VI Systems GmbH has introduced high-speed optical transmitter and receiver modules aimed at multimode fiber transmission in data centers and storage area networks.

The new products include a V10-1300M fiber-coupled optical transmitter module based on a 1310-nm vertical cavity surface emitting laser (VCSEL), and a receiver module designed for the operating wavelength range 900–1350 nm. The first-generation optical transmitter is specified for data rates up to 12.5 Gbps and the receiver is specified for data rates of up to 40 Gbps.

The new modules feature 50/125-um graded-index multimode fiber. Target applications are short-reach data transmission for rack-to-rack application and links inside large data centers and storage area networks (SANs) in the computer and network industry.

The VCSEL transmitter module is equipped with a 60-GHz V-connector for the electrical input signal and operating current. The optical connector is specified as standard FC/PC connector. The transmitter provides a maximum optical output power of 1.1 mW at 2 mA with an operating voltage of 2 V. The module footprint is 34.5x16.7 mm with a height of 8 mm. The R40-1300 receiver is designed as a small form factor receiver optical subassembly (ROSA) which is available as fiber-coupled device with a test board.

The R40-1300 receiver includes a PIN photodetector with an input wavelength range of 900–1350 nm and a transimpedance amplifier (TIA) in a high-frequency TO-style micropackage. The TO-style receiver is coupled with a 50/125-um multimode fiber. The dimensions of the fiber-coupled assemblies are 6x6 mm and the overall length including a plastic boot for strain relief of the optical fiber is 40 mm. The R40-1300 module is available with high-speed adapter board with electrical differential signal output through 2.92-mm high-frequency connectors.

Both new devices will be on display at the upcoming Photonics West exhibition on Feb 4–6, 2014, in San Francisco, CA.
