Transition Networks unveils extended temp, Cisco-compatible SFP transceivers

JANUARY 10, 2010 -- Transition Networks Inc., a wholly owned subsidiary of Communications Systems, Inc. (NASDAQ: JCS), has introduced a new family of small form factor pluggables (SFPs) with industrial operating temperature range. The new SFP transceivers are designed for bi-directional data communication with transmission speeds of up to 1.25 Gbps, which is compliant with IEEE 802.3z Gigabit Ethernet standard.

The new SFP transceivers offer an extended operating temperature range from -40 to 85 degrees C. This makes them ideal for field deployment in factory floor, outdoor networks, and any non-climate controlled environment, according to the company. The new SFP transceivers can be used in any MSA-compatible networking equipment used in industrial-rated environments and can also be used in any Cisco switches that support Cisco original SFPs, Transition Networks adds.

The transceivers support Digital Diagnostics Function (DMI) which is standardized by the SFF Committee under SFF-8472. This function provides real-time measurements of the laser bias current, transmitted optical power, received optical power, internal transceiver temperature, and the supply voltage. DMI allows the end users to implement reliable performance monitoring of the optical link in a very accurate and cost-effective way.
Transition's newest extended temperature SFP pluggable optics are available immediately. They are available in multimode 1000Base-SX and 1000Base-LX models. The 1000Base-LX transceivers can transmit up to 80 km on singlemode fiber for Gigabit
