Emcore Intros CFPs

ALBUQUERQUE, N.M. -- EMCORE Corporation (Nasdaq:EMKR), a leading provider of compound semiconductor-based components and subsystems for the fiber optics and solar power markets, announced today the new 40 Gigabits per second (Gbps) and 100 Gbps Form-factor Pluggable (CFP) optical transceiver modules for 40 and 100 Gigabit Ethernet (GbE) short reach applications, respectively. This highly flexible form-factor supports 40GBASE-SR4 and 100GBASE-SR10 optical interfaces with link distances up to 150 meters over multimode optical fiber and facilitates system design options including Ethernet rack-to-rack, ganged serial links, logic-logic data links, board-to-board and shelf-to-shelf configurations.

The SR4 CFP transceiver module is a 4-channel design with four synchronous 10.3125 Gbps electrical input lanes. The SR10 CFP transceiver module is a 10-channel design with ten synchronous 10.3125 Gbps electrical input lanes. In both modules electrical signals are retimed by a multi-lane data clock recovery unit and then converted to optical signals using a multi-lane laser driver and EMCORE Gallium Arsenide (GaAs) 850 nm wavelength Vertical Cavity Surface Emitting Laser (VCSEL) array. The optical signals are converted to electrical signals using an EMCORE GaAs PIN photodetector array, along with a multi-lane transimpedance amplifier and are retimed and delivered to the host.

Both the EMCORE SR4 and SR10 CFP transceivers are hot-pluggable and hot-swappable and have control and monitoring functions that are accessed through the microcontroller via a two-wire serial MDIO (Management Data Input/Output) port. The electrical interface consists of a 148-pin edge-connector compliant with the CFP MSA industry standard.
