About This Part
The Calix 100-02581 is a high-density Compact Small Form-factor Pluggable (CSFP) optical transceiver designed for robust Gigabit Ethernet connectivity. This advanced module, manufactured by Calix, integrates two independent 1 Gigabit Ethernet (1GE) channels within a single CSFP form factor, significantly enhancing port density in network equipment. Operating on a Bi-directional (BIDI) principle, it utilizes a single optical fiber for both transmit and receive paths, typically employing distinct wavelengths to achieve full-duplex communication. Specifically, this variant operates at a transmit wavelength of 1490nm, paired with a complementary receive wavelength (e.g., 1310nm or 1550nm, depending on the BIDI pairing), and is engineered to support link distances of up to 10 kilometers over single-mode fiber. Its dual-channel capability makes it an ideal solution for applications requiring efficient use of fiber infrastructure while maintaining high performance and reliability for data transmission. The Calix 100-02581 transceiver is primarily deployed in access networks, such as Fiber-to-the-x (FTTx) architectures, enterprise networks, and metropolitan area networks where efficient fiber utilization and high port density are critical. It is compatible with a wide range of networking platforms that support CSFP interfaces, including Calix Optical Line Terminals (OLTs), Ethernet switches, and routers. Telecommunication operators, Internet Service Providers (ISPs), and large enterprises leverage this module to extend Gigabit Ethernet services to subscribers or remote offices over existing single-mode fiber infrastructure. By offering two independent 1GE links within a compact form factor, it effectively addresses challenges related to limited rack space and fiber availability, enabling network providers to double their port capacity without requiring additional chassis or line cards. This module serves as a cost-effective upgrade path for networks seeking to enhance their 1GE service delivery capabilities or replace less efficient, single-channel SFP transceivers, optimizing both operational expenditure and capital expenditure.
