Description
The Calix 100-01671-CTEMP-A is a Small Form-factor Pluggable (SFP) transceiver module specifically designed for high-speed data transmission over single-mode fiber (SMF) for distances up to 40 kilometers. This module utilizes Bi-Directional (BX) technology, commonly referred to as BX-D, which allows for simultaneous transmission and reception of data over a single strand of fiber by employing different wavelengths for each direction. This particular model operates with a transmit wavelength of 1490nm and a receive wavelength of 1310nm. This asymmetrical wavelength configuration is typical for certain fiber-to-the-home (FTTH) or point-to-point network architectures where a single fiber pair is utilized efficiently. The standard LC connector ensures a secure and reliable connection to the fiber optic cable. Supporting data rates up to 1.25 Gb/s, the 100-01671-CTEMP-A is suitable for various access network applications. It includes Digital Diagnostic Monitoring (DDM) capabilities, allowing network operators to monitor critical parameters such as optical power, temperature, and voltage in real-time, facilitating network management and troubleshooting. This SFP is designed for demanding environmental conditions, indicated by the '-CTEMP' designation.
