NEON’s high-speed DFB DML laser diode modules include the NY13D, NY15D, NYCMD, and NY55D series, each designed for different advanced fiber optic communication applications.

Product Overview

• NY13D, NY15D, and NYCMD Series
  These are directly modulated DFB laser modules engineered for linear fiber optic communications across very wide bandwidths. They are excellent alternatives to coaxial cable systems for transmitting 12 GHz or 18 GHz signals, delivering superior signal quality and reliability. By transmitting RF signals in their original format, they enhance performance in applications such as antenna remoting, telemetry, timing, reference signal distribution, measurement, and delay lines.

• NY55D Series
  The NY55D high-power DFB laser diode is designed as a wavelength-selected continuous-wave (CW) optical source for use with external modulators in CATV and DWDM networks. It is particularly suitable for super trunking and distribution applications.

  • Supports ITU Grid-compliant wavelengths (range and channel definition).

  • Provides high optical output power up to 100 mW.

Key Applications

• Antenna Remoting

• Cellular and PCS Networks

• Analog RF Link Transmission

• Military Communications

• Tracking, Telemetry & Control

Features of DFB DML Laser Module

• High Dynamic Range

• Up to 18 GHz Bandwidth

• Low Threshold Current

• High Output Power

• Wide Operating Temperature: -40℃ to +70℃

• Excellent Reliability

Working Principle

When the injection current of the DFB laser diode module varies with the modulation signal, the carrier concentration in the laser cavity changes accordingly. This variation alters the optical gain in the active region, causing the optical output power of the module to follow the modulation signal precisely.
