Transition Networks Launches Gigabit Ethernet PoE+ Media Converters with Small Form-Factor Pluggable Optics

Offers Flexible Optical Connection Ideal for Connecting Remote Workgroups, IP Phones, Pan-Tilt-Zoom Surveillance Cameras, or High Bandwidth Wireless Access Points

Minneapolis, MN – September 11, 2017 — Transition Networks, Inc., a leading provider of innovative, high-value, data network integration solutions, today announced its new family of 10/100/1000 Ethernet small form-factor pluggable (SFP)-based enterprise-class media converters (SGPAT1040-x05) with Power-over-Ethernet Plus (PoE+). These products are new additions to the recently announced multi-port Gigabit Ethernet PoE+ family of media converters.

The SFP-based media converters connect a 10/100/1000Base-T network to a 100/1000Base-X fiber-optic network. The devices let network administrators easily and affordably support different types of optical network cabling and transmission distances. The SFPs can also be used to support different wavelengths if the fiber connection is going to a coarse- or dense-wavelength division multiplexer.

These devices deliver 30W power on each UTP port, which means they can accommodate devices with higher power requirements such as IP phones, pan-tilt zoom (PTZ) network cameras, and high bandwidth wireless access points (WAPs). In addition, the active link pass through (ALPT) and auto power reset (APR) features make it quick and simple for network administrators to manage link failures and power resets.

In addition to the single-copper / single-SFP converter, there are two additional versions including a three-port version (one copper RJ-45 and two fiber optic ports) supporting 100Base-X, 1000Base-X, or SGMII MSA-compliant SFP modules and a four-port version (two copper and two fiber optic ports) PoE+ SFP media converter.  These converters can be used to connect multiple remote systems to a switch or to connect to a switch with redundant fiber links. The dual optical ports can be enabled for redundancy, supporting both revertive and non-revertive operation. The four-port will also work as two independent media converters in one housing to save space.

“Earlier this year we announced the new SGPAT fixed-optics media converters to deliver flexibility in extending network connectivity while also providing PoE+ and network intelligence,” said Curt Carlson, Product Manager with Transition Networks. “Now with the availability of the SFP-based versions, we’re able to deliver even greater flexibility for different fiber connections used in fiber-to-the-desk connectivity or to connect remote devices such as security cameras or wireless access points.”

The SFP media converters support SGMII-based copper SFPs, as well as 100 or 1000Mbps fiber SFPs.  The converter is also compliant with the IEEE 802.3at PoE+ standard. The converters are designed for table-top installations, but also support options for mounting on a wall or DIN Rail, and leverage an external AC/DC power supply for higher reliability.

The SFP SGPAT1040-x05 media converter is part of the SGPAT10xx-105 family of media converters announced recently. All versions of these media converters are now available.
