Custom 40G QSFP+ Parallel SMF Module, MPO Breakout Routing
-
Advanced Single-Mode Breakouts: Designed specifically for complex breakout applications. Unlike standard LC models, this specialized series utilizes an MPO/MTP connector strictly on Single-Mode Fiber (SMF).
-
Massive Port Density: Allows for seamless 40G optical splitting into four independent 10G streams, exponentially increasing your core switch port density for massive server farm deployments.
-
Bespoke Distance Configurations: Available in exact factory configurations tailored to your specific reach requirements, supporting short inter-rack links to extended campus-wide parallel runs.
-
Precision Optical Alignment: Terminating single-mode glass into an MPO array requires extreme precision. Our manufacturing cleanrooms ensure zero-defect geometric compliance across all lanes.
Product Overview
When hyper-cloud operators need to connect a high-capacity 40G core switch directly to four separate 10G single-mode servers, standard duplex optics cannot do the job. The Wolon Custom 40G QSFP+ Parallel SMF Module series is explicitly built for this complex task. By incorporating an MTP/MPO receptacle equipped with powerful single-mode lasers, these modules act as the perfect origin point for breakout cables. We custom-tune these parallel modules to match your facility's exact single-mode fiber attenuation, delivering flawless, unamplified data streams across your custom infrastructure.

Frequently Asked Questions
Q: Why does a single-mode module use an MPO connector instead of an LC connector?
A: This is a parallel single-mode design (PSM4 style). It uses four separate 1310nm lasers. It is specifically designed so you can use an MPO-to-LC single-mode breakout cable to connect one 40G port to four individual 10G LR ports.
Q: Can it connect to a standard 40GBASE-LR4 module?
A: No. Standard LR4 uses an LC connector and CWDM multiplexing. This parallel module uses an MPO connector. They are physically and technologically incompatible.
Q: Are 10km and 20km MPO versions standard?
A: The 2km (IR4) is standard, but the 10km (eSM4) and 20km lengths are custom factory builds. We manufacture these specifically for clients who need long-distance 4x10G breakout capabilities without using additional transport equipment.
