Oclaro samples 2km-reach multi-rate 10G SFP+ CPRI transceiver for wireless backhaul

Oclaro Inc of San Jose, CA, USA, which provides lasers and optical components, modules and subsystems for the optical communications, industrial, and consumer laser markets, is sampling the TRS5013WV, a low-cost 10G Ethernet SFP+ transceiver for single-mode-fiber applications up to 2km.

The 10G SFP+ CPRI transceiver is a pluggable module optimized for wireless backhaul applications and is compliant with the IEEE 10G Ethernet transceiver standards as required by the Common Public Radio Interface (CPRI) specification covering the CPRI rates from 2457.6Mb/s (Option 3) to 9830.4Mb/s (Option 7). The SFP+ CPRI transceiver uses a Fabry-Perot (FP) laser to keep design costs low while offering high performance with a reach of 2km over single-mode fiber and an extended temperature range of -40°C to +85°C, covering the majority of antenna backhaul connections. The transceiver is also compliant with OBSAI specifications and applications.

Mobile devices continue to grow in numbers and usage as the preferred interface for high-bandwidth media consumption and video communications, says Oclaro. This is driving a rapid increase in bandwidth needs throughout the wireless backhaul network, including the very cost-sensitive ‘last mile’ to the antenna. A very high percentage of these CPRI links tend to be less than 2km in length. However, a CPRI-compliant SFP+ transceiver cost-optimized for these short distances has not been available until now, and the industry has had to rely on more expensive transceivers with a reach of 10km. Oclaro’s 10G SFP+ CPRI transceiver fills the need for these distances while meeting the harsh environmental requirements for wireless backhaul applications, says the firm.

“Upgrades of wireless networks to 4G create a strong demand for optical connectivity to support the wireless infrastructure,” comments Vladimir Kozlov PhD., founder & CEO of LightCounting Market Research. “A high percentage of the connections between the base-station and antenna towers are relatively short, requiring transceivers that can support distances up to 2km. Demand for 10Gb/s connectivity will be strong within the wireless industry. Over the past three years, this market segment has experienced annual growth rates of 50-100% per year. This has led the transition to higher data rates: from 3Gb/s to 6Gb/s and now 10Gb/s,” he adds.

“Today’s announcement is another milestone in our quest to offer high-performance cost-efficient transceiver solutions and help enable a bandwidth-rich wireless network infrastructure,” says Atsushi Takai, VP & general manager, Oclaro Japan Inc, Pluggable Division of Modules & Devices business unit.

The 10G SFP+ transceiver for CPRI wireless backhaul applications is sampling now and is expected to be in volume production at the end of 2013.

Oclaro is discussing this newest 10G SFP+ CPRI transceiver with customers in meeting room MR3 during the European Conference and Exhibition on Optical Communications (ECOC 2013) in London, UK (23-25 September).
