Looks like this one -CISCO 1000BASE-LX/LH GBIC
According to this page.
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_data_sheet09186a008014cb5e.html

Here is the compatability matrix:

Do you have to do single mode?  300 Meters isn't very far - Multimode could do it, and would be cheaper.

You can do single mode but why would you when Multimode is 1/2 the cost.... just a thought ...

Thanks

Well, they might have single mode already pulled - so then they're stuck.

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

Single mode as long as it is not a very short distance (under 300 meters) should not be a problem at all.

Thanks

There is your link I would say it also depends on your fiber pulled.... but sure..

Thanks

Yes, that's the way I read the following text below.  I don't think you need or want to pay for hte ZX.  Contact your local authorized Cisco Reseller (VAR) to be sure.  I'm sure they'd love to come meet with you and set up a relationship and answer this simple (for them) question.

CISCO 1000BASE-LX/LH GBIC

The Cisco 1000BASE-LX/LH GBIC (WS-G5486) fully complies with the IEEE 802.3z 1000BASE-LX standard. However, its higher optical quality allows it to reach 6.2 miles (10 kilometers) over single-mode fiber (SMF), compared with the 3.1 miles (5 km) specified in the standard.
CISCO 1000BASE-ZX GBIC

The Cisco 1000BASE-ZX GBIC (WS-G5487) operates on ordinary single-mode fiber optic link spans up to 43.4 miles (70 km) long. Link spans of up to 62 miles (100 km) are possible using premium single-mode fiber or dispersion shifted single-mode fiber. The GBIC provides an optical link budget of 23 dB-the precise link span length will depend on multiple factors such as fiber quality, number of splices, and connectors.
When shorter distances of single-mode fiber are used, it might be necessary to insert an in-line optical attenuator in the link to avoid overloading the receiver:
• A 5-dB or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the Cisco 1000BASE-ZX GBIC at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).
