OCP adds DWDM, supervisory channel SFP transceivers

Sept. 22, 2006
SEPTEMBER 22, 2006 -- Optical Communications Products Inc. (OCP) has announced the availability of its 180- and 200-km OC-48/STM-16 DWDM small-form-factor pluggable (SFP) transceivers for high-density, long distance MAN applications. The company also has unveiled a 1510-nm Optical Supervisory Channel SFP transceiver.

SEPTEMBER 22, 2006 -- Optical Communications Products Inc. (OCP; search for OCP) has announced the availability of its 180- and 200-km OC-48/STM-16 DWDM small-form-factor pluggable (SFP) transceivers for high-density, long distance MAN applications. The company also has unveiled a 1510-nm Optical Supervisory Channel SFP transceiver.

"With the expansion of the DWDM SFP product portfolio, OCP is well positioned to support the growing WDM-based metro market. We are providing a comprehensive DWDM product line with 80-km, 120-km, 180-km, and 200-km product options now available," said Kirk Bovill, director of marketing at OCP, regarding the first announcement.

OCP's "TRPW48" DWDM product line is compliant with the G.692 ITU-T standard, offering 44 wavelengths on 100-GHz C-Band spacing with an optical link budget of 26 dB. The DFB lasers used in these SFP transceivers feature an integrated optical isolator for stable transmitter operation under the varying back-reflection conditions that exist in installed cable plants.

The modules are designed for multi-rate applications, supporting data rates ranging from 2.67 Gbits/sec down to 125 Mbits/sec. The DDM functionality adheres to the SFP DWDM MSA, enabling the end-user to monitor key areas in the performance of the SFP transceiver: internal temperature, DC supply voltage, transmitter bias current, transmitter output power, receive optical signal level, laser wavelength, and TEC current. Integrated DDM functionality also incorporates warnings and alarms to monitor these parameters.

Meanwhile, the Optical Supervisory Channel SFP transceiver is designed for FE/OC3/STM-1, low-speed 50-155 Mbd, OSC applications for use in WDM systems.

"This device provides an excellent optical link budget of 44 dB using a 1510-nm DFB and a high-performance APD receiver. We are well positioned to support the growing WDM-based market and this device provides a flexible, easy to use and reliable interface for optical supervisory channel applications in WDM systems in a pluggable format," said Bovill.

The "TRPA03E2ZB" Optical Supervisory Channel SFP transceiver provides integrated digital diagnostics monitoring functionality via an I2C serial interface as described in the MSA document, SFF-8472 (Rev 9.4). The DFB laser used in this SFP transceiver features an integrated optical isolator for stable transmitter operation under the varying back-reflection conditions that exist in installed cable plants.

The new transceivers will be on display at ECOC 2006 in Booth 638.
