Description
The Calix 100-01957 is a Small Form-factor Pluggable (SFP) transceiver module designed for efficient data transmission over single-mode fiber (SMF). It supports distances up to 20 kilometers, making it suitable for access network deployments and shorter point-to-point links where extended reach is not the primary requirement. This module utilizes Bi-Directional (BX) technology, specifically the BX-U variant, which allows for simultaneous transmission and reception of data over a single strand of fiber. It achieves this by employing different wavelengths for each direction: 1310nm for transmitting and 1490nm for receiving. This configuration is beneficial for conserving fiber resources in network infrastructure. The transceiver features a standard LC connector for secure and reliable fiber optic connectivity. It supports data rates up to 1.25 Gb/s, commonly used in Gigabit Ethernet applications. The inclusion of Digital Diagnostic Monitoring (DDM) provides real-time insights into the transceiver's operational status, including optical power levels, temperature, and voltage, which is essential for network management, performance monitoring, and fault diagnosis. The 20km reach is achieved through optimized optical components and power budget suitable for this distance.
