Ürün Detayları
1310nm 1.25Gbps 20km 0ºC ~ +70ºC DDM,Single-mode Duplex lc SFP Module Fiber Optic Transceiver
Product Description
1.25gbps 1310nm Sm Duplex Lc 20km Fiber Optic Sfp Module
Description of 1.25g sfp module
The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 20km transmission distance with SMF.
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.
The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
