Compatibility: Documented OEM compatibility (Juniper published compatibility documentation): this module is accepted in 40G QSFP+ ports on the EX3400 Series, EX4600 Series, EX4650 Series, PTX10000 Series, QFX10000 Series, QFX5100 Series, and QFX5120 Series. This module follows Juniper's published compatibility matrix; for your exact line card or OS release, email 10.4@tenfouroptics.com and we'll confirm fit.
Works with: 4× 10G LR (SMF) optics at the far end — this module runs 40G as four 10G lanes in breakout mode.
Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.
At single-mode reach this module bridges the middle ground — access to aggregation, building-to-building campus links, and short data-center interconnect spans that outrun multimode but never need amplification. The single-mode path keeps the signal clean across the full distance over existing OS1 and OS2 plant. It operates 10km.
Coded to the host EEPROM, it comes up as a genuine module: full diagnostic visibility, no compatibility warnings, and side-by-side operation with optics already in the chassis.
We program each module to the Juniper host EEPROM and run it through traffic, DOM, and optical-cleanliness checks before it ships. Class 1 laser certified and RoHS compliant.
Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty. In stock and ships same or next business day.
