WDM Filter
The WDM filter is the core component of wavelength division multiplexing systems. Its function is similar to the "traffic controller" in high-speed fiber optic networks, combining and separating optical signals according to wavelength differences. Through the optical interference principle of specific dielectric films, it precisely multiplexes optical signals of different wavelengths (such as 1310nm, 1490nm, 1550nm, etc.) into one fiber for transmission, or demultiplexes them into independent channels at the receiving end, thereby achieving simultaneous transmission of multiple signals on a single fiber and greatly improving the communication capacity and transmission efficiency of optical fibers.

10G SFP LR CWDM(10Km) OSFP-10CWDM10
Wavelength-Division Multiplexing (WDM)
O-send
Emission wavelength [CW]: DM Specification: 10Km
This enhanced small-form-factor pluggable (SFP) fiber transceiver includes digital diagnostic monitoring (DDM). It complies with Ethernet standards and is ideal for 10Gbps data communications. DDM alarms and warnings are integrated through an I2C serial interface under the SFF-8472 multisource agreement (MSA), version 10.4. The transceiver supports data rates from 155Mbps to 1.25Gbps and provides a solution for 1310nm transmission over up to 20 kilometers of single-mode fiber. Subwatt consumption and excellent EMI performance support high port density. It is RoHS compliant and designed and tested to industry safety standards, and is a Class I laser product under US FDA/CDRH and international IEC-60825 standards. The SFP LR connects to a standard 20-contact SFP connector for hot swapping, allowing configuration changes or maintenance by replacing the transceiver without switching off the host. Transmitter and receiver DATA interfaces are internally AC-coupled. An LV-TTL transmitter-disable input and loss-of-signal (LOS) output are also provided. A bail latch permits easy module removal and complies with the SFP MSA. A single +3.3V supply powers operation at case temperatures of 0°C to +70°C commercially or -40°C to +85°C industrially. The metal case protects against electromagnetic interference.
