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
