10G SFP+ Copper-T RJ45 30m Transceiver

Transmission data rate up to 11.3Gbps per channel QSFP+ MSA compliant Up to 80km reach over standard single mode fiber Hot pluggable electrical interface Operating case temperature 0°C to +70°C 3.3V power supply RoHS 6 compliant（lead free） FAQ: Q1: What is a 40G QSFP Optical Module?‌ A1: A 40G QSFP (Quad Small Form-factor Pluggable) module is a hot-swappable transceiver that supports 40Gbps data transmission. It uses a 4-channel parallel design and is widely deployed in data centers and high-performance computing networks. Q2: What are the common types of 40G QSFP modules?‌ A2: QSFP+ SR4 (850nm multimode, 100m) QSFP+ LR4 (1310nm single-mode, 10km) QSFP+ ER4 (1310nm single-mode, 40km) QSFP+ BiDi (Single-Fiber Bidirectional) Q3: How do I check if a 40G QSFP module is compatible with my device?‌ A3: Verify three aspects: Switch vendor compatibility lists Matching fiber type (MMF/SMF) Required transmission distance Q4: How to resolve overheating in 40G QSFP modules?‌ A4: Solutions: Ensure adequate device ventilation Use modules with heat dissipation fins Avoid sustained 100% bandwidth utilization Q5: What precautions should I take when installing 40G QSFP modules?‌ A5: Key operational guidelines‌: Clean fiber connectors‌ before insertion to prevent dust from disrupting optical signal transmission. Ensure ‌adequate ventilation‌ around devices; reserve thermal headroom for high-heat modules. Configure ‌port aggregation mode‌ on the switch when using breakout applications. Q6: What's the difference between SFP, QSFP and QSFP-DD modules?‌ A6: SFP (1-25G), QSFP (40-100G), and QSFP-DD (400G+) differ in form factor and bandwidth capacity. QSFP-DD doubles QSFP28's density with 8-lane electrical interfaces. Q7: How does ETU-Link ensure compatibility with major brands?‌ A7: We maintain a multi-vendor test lab with full protocol support (Ethernet/InfiniBand/Fibre Channel) and 100% compatibility verification before shipment Q8: What temperature ranges do your modules support?‌ A8: Commercial grade (0°C to +70°C) Extended grade (-20°C to +85°C) Industrial grade (-40°C to +85°C) for harsh environments. Q9: How does ETU-Link achieve 40G QSFP+ interoperability?‌ A9: Through: Multi-vendor switch testing Firmware customization for legacy equipment MSA-compliant electrical interfaces Q10: Do 40G QSFP+ modules support DDM/DOM monitoring?‌ A10: Standard feature including: Real-time temperature (±1°C accuracy) Tx/Rx power (µW/dBm display) Laser bias current
