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.

icrolight is a high-tech enterprise specializing in the R&D, manufacturing and sales of active and passive photonic devices for microwave photonics, LiDAR ranging, gas sensing, fiber optics and photomedicine.
Against the evolving demands for military‑grade hardware, rail transit equipment and heavy‑duty machinery that run under high‑shock vibrating conditions, anti‑loose connectors serve as indispensable hardware for stable power delivery and high‑speed signal transmission.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
For pulsed laser and full-spectrum optical testing, photodiodes and thermopiles have inherent drawbacks. Photodiodes show weak response in infrared band, while thermopiles feature slow response and cannot capture nanosecond narrow pulses.
