Product Description

Cisco Compatible 1000BASE-LX/LH SFP Transceiver Module (550M@MMF / 10km@SMF 1310nm LC Industrial DOM)





The GIGAOPTO's GTS-L1312-10DI transceiver is a high performance, cost-effective module supporting dual data-rate of 1.25Gbps/1.0625Gbps and 10km transmission distance with SMF and 550m with MMF using a wavelength of 1310nm via an LC connector. The industrial SFP transceiver module provides a reliable rugged connectivity solution over fiber for system integrator, distributors and ends users in industrial network infrastructure and fiber cabling.


The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.


This 1.25G SFP transceiver module fully complies with the SFP Multi-Source Agreement (MSA) and can be used on MSA compliant SFP ports of optical networking equipment.
