NE85630-T1-R25-A

Overview

The NE85630-T1-R25-A is a laser diode module manufactured by CEL, designed for high-speed optical transmission applications. It operates at a nominal wavelength of 1550 nm and supports data rates up to 10 Gb/s. The device integrates a Distributed Feedback (DFB) laser structure with an integrated electro-absorption modulator (EAM) to achieve low dispersion penalty and high extinction ratio. This configuration makes it suitable for long-reach Dense Wavelength Division Multiplexing (DWDM) systems compliant with ITU-T standards. The module typically features a thermoelectric cooler (TEC) and monitor photodiodes for precise control of the laser temperature and output power, ensuring stable performance across varying environmental conditions.

Feature Summary

• Integrated Electro-Absorption Modulator (EAM) for high-speed signal modulation
• Distributed Feedback (DFB) laser structure for narrow linewidth and wavelength stability
• Built-in Thermoelectric Cooler (TEC) for active temperature regulation
• Monitor Photodiodes for real-time tracking of back-facet and front-facet optical power

Applications

• Long-reach DWDM optical transport networks
• Metro and regional fiber optic communication links
• High-capacity backbone transmission systems

Procurement Notes

Verify the specific suffix codes on the component label against the manufacturer's official datasheet to confirm exact wavelength grid, cooling requirements, and pinout configuration. Ensure that the ordering information matches the required ITU-T channel spacing and operating temperature range for your specific system design before finalizing procurement.

Selection Notes

Select this module based on the required transmission distance and dispersion tolerance. Confirm compatibility with your system's DWDM grid specifications. Evaluate the thermal management requirements provided in the datasheet to ensure adequate heat sinking or TEC drive capability is available in the host equipment design.

Part Context

This component belongs to CEL's portfolio of high-performance laser modules for telecommunications. It represents a class of integrated transmitter solutions that combine laser generation and modulation in a single package to reduce size and improve reliability compared to discrete component assemblies.

Replacement Considerations

Check for direct cross-reference part numbers from CEL or other manufacturers offering identical EAM-DFB integration. Verify that any substitute matches the mechanical footprint, pin assignment, and electrical interface specifications exactly to avoid redesign efforts.
