The CWDM-GBIC-1590 is a 1000BASE-CWDM GBIC transceiver operating at 1590 nm for single-mode fiber, designed to extend Gigabit Ethernet links over CWDM networks.
The CWDM-GBIC-1590 operates at a central wavelength of 1590 nm, compliant with ITU-T G.694.2 CWDM channel spacing for low–loss single-mode transmission.
The CWDM-GBIC-1590 supports distances up to 80 km over standard single-mode fiber (SMF-28) at 1000 Mbps, assuming a 0.36 dB/km fiber attenuation.
Yes, the CWDM-GBIC-1590 is hot-swappable and interoperable with any Cisco-style GBIC slot or equivalent vendor port supporting 1000BASE-CWDM.
You can multiplex the CWDM-GBIC-1590 on a CWDM MUX/DEMUX with other ITU-T compliant CWDM modules, provided each uses a unique wavelength channel.
Yes, the CWDM-GBIC-1590 is fully hot-swappable, allowing insertion or removal without powering down the host device.
The CWDM-GBIC-1590 is designed exclusively for single-mode fiber (SMF), ensuring minimal dispersion and optimal performance at 1590 nm.
The CWDM-GBIC-1590 supports a 1.25 Gbps line rate, fully compliant with IEEE 802.3ah 1000BASE-CWDM specifications.
The CWDM-GBIC-1590 operates reliably from 0°C to 70°C (commercial range) and can be ordered in an extended –40°C to 85°C option for harsh environments.
The CWDM-GBIC-1590 consumes less than 1.0 W at full operational load, offering energy-efficient CWDM performance.
To install, gently slide the CWDM-GBIC-1590 into an empty GBIC port until it clicks, then secure the retention clip; the host will automatically detect the module.
The CWDM-GBIC-1590 supports Digital Optical Monitoring (DOM), allowing real-time readings of optical output, input power, temperature, and laser bias current.
Use the host device’s built-in CLI or network management system to read DOM metrics and perform standard Ethernet loopback tests for link integrity.
Yes, the CWDM-GBIC-1590 is fully compatible with ring architectures, enabling redundant Gigabit links over single-mode fiber with wavelength-specific routing.
Check the part number CWDM-GBIC-1590, manufacturer’s label, holographic seal, and confirm DOM data fields to ensure authenticity and OEM compliance.
