Arista Networks Qsfp-40g-Er4 Compatible Qsfp+ 40g Er4 1310nm 40km Dom Duplex LC/Upc SMF Fiber Transceiver
The 40G QSFP+ ER4 module is designed for use in 40GBASE Ethernet throughput up to 40 km over single-mode fiber (SMF) using a wavelength of 1310 nm via duplex LC connectors. This transceiver is compliant with QSFP+ MSA, IEEE 802.3bm 40GBASE-ER4, and the OTU3 standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters. With these features, this easy-to-install, hot-swappable transceiver is suitable to be used in various applications, such as data centers, high-performance computing networks, and enterprise core and distribution layer applications.

Q: Do you support customization?
A: Definitely yes; customization is available according to your product requirements.
Q: Can I get a sample first?
A: We do offer samples before making any production so that the production is up to the buyer's expectations. Samples can be delivered within 5-8 days.
Q: What is your MOQ?
A: 1 piece is available. We can also provide free samples for our valued customers.
Q: What's the max real distance I can cover with this module?
A: Hello, the theoretical environment is 40 km. The actual environment needs to be calculated based on the actual link loss.
Q: Hello, I need to use 40 km 40G ER4 for a transmission distance of 20 km. Do I need to add an attenuator?
A: Hello, the actual link is 20 km without adding attenuation.
