| MODEL
LMSXA/SXB-1R |
Bi-directional 10Base-T Ethernet /
100Base-T Fast Ethernet Data over
One Multimode or Singlemode fiber |
|
| DESCRIPTION
The SD series Ethernet transceiver is a single-slot module and is designed for bi-directional transmission of 10/100 Base-T Ethernet data over one multimode or singlemode fiber. Since the data rate is auto-negotiated, no internal adjustments or
setting are necessary. Distances of 50km can be obtained using singlemode fiber. The SD series is environmentally hardened and will operated over the standard NEMA TS-2 temperature range - suitable for outdoor installations. LEDs on both
the module and rack card indicate power, link speed, activity, laser current and optical signal status. Standard shielded RJ- 45 connectors are provided for Cat. 5 compliance. Optical connector
options include ST, FC and SC. These units are available in either module or rack mount types. The SD series is also compatible with Lascomm's SpectraSmart Network management and diagnostic PCbased system. See the SpectraSmart brochure for additional details.
