研華SFP-GS4-70KRX Hardened SFP/1250-ED, SSLX-SM/SC (1550XMT/1490RCV) 70km (also known as 808-38290)

• Industrial standard small form-factor pluggable (SFP) package
• Provides digital diagnostics monitoring (DDM) functionality
• Wide specifications and fiber types available
• Comes with metal enclosure for EMI
• The Class 1 laser product complies with EN 60825-1
• Supports plug-n-play operation
• Advantech's small form-factor pluggable (SFP) transceiver family is available with a variety types of copper SFP and fiber SFPs, SFP and XFP. This transceiver module is compliant with the small form-factor pluggable (SFP) multi-source agreement (MSA). They are versatile and widely used because of their hot-pluggable feature, and being easy for exchange for optical type and reach and field replaceability. Lots of Advantech's SFPs provide robust industrial performance with extended operating temperature range. Meanwhile, through real-time monitoring, the DDM (digital diagnostic monitoring) functionality provides users critical information such as receive optical power, transmitted optical power, laser bias current, input voltage and temperature in the network. This approach is definitely a better fault isolation and error detection method.
