In booth #702 at the European Conference on Optical Communication (ECOC 2015) in Valencia, Spain (28-30 September), GigOptix Inc of San Jose, CA, USA (a fabless supplier of high-speed semiconductor and optical communications components for long-haul and metro telecoms, cloud and data-center connectivity datacoms, point-to-point backhaul wireless applications, and interactive interfaces for consumer electronics links via fiber-optic and wireless networks) is showcasing a live show-floor demo utilizing its third-generation 100Gbps short-reach chipset with its new 28Gbps quad-channel CMOS CDR (clock & data recovery) product.
The HXC42400 quad CMOS CDR is a new addition to GigOptix's datacom portfolio, resulting from the acquisition of Terasquare, and complements the HXT8204 28Gbps quad-channel vertical-cavity surface-emitting laser (VCSEL) driver array and HXR8204 28Gbps trans-impedance (TIA) receiver array (both launched in March) to enable next-generation short-reach SR4 (100m) and extended-reach SR4 (eSR4 – 300m) module and active optical cable (AOC) applications.
The datacom demo is showcasing:
the HXC42400: a 28Gbps 4-channel CMOS CDR/re-timer designed for low-power 100GbE (QSFP28) modules, 100GbE AOC, and supporting OTN OTU4, 32G Fibre Channel, and EDR Infiniband. the HXT8204: a 28Gbps 4-channel VCSEL driver designed for compact, low-power 100GbE SR4 optical transmitter pluggable modules and AOCs. the HXR8204: a 28Gbps 4-channel TIA with integrated limiting amplifier receiver array designed for high capacity datacom 100GbE SR4 pluggable modules and AOCs.
The HXC42400, HXT8204 and HXR8204 are suitable for optical module, active optical cable, and optical engine applications with their partitioning of the CDR power dissipation from the temperature-sensitive, high-performance VCSEL, VCSEL driver, photo-detector, and TIA circuit elements for 100m and extended-reach applications module or AOC applications. The HXC42400 quad CDR solution is applicable to 100GbE (QSFP28) module, OTN OTU4, 32Gbps Fibre Channel, and EDR Infiniband applications.
In addition, a live demonstration by BrPhotonics is showcasing:
a 100Gbps Integrated TOSA Reference Platform for CFP2 transceivers: a 100Gbps DP-QPSK TOSA reference platform with 100Gbps DP-QPSK polymer modulator chip, example coherent receiver, and biasing circuitry.
In partnership with GigOptix and CPqD (an independent Brazil-based research center focused on information & communication technologies with activities in system- and device-level optical communications), the Brazilian joint venture BrPhotonics is demonstrating a coherent optical link design for 100Gbps long-haul communications with a complete CFP2 TOSA and separate receive path circuitry. The integrated CFP2 TOSA and Reference Platform utilize a linear quad MZM driver, a BrPhotonics 100Gbps DP-QPSK Thin Film Polymer on Silicon (TFPS) modulator, and an independent tunable laser. Discrete coherent receiver devices are located on the reference PCB as well as the GigOptix bias boards. The demonstration setup provides eye-diagram display on a real-time sampling scope, and X and Y polarization observation via optical constellation analyzer.
