Avago Technologies, a leading supplier of analog interface components for wireless, wireline, and industrial applications, announced the availability of a new series of 100GbE-LR4 transmit optical subassembly (TOSA) and receive optical subassembly (ROSA) devices, the AFCP-T4X25EL and AFCP-R4X25PL, respectively. This new series of devices is designed for use in the new CFP4 optical transceiver form factor enabling carrier grade transmission over fiber links of up to 10 km. These highly compact TOSA and ROSA devices expand Avago's growing portfolio of optical component solutions leveraging monolithic and hybrid photonic integrated circuit technologies to enable next generation high-density router and switch applications.

The AFCP-T4X25EL TOSA delivers four wavelengths on the LAN-WDM grid in the 1300nm wavelength window on a single optical output. The TOSA integrates four high performance 28Gbps electro-absorption modulated lasers (EMLs) and an optical multiplexer to combine the laser wavelengths. The AFCP-R4X25PL ROSA integrates an optical de-multiplexer to separate the four incoming LAN-WDM wavelengths, an array of four high performance 28Gbps PIN photo-detectors, and a quad trans-impedance amplifier.

"The development of these new optical engines reinforces Avago's continued commitment to providing advanced optical component solutions to enable more compact transceiver solutions for higher-density links while lowering system power consumption for next generation networks,"

said Stefan Rochus, Director of Optical Components Product Marketing at Avago Technologies. "This new series of TOSA/ROSA devices is ideally suited for the new CFP4 optical transceiver form factor that has gained industry-wide adoption for 100GbE-LR4 interfaces."

Avago will be showcasing the new TOSA and ROSA devices in the Avago booth 3160 at the OFC 2014 exhibition in San Francisco, California from March 11th to 13th.
