Overview
The MPBC 2RU Raman Counter-Pump Module is a high-stability, rack-mountable optical amplifier subsystem engineered for distributed Raman amplification in fiber-optic communication systems. Unlike conventional forward-pumping configurations, this module delivers precisely controlled counter-propagating pump light—typically at 1420 nm, 1450 nm, or 1480 nm—to enable low-noise, high-gain signal amplification across C-band (1530–1565 nm) and L-band (1565–1625 nm) wavelengths. Its design adheres to the fundamental principles of stimulated Raman scattering (SRS), where pump photons transfer energy to longer-wavelength signal photons via vibrational modes in the silica fiber core. The 2RU (88.9 mm height) 19-inch rack-optimized mechanical architecture ensures seamless integration into telecom central offices, CATV headends, and DWDM line systems requiring space-constrained, thermally stable pump sources with minimal backward ASE leakage.
Key Features
- Counter-directional pump architecture optimized for noise figure reduction in distributed Raman amplifiers
- Integrated high-power pump lasers with wavelength stabilization via FBG locking or TEC-controlled DFB/DBR designs
- Optical isolation exceeding 45 dB to suppress back-reflected signal light and prevent laser diode instability
- Real-time optical power monitoring via calibrated tap couplers and photodiodes, supporting closed-loop power regulation
- Rack-mounted 2RU chassis with front-panel status indicators (pump ON/OFF, fault, temperature alarm) and rear-panel IEC C14 AC input
- Compliance with IEC 60825-1 (Laser Safety Class 3B/4) and EN 61326-1 (EMC for industrial environments)
- Operating temperature range: 0 °C to +50 °C; storage: −20 °C to +70 °C; relative humidity: 5–95% non-condensing
Sample Compatibility & Compliance
The MPBC 2RU is designed for interoperability with standard single-mode fiber (ITU-T G.652.D/G.655) and compatible with industry-standard Raman gain fibers (e.g., TrueWave RS, LEAF). It supports dual-pump and multi-pump configurations when cascaded with additional MPBC units under centralized control. Regulatory compliance includes CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), RoHS 2011/65/EU, and REACH SVHC screening. For deployment in regulated environments—including carrier-grade networks subject to Telcordia GR-1312-CORE or ITU-T G.664—its firmware supports deterministic startup sequences, thermal derating profiles, and fault logging aligned with network management system (NMS) requirements.
Software & Data Management
Remote operation is enabled via embedded Ethernet (10/100BASE-TX) supporting SNMP v2c/v3 and HTTP/HTTPS interfaces. Configuration parameters—including target output power, pump wavelength setpoints, safety interlock thresholds, and alarm reporting levels—are managed through a browser-based GUI compliant with modern TLS 1.2+ standards. For automated test environments, SCPI-compliant command sets (e.g., :POW:LEV?;, :LAS:STAT?) allow integration with LabVIEW, Python (pyvisa), or MATLAB. All operational logs—including laser runtime hours, temperature excursions, and power deviation events—are timestamped and stored in non-volatile memory with configurable retention (up to 30 days). Audit trails meet GLP-aligned traceability requirements when used in R&D validation labs.
Applications
- Distributed Raman amplification in long-haul and submarine optical transmission systems
- Noise-suppressed pre-amplification for coherent receivers in 400G/800G ZR and OpenZR+ modules
- Hybrid EDFA/Raman configurations for extended reach in metro-core networks
- Test-bed pumping in photonic integrated circuit (PIC) characterization setups
- Research on SRS-based parametric gain, supercontinuum generation, and Brillouin-Raman crosstalk mitigation
FAQ
What pump wavelengths are supported by the MPBC 2RU module?
Standard configurations include 1420 nm, 1450 nm, and 1480 nm; custom wavelengths between 1360–1500 nm are available upon request with minimum order quantity.
Does the module support automatic power leveling across temperature variations?
Yes—integrated TEC control and photodiode feedback loops maintain output power stability within ±0.1 dB over the full operating temperature range.
Can multiple MPBC 2RU units be synchronized for multi-wavelength pumping?
Yes—via external TTL trigger input or master-slave Ethernet coordination using IEEE 1588 PTP for sub-microsecond pump timing alignment.
Is the module compatible with third-party Raman gain simulators such as OptiSystem or VPItransmissionMaker?
Yes—manufacturer-provided S-parameter files and pump spectral models (including ASE noise floor data) are supplied for accurate system-level simulation.
What documentation is provided for regulatory audits?
Full Declaration of Conformity, EC Type Examination Certificate (if applicable), laser safety classification report, and traceable calibration certificates for all internal photodetectors and temperature sensors.
