1x2 Coupler Optical Optional SC-APC

 

 

• Low Noise & Low Threshold Current: With a relative intensity noise (RIN) of ≤-130dB/Hz and threshold current (Ith) of 3-15mA (CW, max 50mA at 85℃), the coupler ensures accurate data transmission for precision laser sensors (e.g., industrial distance measurement) and minimizes energy consumption in large-scale optical networks (e.g., FTTH).
• Enhanced Signal Stability: Integrated optical isolator provides ≥30dB optical isolation (ISO), preventing signal interference in 5G base stations and data center interconnections-critical for 24/7 network uptime demanded by telecom operators.
• High Reliability for Bulk Deployment: Laser-welded construction and coaxial pigtail packaging ensure long lifespan and resistance to vibration. This reduces maintenance frequency for buyers deploying thousands of units (e.g., FTTH fiber networks).
• Real-Time Performance Tracking: Built-in InGaAs/PIN monitor (monitor current Im: 100-1000μA, CW at If=Ith+20mA) allows buyers to conduct batch quality checks efficiently, ensuring consistency across 1000+ piece orders.
• Wide Temperature Adaptability: Operating temperature range of -20~+70℃ (storage temp: -40~+85℃) makes it suitable for outdoor 5G base stations and industrial workshops-no need for additional temperature control equipment.

 

 

• Fiber-to-the-Home (FTTH) Networks: Insertion loss (IL) of 6.7-7.2dB minimizes signal attenuation over long distances, reducing the need for signal repeaters.
• 5G Base Station Interconnections: 2.5GHz bandwidth (-3dB) and rise/fall time (20-80%) of ≤120ps support high-speed data transmission between 5G towers.

• Data Center Interconnections: Low capacitance (10-15pF, VRD=5V, f=1MHz) and fast switching performance ensure seamless connectivity between servers-ideal for data centers scaling to 1000+ rack deployments.

 

• Industrial Distance Measurement: Spectral width (Δλ) of 0.3-0.5nm (CW at If=Ith+20mA) ensures precise light beam control, while low distortion avoids measurement errors in automated production lines.

• Precision Detection Systems: Side mode suppression ratio (SMSR) of ≥30dB eliminates spurious signals, making it a top choice for medical device manufacturers and semiconductor inspection equipment buyers.
