How to choose 40G QSFP+ optical module？

40G QSFP+ optical module refers to the transmission rate of 40G, and the package of this optical module is QSFP+. 40G optical module has four independent full-duplex transceiver channels, each channel of the transceiver rate of 10G, thus forming a 40G transmission rate, ETU LINK Optical Communication (ETU-LINK) will introduce the 40G QSFP + optical module what types are there.

IEEE organization for 40G QSFP + optical module to develop a variety of transmission protocols, common are: 40G BASE-SR4, 40G BASE-LR4, 40G BASE-BiDi, 40G BASE-ER4, etc., the interface type of these optical modules, transmission distance, working wavelength are not the same, the following is the parameter list of 40G optical modules for you reference.

ETU PN	Data Rate	Package	Wavelength (nm)	Distance	Connector	Patch cord
EQP854X-01D	40G	QSFP+	850	150m	MPO	OM4
EQP854X-04D	40G	QSFP+	850	400m	MPO	OM4
EQP314X-2D-M	40G	QSFP+	1310	2km	MPO	OS2
EQP274X-10D	40G	QSFP+	CWDM	10km	Dual LC	OS2
EQP274X-40D	40G	QSFP+	CWDM	40km	Dual LC	OS2

As shown in the table above, 40G SR4, 40G ER4 and 40G BIDI are multimode optical modules that require the use of OM3/OM4 fiber optic patch cords for transmission, which are suitable for equipment interconnection within the data center due to the short transmission distance; 40G SR4, 40G eSR4 and 40G PSM4 interface types are MPO interfaces, this type of interface can not only achieve 40G link connection, but also use MPO-LC patch cord to achieve 40G link and 10G link connection; LX4, LR4, ER4 interface type is LC, need to be used with single-mode fiber OS2 patch cord, the transmission distance is more than 2KM, the farthest is 40KM.

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
