Product Description

Class B+ ONU for GPON

Single Fiber Bi-Directional WDM Transceiver

1.244Gbps Upstream and 2.488Gbps Downstream

100% Full Compatible with Mainstream Host Devices





This GTF-SGU12-20DC GPON ONU Class B+ SFF 2x10 SCUPC Receptacle transceiver module is designed for low cost P2MP (point to multi-point) FTTx applications. It can fully support the Class B+ ODN application specified by the ITU-T G.984.2 standard and ITU-T G.984.2 Amendent-2006.

This GPON ONU B+ transceiver is packaged of small form factor 2x10 with a SC UPC receptacle connector.

The GPON ONU SFP module consists of 1310nm un-cooled DFB Laser, InGaAs preamplifier and a WDM filter in a high-integrated optical sub-assembly. It transmits 1.244Gbps at 1310nm in burst-mode and receives 2.488Gbps at 1490nm in continuous-mode. This transceiver is Class 1 laser product that complies with the IEC 60825-1 and IEC 60825-2, and it is ROHS-6 compliant.

The metallic package guarantees excellent EMI and EMC characteristics, which totally complies with international relevant standards.

Digital diagnostics functions are available, as specified in SFF-8472,which provides real-time monitoring of the transceiver temperature, laser bias current, optical power, received optical power and transceiver supply voltage.
