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

Introduction

    As fiber optic networks grow in complexity, the ability to manage, route, and protect multiple optical signals becomes critical. Network operators, system integrators, and test engineers face a common challenge: how to efficiently switch between dozens of fiber paths without compromising signal integrity or consuming excessive rack space.

    Enter the high-port-count optical switch. Devices like the Coreray 1×64 rack-mount optical switch provide a dense, reliable, and automated solution for routing one input to any of 64 outputs. This article examines the technology behind these switches, their applications in modern networks, and why mechanical switching remains the preferred choice for high-performance fiber management.

The Need for High-Density Optical Switching

    Fiber optic networks have evolved from simple point-to-point links to complex meshes supporting cloud computing, 5G backhaul, and hyperscale data centers. Key drivers for high-port-count switches include:

·         Network Automation: Remote reconfiguration without physical patching

·         Protection Switching: Instant failover to backup paths

·         Multi-Channel Monitoring: Sequentially testing dozens of fibers with one instrument

·         Space Efficiency: Reducing fiber management hardware in crowded racks

A 1×64 switch replaces 64 individual 1×2 switches or complex manual patch panels, saving both space and cost while enabling software-controlled automation.

Technology Deep Dive: Mechanical Switching at 64 Ports

Mechanical vs. MEMS for High Port Counts

    Two primary technologies compete in the optical switch market: MEMS (Micro-Electro-Mechanical Systems) and mechanical (motor-driven) switches. For 1×64 configurations, each has trade-offs:

    For applications requiring ultra-low loss, high isolation, and broad wavelength operation, mechanical optical switches remain the workhorse, especially at 1310nm where long-haul networks demand minimal attenuation.

Mechanical Design for 1×64

Achieving 64 output ports in a compact 1U module requires precision engineering:

·         Rotating Mirror/Prism: A single input collimator directs light to a rotating element. This element (mirror or prism) deflects the beam toward one of 64 output collimators arranged in a circular or linear array.

·         Stepper Motor Control: A high-resolution stepper motor positions the rotating element with micron-level accuracy, ensuring <0.1dB repeatability.

·         Collimator Array: 64 output collimators are precisely aligned to receive the deflected beam with minimal loss.

·         Optical Design: Anti-reflection coatings at 1310nm maximize transmission, while precision mechanics prevent stray light (ensuring 55dB crosstalk).

Rack-Mount Integration

The 1U form factor (44mm height) is standard for telecom and data center equipment. Key integration features include:

·         Front/Rear Fiber Exit: Accommodates different cabling infrastructures

·         LC Connectors: Industry standard for high-density patch panels

·         Cable Management: Integrated guides prevent fiber bending and stress

·         Control Interface: DB9 RS232 for easy connection to network management systems

Application Scenarios

1. Automated Fiber Protection Switching (APPS)

    In metro and long-haul networks, fiber cuts are inevitable. A 1×64 optical switch at a central office can monitor 64 working fibers and instantly switch to 64 protection fibers upon signal loss. The low 1.2dB loss ensures protection paths do not introduce significant attenuation, while 55dB isolation prevents crosstalk between working and protection channels.

Case Example: A regional telecom provider uses Coreray 1x64 switches at aggregation points. When a main fiber is cut, the switch reroutes traffic to a diverse physical path within 10ms, maintaining service continuity.

2. Multi-Channel Optical Power Monitoring

    Network operators must periodically measure optical power at multiple points. A single optical power meter connected to a 1×64 switch can sequentially monitor 64 different fibers. The high isolation ensures measurements are not contaminated by adjacent channels, while low loss preserves signal strength for accurate readings.

Benefits: Reduces monitoring equipment cost by 64x, simplifies calibration, and enables automated logging.

3. Automated Test Systems (ATS) for Component Manufacturing

    Fiber optic component manufacturers (e.g., couplers, isolators, DWDM modules) need to test hundreds of devices daily. A 1×64 switch allows a single laser source and power meter to test 64 devices sequentially. The RS232 control integrates seamlessly with LabVIEW or Python test scripts.

Result: Faster throughput, reduced operator intervention, and consistent test conditions.

4. Data Center Network Reconfiguration

    As data centers grow, so does the need to reconfigure optical connections between servers and storage. Manual patching is slow and error-prone. A 1×64 switch in the main distribution area enables software-defined optical patching, allowing network administrators to change topologies on demand.

Advantage: Supports dynamic resource allocation, disaster recovery testing, and equipment maintenance without physical visits.

5. Research and Development

    Optical labs often require routing signals to multiple measurement instruments (OSA, power meter, polarization analyzer). A 1×64 switch simplifies setup changes and enables automated characterization of optical devices across multiple channels.

Control and Integration

RS232 Protocol

The Coreray 1x64 switch uses a simple ASCII command set over RS232 (baud rate 9600, 8N1). Example commands:

·         CHx – Switch to channel x (1-64)

·         STAT? – Query current channel

·         SAVEx – Save current channel as power-on default

·         RESET – Return to default channel

TTL Interface

For embedded systems, a 5V TTL header provides direct channel selection via binary addressing (6 bits for 64 channels) plus strobe signals.

Software Integration

Drivers and example code are available for:

·         LabVIEW

·         Python (pySerial)

·         C/C++

·         MATLAB
