Customized MT-Jumper for 100G/200G High-Speed Transceiver - China Suppliers and Factory Solutions
Product Introduction: MT-jumper
MT-jumper (MT Connector Jumper) is a high-precision, short-reach optical interconnect component specifically designed for internal or external connections in optical modules, enabling low-loss parallel signal transmission.
As a compact optical jumper pre-terminated with MT (Mechanical Transfer) industry-standard high-density interfaces at both ends, its primary function is to establish reliable parallel optical links within optical modules (e.g., connecting laser arrays, photodetectors, or AWG chips to module ports) or between modules and external fiber arrays. It optimizes space and ensures alignment accuracy for high-speed applications.
Key Design & Structural Components
MT Connectors
Rectangular ferrule (typically ceramic zirconia or LCP plastic) with precision-machined V-grooves. Equipped with two guide pins for self-alignment, ensuring micron-level core positioning. Available in male/female configurations.
Optical Fibers
Bundled in a linear array, compatible with multimode (OM3/OM4/OM5, 50/125 μm or 62.5/125 μm) and single-mode (OS1/OS2, 9/125 μm) fibers. Available in 12, 24, or 48-fiber counts.
Cable Structure
Short-length cable (typically 10–50 mm) with a thin, flexible jacket (PVC or LSZH) for easy routing, reinforced with aramid yarn or glass fiber to resist tensile stress and bending.
End-Face Treatment
Polished to UPC (return loss >45 dB multimode / >55 dB single-mode) or APC (return loss >60 dB single-mode) standards for optimized physical contact and low reflection.
Critical Performance Traits
- Low Insertion Loss: Typical insertion loss <0.3 dB per channel (multimode) and <0.5 dB per channel (single-mode), with channel-to-channel uniformity <0.2 dB to ensure consistent signal quality.
- Mechanical Reliability: Guide pins enable repeatable mating (≥1000 cycles) without alignment drift. Withstands vibration, temperature fluctuations (-40℃ to +85℃), and module assembly stress.
- High Density: Compact MT connector footprint (~6.4mm × 2.5mm for 24-fiber) allows high-channel integration in space-constrained modules like QSFP-DD, OSFP, or 800G modules.
- Compatibility: Fully compliant with IEC 61754-20 (MT connector standard) and compatible with FA-MT arrays, AWG MUX/DEMUX, and other optical module components.
Typical Applications
High-Speed Transceivers
Used in QSFP28, QSFP-DD, OSFP, and 800G/1.6T modules to connect internal photonic components to external ports, supporting parallel transmission protocols (e.g., 4×25G, 8×100G).
Parallel Architectures
Integrated into PSM4 (Parallel Single Mode 4-channel) or SR4 (Short-Reach 4-channel) modules for high-density data center and enterprise network applications.
Internal Interconnects
Facilitates signal routing between optical chips (e.g., PLC splitters, AWG) and module I/O ports, simplifying assembly and improving manufacturing yield.
Test & Measurement
Utilized as custom-length jumpers in module testing setups to validate parallel signal transmission performance and alignment.
Frequently Asked Questions
What is the primary function of an MT-jumper?
The primary function of an MT-jumper is to establish reliable parallel optical links within optical modules (such as connecting laser arrays, photodetectors, or AWG chips to module ports) or between modules and external fiber arrays, optimizing space and ensuring high alignment accuracy.
What configurations of MT connectors are available?
MT connectors feature rectangular ferrules with precision-machined V-grooves and two guide pins for alignment. They are available in male (with guide pins) or female (with guide pin holes) configurations, paired according to the specific module design.
Which fiber types and channel counts do MT-jumpers support?
They are compatible with both multimode (OM3/OM4/OM5, 50/125 μm or 62.5/125 μm) and single-mode (OS1/OS2, 9/125 μm) fibers. Common channel configurations include 12-fiber, 24-fiber, or 48-fiber arrays.
What are the typical insertion loss and return loss values?
Typical insertion loss is <0.3 dB per channel for multimode and <0.5 dB per channel for single-mode. Return loss values are >45 dB (multimode UPC), >55 dB (single-mode UPC), and >60 dB (single-mode APC).
In what high-speed modules are MT-jumpers typically applied?
They are commonly used in high-speed optical transceivers such as QSFP28, QSFP-DD, OSFP, and 800G/1.6T modules, supporting parallel transmission protocols like 4×25G for 100G and 8×100G for 800G.
How do MT-jumpers perform under harsh environmental conditions?
MT-jumpers exhibit high mechanical reliability, withstanding temperature fluctuations from -40℃ to +85℃, vibration, and module assembly stress while maintaining repeatable mating up to 1000 cycles without alignment drift.
