm-TX/1310nm-RX via an SC connector. It can operate at temperatures between 0°C and 70°C. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. It is fully compliant with ITU-T G.984.2 and RoHS standards and is ideal for GPON system and FTTx applications.
