The FT-D6180-421 uses a high-performance GaAs PIN photo-detector packaged with a transimpedance amplifier designed to meet performance requirements for 10Gbps data communication over multi-mode optical fiber at 850nm. Applications include Ethernet, Fiber Channel and ATM protocols. The optical assembly is designed to interface either 50mm or 62.5mm multi-mode fiber.  
The FT-D6180-421 is designed to be paired with Advanced Optical Components FT-E6x9x VCSEL 10Gbps TOSA products (see data sheets for FT-E6x9x products).

These parts are designed to provide the latching and release mechanism for pluggable SFP+ modules.  Finisar offers the bail and latch as piece parts for external sale to module manufacturers for use within particular modules.  The bail is available in various colors as listed in the Product Features tab.

The FT-E7192-xxx uses a high-performance Vertical Cavity Surface Emitting Laser (VCSEL) designed to meet performance requirements for 1/2/4/8 Gbps data communication over multimode optical fiber for the ANSI X2.T11 Fibre Channel protocols. The optical assembly is designed to interface either 50μm or 62.5μm multimode fiber and ensure launch conditioning requirements compatibility with enhanced bandwidth fiber as specified by TIA 455-203.

The DFB-1310-10LR-LCA is specifically designed for applications based on several optical communications standards, including IEEE 10GBASE-LR, STM64, STM64 FEC, 10GFC, 10G GbE, 10G GbE FEC and 10GFC FEC. Excellent optical performance is achieved by matching the electrical characteristics of the TOSA and laser to the external circuitry.  The TOSA is designed to be paired with the 10G LR ROSA PIN-1310-LR-x.

The FT-E6x92-x61 uses a high-performance Vertical Cavity Surface Emitting Laser (VCSEL) designed to meet performance requirements for 10Gbps data communication over multimode optical fiber. Applications include Ethernet, Fibre Channel and ATM protocols. The optical assembly is designed to interface either 50µm or 62.5µm multimode fiber and ensure launch conditioning requirements compatibility with enhanced bandwidth fiber as specified by TIA 455-203.
The FT-E6x92-x61 incorporates a power monitoring photodiode that can be used for temperature compensation, average power control, and for compliance with Class 1 eye safety limits.
