Combining Utah Scientific’s award-winning flex cards with SFPs, the UTAH-400 Series 2 routers support fiber, A-D analog video, D-A analog video, HDMI, and DVI formats. You can mix and match any of the SFPs to create up to 12 inputs or outputs (in pairs) of mixed formats.


The card’s fiber inputs receive optical signals and convert them to SDI; conversely, the outputs take SDI and convert it to optical signals. Both single- mode and multimode fiber is supported, making this capability especially useful on long cable runs.


The card can also convert composite analog video input signals to SDI, and the outputs can convert SDI signals to composite. This is especially valuable when switching a small amount of analog video. In the same manner, the card converts HDMI and DVI input signals to SDI and the outputs can convert SDI to HDMI or DVI. This is useful for adding monitors to the router. With these capabilities, together with Utah Scientific’s XFD fiber and coax distribution products, the router becomes the hub of a complete optical routing system.

Technical Specs

This card is designed to receive 12 individual differential pair data streams at data rates between 3 megabits per second to 3 gigabits per second. This range allows the card to receive SMPTE SDI signals in the 259, 292, and 424 standards as well as non-SMPTE standards like DVB-ASI, AES-3 audio, and SMPTE-310 signals.


This card is to be plugged into a rear panel slot that is occupied with either a fiber optic input rear panel or a Differential Pair IO rear panel. The fiber optic rear panel can be
fitted with fiber optic transceivers and used to receive signals over single mode fiber. The differential pair input rear panel is used when the router system is fed with DAs from the UT100/3 series.

Circuit Description

After the 12 differential pairs enter this card from edge connector J1, the signal enters a 1 x 4 fanout distribution stage. One of these four signals is driven to each individual crosspoint in the system. In this fashion, every crosspoint card has an identical copy of each input signal in the system.

Controls and Indicators

Controls: P1 Standard UT400 diagnostic port that provides detailed operational status and control for this card



Communications indicator – Yellow, illuminated when the card has been addressed by the Frame Controller Module

PS Fail LED – Red. Illuminated when the 3.3V power supply falls out of + 5% tolerance

Signal Present Detection LEDs (12) – Green. One of these LEDs is present on the front edge of the card for each input signal. They are labeled as ‘Carrier Detect’ 1-12. These LEDs are only illuminated if a Fiber IO rear panel is fitted, and the Fiber SFP modules report that they are receiving an optical carrier. If no carrier is present, or in the case of a differential pair input signal from a DA, these LEDs will not be lit.
