Dependable gigabit module for expanding CWDM networks.
Consistent wavelength separation and steady performance.
The CWDM-GBIC-1490 is a 1000BASE-CWDM Gigabit Interface Converter (GBIC) module designed for single-mode fiber links at a 1490 nm wavelength.
This GBIC operates at a precise 1490 nm wavelength, optimized for coarse wavelength division multiplexing (CWDM) applications in gigabit networks.
The CWDM-GBIC-1490 requires single-mode fiber (SMF) with LC simplex connectors to ensure optimal signal integrity over long distances.
It supports a maximum reach of up to 60 km over standard single-mode fiber under typical operating conditions.
The module delivers a 1.25 Gbps data rate, fully compliant with IEEE 802.3z 1000BASE standards.
Yes. The CWDM-GBIC-1490 is hot-swappable, allowing you to install or remove it without powering down the host device.
It’s compatible with most CWDM-enabled switches, routers, and media converters from leading brands supporting MSA-compliant GBIC modules.
Insert the GBIC into the device’s transceiver slot until it locks, then connect the single-mode fiber cable to the LC port.
Yes. This module adheres to the Multi-Source Agreement (MSA) for GBIC form factors, ensuring broad interoperability.
Yes. The module supports DOM for real-time monitoring of optical power, temperature, voltage, and laser bias current.
The operating range is 0 °C to 70 °C (32 °F to 158 °F), suitable for standard indoor data center and telecom environments.
No. This module is designed for unidirectional CWDM; bidirectional links require complementary Tx and Rx modules at matched CWDM wavelengths.
Transmit power ranges from –8.0 to 0 dBm, while receiver sensitivity is typically –23 dBm, yielding an optical budget up to 15 dB.
GBIC modules, like the CWDM-GBIC-1490, are larger than SFPs but offer proven reliability and compatibility with legacy gigabit network infrastructures.
The module includes a one-year limited warranty covering manufacturing defects under normal operating and installation conditions.
Use a certified fiber-optic cleaning kit on the LC connector end face, avoid touching the fiber, and keep dust caps in place when not in use.
