3Gbps Video SFP Optical Transceiver, 40km Reach                                                                                                                                            

 

Applications

SMPTE 297-2006 Compatible Electrical-to-Optical Interfaces.

HDTV/SDTV Service Interfaces.

 

Description

The video series transceivers are high performance, cost effective modules for duplex video transmission application over single mode fiber.

The transceiver is designed to transmit/receive data rates from 50Mbps to 2.97Gbps and is specifically designed for robust performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates. The module is fully compliant with SMPTE 297M-2006.

The 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.

Notes: 1. The optical power is launched into SMF.

2. Rise and fall times, 20% to 80%, are measured following a fourth-order Bessel-Thompson filter with a bandwidth of 0.75 x lock frequency corresponding to the serial data rate

3. PECL input, internally AC-coupled and terminated.

4. Internally AC-coupled
