Detailed Explanation of Finisar Optical Module Models

Finisar offers a wide range of optical transceiver modules including SFP, SFP+, QSFP, CFP2, and OSFP models for data center, telecom, and enterprise networks.Overview of Finisar Optical ModulesFinisar manufactures pluggable optical transceivers that convert electrical signals to optical signals and vice versa, supporting high-speed data transmission over fiber networks. Their modules are widely used in data centers, 5G networks, enterprise networks, and telecom backhaul .Key Module FamiliesSFP (Small Form-factor Pluggable): Standardized modules for data rates up to 4 Gb/s, widely used in legacy and modern networks .SFP+: Enhanced SFP modules supporting 10 Gb/s and beyond, with lower power consumption and smaller footprint compared to XFP modules .QSFP/QSFP+: Quad Small Form-factor Pluggable modules for 40 Gb/s links, suitable for high-density data center applications .QSFP28/QSFP112: High-speed modules supporting 100 Gb/s and 400 Gb/s, used in modern Ethernet and telecom networks .CFP2: Compact modules for 100 Gb/s applications, compatible with high-speed optical networks .OSFP (Octal Small Form-factor Pluggable): Modules designed for 400 Gb/s Ethernet, supporting short- and medium-reach single-mode fiber links .Example ModelsFTLX1471D3BTL-EA: 10 Gb/s SFP+ long-reach module compatible with Ericsson equipment .FTLF8519P3BTL: 10 Gb/s SFP+ short-reach module .FTLC9152RGPL: 100 Gb/s QSFP28 transceiver .FTLC1122RDNL: 100 Gb/s CFP2 module .FTL410QE4C: 40 Gb/s QSFP+ short-reach module .FTCE4517E1PxA: 2x400 Gb/s OSFP transceiver for up to 500m single-mode fiber .FTCD4538E1PCM: DR4+ QSFP112 module for 400 Gb/s links up to 2 km single-mode fiber .Features and CompatibilityFinisar modules are multi-brand compatible, supporting Cisco, HP, Huawei, Ericsson, Nokia, and other major telecom brands. They are rigorously tested for plug-and-play reliability, and many models include digital diagnostics via I2C interfaces for monitoring optical performance . Modules are designed for RoHS compliance and operate over extended voltage and temperature ranges .ApplicationsData Centers: High-density QSFP28 and QSFP112 modules for 100G/400G Ethernet.Telecom Networks: SFP/SFP+ and OSFP modules for 5G backhaul and metro networks.Enterprise Networks: Short- and long-reach SFP+ modules for campus and LAN deployments.Passive Optical Networks (PON): GPON OLT access equipment and CWDM/DWDM modules for fiber-to-the-home (FTTH) deployments . Finisar's optical modules provide flexible, high-performance solutions for modern networking needs, supporting a wide range of speeds, distances, and form factors.
