Description

Dual-head conversion lead designed to adapt SMB clock/timing ports to standard BNC interfaces for test gear or network timing on carrier circuits. 75‑ohm coax construction ensures proper impedance matching for T3/E3 and timing applications.

Features

- Dual SMB-to-BNC conversion for timing/clock applications
- 75Ω impedance for T3/E3 and test/lab compatibility
- Shielded coax for low noise and signal integrity
- Passive design—no external power required
- Rugged molded connectors for durability
- Broad compatibility with timing analyzers and carrier gear

FAQs

Q: What equipment is this cable typically used with?
A: It adapts SMB clock/timing ports to BNC, commonly for carrier T3/E3 timing, lab analyzers, and network test equipment.

Q: Is it 50Ω or 75Ω?
A: It is intended for 75Ω environments, matching T3/E3 and timing applications that use 75‑ohm coax and BNC connectors.

Q: Does it carry data or only timing signals?
A: It’s generally used for timing/clock I/O, but it can carry any signal appropriate for 75Ω coax at the required frequency.

Q: Are the SMB connectors male or female?
A: Both SMB connectors are male; both BNC connectors are male.

Q: Is it active or passive?
A: This is a passive conversion lead; no electronics are involved.
