Custom 40G QSFP+ LR4 Module, Tailored Extended Single-Mode

Product Overview

The Wolon Custom 40G QSFP+ LR4 Module series provides the ultimate flexible backbone. Unlike standard single-mode equipment that relies on complex internal multiplexers, the Parallel SMF module utilizes pure physical layer isolation. It injects four 10Gbps 1310nm optical beams directly into separate cores of an MPO trunk cable. This "dedicated lane" approach completely removes the latency and optical loss generated by MUX components, making it the ultimate weapon for single-mode, high-density breakout splitting at edge computing nodes.

Frequently Asked Questions

Q: Standard LR4 is rated for 10km. How does this reach 30km?
A: We use a higher output DFB laser and a more sensitive PIN receiver combination than what is found in standard 10km LR4 modules, giving you a larger optical power budget.

Q: Do I need to use an optical attenuator during testing?
A: If you are testing this 30km module on a short fiber patch cord (under 2km) in the lab, yes. You should add a 3dB to 5dB attenuator to avoid overloading the receiver.

Q: Is the wavelength grid the same as standard LR4?
A: Yes, it uses the exact same 4-lane CWDM grid (1271, 1291, 1311, 1331nm) as standard LR4, just with higher transmit power.
