Customized MT-Jumper for 100G/200G High-Speed Transceivers - China Suppliers & Factory Direct Solutions
It is a compact optical jumper with MT (Mechanical Transfer) connectors pre-terminated at both ends—an industry-standard high-density interface. 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 supports multi-channel signal transmission in a single connector, optimizing space and ensuring alignment accuracy for high-speed applications.
Rectangular ferrule (typically ceramic zirconia or LCP plastic) with precision-machined V-grooves to secure fibers. Equipped with two guide pins for self-alignment, ensuring micron-level core positioning. Available in male (with guide pins) or female (with guide pin holes) configurations.
Bundled in a linear array, 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 counts include 12-fiber, 24-fiber, or 48-fiber.
Short-length cable (typically 10–50 mm, tailored to module internal space) with a thin, flexible jacket (e.g., PVC or LSZH) for easy routing. Reinforced with aramid yarn or glass fiber to resist tensile stress and bending damage.
Polished to UPC (Ultra Physical Contact) or APC (Angled Physical Contact) standards. UPC is standard for multimode (return loss >45 dB) and single-mode (return loss >55 dB), while APC (return loss >60 dB) is used for low-reflection single-mode applications.
- 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 across all paths.
- Mechanical Reliability Guide pins enable repeatable mating (≥1000 cycles) without alignment drift. The robust ferrule and cable design withstands vibration, temperature fluctuations (-40℃ to +85℃), and module assembly stress.
- High Density Compact MT connector footprint (e.g., 24-fiber MT ferrule: ~6.4mm × 2.5mm) allows high-channel integration in space-constrained modules (e.g., QSFP-DD, OSFP, or 800G modules).
- Compatibility Compliant with IEC 61754-20 (MT connector standard) and compatible with FA-MT arrays, AWG MUX/DEMUX, and other optical module components.
Used in QSFP28, QSFP-DD, OSFP, and 800G/1.6T modules to connect internal photonic components (lasers, detectors) to external ports, supporting parallel transmission protocols (e.g., 4×25G for 100G, 8×100G for 800G).
Integrated into PSM4 (Parallel Single Mode 4-channel) or SR4 (Short-Reach 4-channel) modules for data center and enterprise network applications.
Facilitates signal routing between optical chips (e.g., PLC splitters, AWG) and module I/O ports, simplifying assembly and improving manufacturing yield.
Used as a custom-length jumper in module testing setups to validate parallel signal transmission performance.
