SFP Optical Transceiver 1550nm


80km Single Mode Fiber Transceiver

Product Description

Cisco Compatible 1000BASE-ZX 1550nm SMF 80km SFP Duplex LC Optical Transceiver





The GIGAOPTO's GTS-L1512-80DC transceiver is a small form factor module that provides 1000Base-ZX throughput up to 80km over single-mode fiber (SMF) using a wavelength of 1550nm via an LC connector. This transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. The transmitter section uses a multiple quantum well 1550nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The transceiver is compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
