Overview

The CzechLight SDN Dual BiDi EDFA (Erbium-Doped Fiber Amplifier) amplifies optical signals in both directions over a single fiber. It contains two independent amplifier modules:

• C-band module: 1540–1547 nm

• L-band module: 1572 nm

Key features

• Two independent bidirectional EDFA modules (C-band and 1572 nm)

• Four low-noise, hot-swappable fans

• Redundant, hot-swappable power supplies (100–230 V AC or 48 V DC)

• Operating mode selectable independently for each module:

  • ACC – Automatic Current Control (manual pump current)

  • AGC – Automatic Gain Control

• Remote management: SSH2 CLI, local console via micro-USB

• Password and public-key authentication

• SDN control: NETCONF and RESTCONF, YANG model

• IPv4 and IPv6, DNS, firewall, alarm log, NTP time synchronization

• Monitoring: operating mode, pump current, input/output power, laser diode current, temperature, power supplies, fan speed, alarms
