40 and 100 Gbps CFP GaAs optical transceiver modules for Ethernet
The new modules employ the firm's 850 nm gallium arsenide VCSEL and photodetector technology. They are designed to power next-generation capabilities that service providers are demanding
Emcore Corporation is introducing two new 40 Gbps and 100 Gbps form-factor pluggable optical transceiver modules for 40 and 100 Gigabit Ethernet short reach applications, respectively.
This highly flexible form-factor supports 40GBASE-SR4 and 100GBASE-SR10 optical interfaces with link distances up to 150 metres over multimode optical fibre 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 an Emcore GaAs 850 nm wavelength 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.
"These new CFP transceiver modules utilise our latest VCSEL and photodetector technology and are designed to power next-generation capabilities that service providers are demanding," comments Jaime Reloj, Emcore's Vice President of Business Development.
"By leveraging our in-house optoelectronic component capability, we can optimise optical performance and tailor solutions to very specific customer needs. Emcore will continue to advance the technology for high-performance data and telecommunications and demonstrate the same quality, reliability, on-time delivery and competitive pricing our customers have come to expect," continues Reloj.
Emcore will be at the 2012 Optical Fibre Conference (OFC) at the Los Angeles Convention Centre between March 6th and 8th in the Corporate Village, suites 2555 and 2557.
