Loopbacks
Compact test loopbacks for commissioning and fault-finding on transceivers and active ports. A loopback returns a port's transmit signal to its own receiver, so technicians can test optics without a far-end partner.

Features
- Test optics without a far-end partner
- Cord-loop or moulded compact types
- Single-mode and multimode
Applications
- Transceiver testing
- Switch-port testing
- Commissioning & fault-finding
