The document describes the features and characteristics of the E-TBT-FRL-1200, E-TEL-FRL-1200, and E-TBT-FRL-0600 series multi-port media converters with LinkAlert™. These converters allow network administrators to extend distances between sets of 10BASE-T and 10BASE-FL devices in large and complex networks.
The E‑TBT‑FRL‑1200, E‑TEL‑FRL‑1200 and E‑TBT‑FRL‑0600 series are rack‑mountable multi‑port media converters that extend distances between 10BASE‑T copper and 10BASE‑FL fiber links. Each unit provides independent converter connections (12 ports for the 1200 models, 6 ports for the 0600) and includes the LinkAlert™ feature for automatic link‑fault propagation.
The manual covers installation (rack mounting or tabletop), cable and connector options, technical specifications, power requirements, LED status indicators, and a step‑by‑step fault isolation guide. Detailed fiber‑optic and copper‑cable specifications, as well as switch settings for enabling or disabling LinkAlert, are also provided.
| Standards | IEEE 802.3 1998 Edition |
|---|---|
| Case Dimensions | 19.0" x 8.5" x 1.5" (483 mm x 216 mm x 38 mm) |
| Operating Temperature | 0‑50 °C (32‑122 °F) |
| Storage Temperature | -15‑65 °C (5‑149 °F) |
| Humidity | 10‑95 % non‑condensing |
| Altitude | 0‑10,000 ft |
| Power Input | 100‑240 VAC, 50/60 Hz, max 1 A |
Use the 2‑position switches on the front of the unit; Switch 1 controls ports 1‑3, Switch 2 ports 4‑6, Switch 3 ports 7‑9 (12‑port unit), and Switch 4 ports 10‑12. UP enables LinkAlert, DOWN enables standard link integrity test.
The device operates from 100‑240 VAC, 50/60 Hz and draws up to 1 A maximum.
Typical maximum distance is up to 20 km for single‑mode fiber with a 7 dB link budget.
The T(wisted)P(air) LED stays steady when a good link is present on the copper side.
