12G-SDI CWDM SFP+ Transceiver 10km 4K/8K Video DDM Optical Module LC Connector

SFP Fiber Transceivers 12G-SDI CWDM 10km Digital Video SFP Optical Module

SFP Optical Transceivers Overview

The E-link 12G-SDI CWDM SFP+ optical transceiver series represents a cutting-edge fiber optic solution engineered for next-generation ultra-high-definition video systems. These high-performance, cost-effective transceiver modules support robust 12Gbps data transmission with 10km reach over single-mode fiber, making them ideal for 4K broadcast and production environments.

Designed with an advanced three-section architecture, each module incorporates an un-cooled CWDM DFB laser transmitter, high-sensitivity PIN photodiode with trans-impedance preamplifier, and intelligent MCU control unit. This sophisticated integration ensures exceptional signal integrity and reliable performance across the entire 1270nm to 1610nm CWDM wavelength spectrum.

Fully compliant with SFP Multi-Source Agreement (MSA) standards, these transceivers feature comprehensive SFF-8472 digital diagnostics monitoring (DDM) capabilities, enabling real-time performance tracking and system management. The modules meet stringent Class I laser safety requirements per international standards, ensuring safe operation in various professional video applications.

These transceivers are particularly valuable for bandwidth-intensive applications including 4K studio production, live event broadcasting, and high-resolution medical imaging systems. Their CWDM technology enables efficient fiber infrastructure utilization, allowing multiple 12G-SDI signals to be transmitted over a single fiber strand while maintaining broadcast-grade signal quality and transmission reliability.
