Emcore launches 40 and 100G CFP transceiver modules for Ethernet applications

Emcore Corp of Albuquerque, NM, USA, which makes components, subsystems and systems for the fiber-optic and solar power markets, has launched 40Gbps and 100Gbps form-factor pluggable (CFP) optical transceiver modules for 40 and 100 Gigabit Ethernet (GbE) short-reach applications, respectively.

The firm says that the highly flexible form-factor supports 40GBASE-SR4 and 100GBASE-SR10 optical interfaces with link distances up to 150m 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 module is a 4-channel design with four synchronous 10.3125Gbps electrical input lanes. The SR10 CFP module is a 10-channel design with ten synchronous 10.3125Gbps electrical input lanes. In both, the electrical signals are re-timed 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) 850nm-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 (TIA) and are re-timed and delivered to the host.

Both the 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 (multi-source agreement) industry standard.

“These new CFP transceiver modules utilize our latest VCSEL and photodetector technology and are designed to power next-generation capabilities that service providers are demanding,” says VP of business development Jaime Reloj. “By leveraging our in-house optoelectronic component capability, we can optimize optical performance and tailor solutions to very specific customer needs.”

Emcore is exhibiting in the Corporate Village (suites 2555 & 2557) at the Optical Fiber Communication Conference and Exhibition/National Fiber Optic Engineers Conference (OFC/NFOEC 2012) in Los Angeles (6-8 March).
