A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. Developed in the late 1980s, the erbium-doped fiber amplifier (EDFA) was the first successful optical amplifier. See EDFA.

Of course, to enjoy all surround sound has to offer, you'll...

- As one of America's oldest audio brands, it was inevitable Marantz would offer a single-speaker surround system.

- Panasonic is hardly the first name we think of when it comes to AV receivers. It's been years since we last saw one, so we weren't sure what to expect from Panasonic's latest entry, the SA-BX500. Depending on your taste, the look is tastefully conservative or just downright boring. The...

The TZ512 also offers a few additional audio inputs as well as compatibility with various digital file formats. The HT-X710T, reviewed here, keeps most of...

- Samsung HT-TZ512T
- In terms of value, it's hard to beat a home-theater-in-a-box HTIB system. While these systems have long bundled the home theater basics--DVD player, amplifier, and surround-sound speakers--into one package, manufacturers have continually upped the ante in recent years with more and more features. Samsung's HT-TZ512T is an excellent case in...

- Samsung HT-X810T
- If the primary appeal of soundbar speakers is based on their significant reduction of wires and clutter--as compared with 5.1-channel home theater-in-a-box systems--then Samsung's new HT-X810T soundbar should be a winner. While it's not the first single-speaker system with a built-in DVD player or a wireless subwoofer--that'd be the Philips...

- When we looked at last year's TH-L1 from JVC, we were really impressed at the number of connectivity options the compact 5.1-channel home-theater-in-a-box HTIB packed in its tiny chassis.
