Coreray: Leading Fiber Optic Switch Manufacturer - MEMS & Mechanical Optical Solutions

3V Latching Multimode Fiber Optic Switch 1x2 – Low Loss, Compact Design for Data Centers

Product Overview

    The D1×2 Multimode Optical Switch (3V Latching Type) from Coreray is a high‑performance 1x2 fiber optic switch designed specifically for multimode fiber networks operating at 850 nm. Engineered with advanced latching technology, this switch provides reliable optical path switching while consuming zero power in the steady state – a key advantage for energy‑efficient data centers, test equipment, and industrial networks. As a trusted optical switch manufacturer in China, Coreray delivers components that combine low insertion loss, high return loss, and exceptional thermal stability in an ultra‑compact package.

    The switch utilizes a mechanical actuation mechanism: an internal prism is precisely positioned by a 3V electrical pulse, directing the input light to either output port 1 or port 2. Once switched, the latching design holds the position without continuous power, ensuring stable operation and reducing overall energy consumption by over 30% compared to non‑latching alternatives. With its 50/125 µm multimode fiber, 0.9 mm tight‑buffer pigtails, and LC/PC connectors, this multimode optical switch is ready for integration into high‑density environments.

Key Features

·         Ultra‑Low Insertion Loss
Typical insertion loss of only 0.8 dB (significantly lower than the industry average of 1.2 dB), minimizing signal attenuation and preserving link budget in demanding applications.

·         High Return Loss
≥35 dB return loss (industry standard ≥30 dB) effectively suppresses back‑reflections that can degrade signal quality in high‑speed networks.

·         3V Latching Control
A short 3V electrical pulse toggles the switch; once the state is set, no power is required to maintain it. This “latching” feature reduces power consumption and heat generation, making it ideal for green data centers and battery‑powered field equipment.

·         Compact Footprint
Measuring only 27 × 12 × 8.2 mm, this compact optical switch fits easily into dense panels, patch panels, or portable test instruments.

·         Wide Operating Temperature
Certified for -20°C to +70°C operation, with temperature cycling tests from -40°C to +85°C for 48 hours, ensuring reliability in industrial environments without climate control.

·         Robust Mechanical Design
Based on proven prism‑displacement technology, the switch offers stable optical performance over thousands of switching cycles.

Applications

·         Data Center Optical Switching
Enable rapid reconfiguration of server clusters or storage networks. The latching function maintains the selected path even if power is interrupted, increasing business continuity and simplifying redundancy schemes.

·         Optical Communication Test Equipment
Used in benchtop or portable test sets for accurate signal routing. The low loss and high isolation help maintain low bit‑error rates during measurements.

·         Industrial Optical Network Management
With an operating range of -20°C to +70°C, this industrial fiber optic switch withstands factory floor conditions, providing reliable path selection for control and monitoring systems.

·         5G Fronthaul Networks
Optimized for 850 nm short‑reach multimode links, it supports high‑speed data transmission in distributed antenna systems and small cell backhaul.

How It Works

The D1×2 is a mechanical optical switch that operates like a precise “railroad switch” for light. An input collimator converts the diverging fiber beam into a parallel beam. When a 3V pulse is applied, a miniature electromagnetic actuator moves a mechanical arm, shifting a high‑precision prism into one of two positions:

·         Position A: The prism reflects the beam to output port 1.

·         Position B: The beam passes straight through to output port 2.

Crucially, this is a latching optical switch. After the pulse ends, a permanent magnet or mechanical detent holds the prism in place, requiring no further power. This self‑locking mechanism guarantees state retention during power outages and eliminates continuous power consumption – a major advantage in energy‑sensitive installations.

Technical Specifications

All optical specifications are measured at room temperature with connectors mated.

Frequently Asked Questions (FAQ)

Q1: What is a “latching” optical switch?
A: A latching switch maintains its state (port 1 or port 2) after the drive signal is removed. It only needs a short electrical pulse to change state, consuming zero power in steady state. This makes it ideal for power‑sensitive applications.

Q2: Can I use this switch with single‑mode fiber?
A: The standard model is optimized for 50/125 µm multimode fiber at 850 nm. For single‑mode applications, please contact us for our single‑mode latching switch series.

Q3: What is the switching speed?
A: The mechanical switching time is typically ≤10 ms (including settling). Exact timing depends on the drive circuit.

Q4: How many switching cycles can it endure?
A: This mechanical optical switch is rated for >10 million cycles under normal operating conditions.

Q5: Does it come with test data?
A: Yes, every unit includes an individual test data sheet (hardcopy and electronic) showing insertion loss, return loss, and crosstalk for both paths.

Q6: Can I get it with different connectors?
A: Absolutely. Standard is LC/PC, but we offer SC, FC, ST, and MU connectors. Custom pigtail lengths are also available.
