Key Features of Arista SFP-1G-CZ-1450 Compatible LINK-PP 1.25G SFP
Arista SFP-1G-CZ-1450 Compatible LINK-PP delivers reliable optical transmission for metropolitan-area network links over a single 1450nm CWDM channel. This module combines standard SFP mechanical compatibility with extended 80km reach and digital diagnostics. Its design prioritizes fiber utilization efficiency, real-time link supervision, and straightforward integration into existing gigabit equipment.
This optical module adopts a hot-pluggable SFP footprint for effortless installation and replacement without system power-down. It fully complies with SFP MSA specifications, ensuring interoperability with a wide range of switches and routers. The industry-standard electrical interface and housing simplify network upgrades and maintenance tasks.
SFP-1G-CZ-1450: 1 Gbps Connectivity for Metropolitan Fiber Links
The 1Gbps data rate positions this transceiver as a dependable solution for metro-area fiber connections. It handles Ethernet traffic in access rings and aggregation points across city networks, linking central hubs with remote facilities. This 1G speed aligns perfectly with the bandwidth requirements of typical metropolitan applications and ensures seamless operation with existing gigabit-capable equipment.
SFP-1G-CZ-1450 Module with CWDM Technology for Fiber Efficiency
Coarse wavelength division multiplexing allows multiple wavelengths to share one fiber pair, reducing cable infrastructure costs. This module operates as one channel in a standard CWDM grid, enabling capacity expansion without adding new fibers. Network planners can mix it with other CWDM transceivers at different wavelengths for flexible link design.
SFP-1G-CZ-1450 Module with 1450nm Wavelength
The 1450nm center wavelength falls within the CWDM band, offering low attenuation in typical single-mode fiber. This specific wavelength avoids crosstalk with adjacent channels when used in a multiplexed system. It also aligns with common CWDM mux/demux filters for straightforward channel assignment.
An integrated 1450nm DFB laser and high-sensitivity receiver enable error-free operation over distances up to 80km. The link budget accounts for dispersion and loss in standard single-mode fiber, ensuring stable performance across the full reach. This long-haul capability makes it ideal for interconnecting distant campus or city-wide network nodes.
SFP-1G-CZ-1450 Module with Duplex LC Interface
The duplex LC connector provides a secure, polarity-consistent physical interface for single-mode fiber patch cords. This standardized optical interface ensures quick mating with existing fiber plant and distribution panels. It supports both transmit and receive on separate fibers, matching typical CWDM deployment practices.
SFP-1G-CZ-1450 Module with DDM for Real-Time Monitoring
Digital diagnostics monitoring (DDM) continually reports critical parameters such as optical power, supply voltage, temperature, and bias current. Real-time data helps operators detect fiber degradation or connector contamination before service interruptions occur. This monitoring function also facilitates remote fault isolation and proactive link maintenance.
Arista SFP-1G-CZ-1450 Compatible LINK-PP optical transceiver complies with major global standards, including ISO 9001, CE, RoHS, and FCC certifications. These official approvals confirm that the module meets strict international quality, safety, and environmental requirements.

A:
Potentially, yes. The 80km rating is the maximum nominal transmission distance, but the total fiber loss must remain within the module’s optical budget after including fiber attenuation, connector loss, splice loss, and CWDM MUX/DEMUX insertion loss. By

A:
No. For a normal duplex CWDM connection, both ends should use matching 1450nm modules. A 1450nm module should not be directly paired with a 1470nm module. By

Good fit for a long-distance enterprise network where we still have active 1GbE access switches. The 1G SFP format saved us from replacing working equipment while adding another CWDM wavelength to the existing SMF pair.

Installed as part of a multi-vendor switch refresh where legacy access equipment still relies on standard SFP ports. We provided the required host coding information before ordering, and the modules were delivered ready for our planned device profile. On a 57km single-mode fiber link, the 1.25Gbps port negotiated normally and stayed stable through traffic tests. The Duplex LC interface was convenient because the field plant already used LC patch panels, and DOM helped quickly identify one dirty connector during installation.
