Building-to-building and campus backbone runs measured in kilometers sit squarely in this module's territory: the DZS-40G-LR4 pushes 40G across up to 10km of single-mode fiber at 1310nm, terminating in a duplex LC connector on DZS/Zhone platforms. It arrives coded for the DZS/Zhone host and is treated as a known part from the moment it seats.

LR4 is the operative protocol designator here, and DDM/DOM diagnostics keep the module's optical condition visible to the host while it runs. Assembly and behavior are validated against MSA requirements one unit at a time, with EEPROM and cleanliness checks alongside. TenFourOptics covers it under the GreenLights4Life® Limited Lifetime Replacement Warranty. It is a stocked item and ships same or next business day.
