6ch LC duplex QSFP Receiver ROSA (4ch x 6Gbps) + μ-bosa (2.5Gbps) (2km) FVQ2-4R1B-SM2 Product Features Video-dedicated transceiver Hot-pluggable QSFP+ form factor One LR4 ROSA and μ-bosa inside package - 4ch x 6Gbps PIN detectors with TIA in TO - 2.5Gbps μ-bosa (1550nm Tx/1310nm Rx) Up to 2km on SMF Power dissipation < 4.0 W Duplex LC Connector Single +3.3V Power Supply Commercial temperature range -10 C to 70 C Built-in digital diagnostic functions RoHS-6 Compliant (Lead-free) Application Note 4K60Hz (4:4:4) video signal transmission Product Descriptions FVQ2-4R1B-SM2, the QSFP+ optical transceiver from FOTTU, is a high performance and cost-effective solution to optically de-multiplex 4K60Hz video signals. It provides four backward channels for receiving and de-multiplexing video signals and two channels (one forward and one backward) for data signal transmission. For video signals, this transceiver uses one ROSA, composed of four channels of PIN detector with TIA and thin film filter for different wavelengths to optically de-multiplex video signals transmitted via a single fiber. Each channel supports up to 6Gbps at 2km. For data signals, this transceiver uses a μ-bosa to send and receive data signals via a single fiber, and supports up to 2.5Gbps. By adopting the standard QSFP+ LC dual core package with pin configuration adjusted for video signals, FVQ2-4R1B-SM2 is a highly reliable solution optimized for 4K60Hz applications FOTTU CO., LTD Rev 2016/5/31 page1
EMC Most equipment utilizing high-speed transceivers are required to meet the following requirements: 1) FCC in the United States 2) CENELEC EN55022 (CISPR 22) in Europe To assist customers for managing the overall equipment EMC performance, our transceivers have been designed to satisfy FCC class B limits and provide good immunity to radio-frequency electromagnetic fields. Eye Safety This laser-based single mode transceiver is a Class 1 laser product. It complies with IEC 60825-1 Ed.2: 2007 and FDA performance standards for laser products (21 CFR 1040.10 and 1040.11) except for deviations pursuant to Laser Notice 50, dated June 24, 2007.
