Cleerline™ Single Mode Bi-Directional SFP
Bi-directional (BiDi) SFP transceivers are high performance, cost effective modules supporting dual data-rates of 1.25Gbps/1.0625Gbps and 20km transmission distance with SMF. These SFPs use Wavelength Division (WDM) technology, mixing two wavelengths simultaneously.

These modules each accept 1 LC connector.

The SSF-SFP-SM1GBDA consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. 

The SSF-SFP-SM1GBDB transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. 

All modules satisfy class I laser safety requirements.

The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA. Note: not compatible with HP
Product Pairing - In order to function correctly, these SFPs must be used as a pair CN-SSF-SFP-SM1GBDA, matched with CN-SSF-SFP-SM1GBDB
