Fixed Dispersion Compensators – DCML

Communication and internet service providers (CSP & ISP) are extending their reach to connect as many as possible, in the most efficient way. Networks using intensity modulation direct detection (IMDD) require a simple, cost-effective, and reliable chromatic dispersion compensation solution. indie’s FBG-based DCML have been widely deployed as essential components of regional and metropolitan networks for more than 15 years. The DCML has dominated the FBG-based dispersion compensation market because the proven-reliable, compact modules are a totally passive solution that features ultra-low latency and low-insertion-loss.

• indie’s channelized FBG technology mitigates both interchannel and intrachannel nonlinear impairments.
• The compact DCML efficiently compensates chromatic dispersion with less than two meters of fiber—much less than the kilometers of fiber required for DCF modules, reducing link latency by 20%.
• The DCML is a completely passive device, making it ideal for networks with limited electrical power budget.

Key Features and Benefits

Ultra-Low Latency:
The DCML features a latency of less than 25 ns, a reduction of over 1000x compared to dispersion compensating fiber (DCF), making it the perfect choice for latency-critical networks.

Efficient:
DCML’s channelized FBGs minimize the generation of non-linear effects, such as self-phase modulation and four-wave mixing, enabling the use of higher transmission power levels.

Compact:
The DCML has dimensions of only 162 x 20 x 9 mm, including the optical circulator.

Reliable:
DCML units are in use within critical networks worldwide and continue to operate after more than 15 years.

Passive:
The DCML is a completely passive, FBG-based device that uses no electrical power.

Rugged:
The DCML’s  athermal package is certified for operation in temperatures ranging from -5 °C to 70 °C (an extended-range version ranging from -40 °C to 85 °C is available for outside plant applications).
