EXFO OTDR Swap-Out Connector – GP-3207 / GP-3208 – SC or FC, APC or UPC – For EXFO MaxTester 700D OTDR series, including MAX-730D and MAX-715D, FTB-720D & 730D
The EXFO GP-3207 and GP-3208 are OEM Swap-Out Connectors for the EXFO MaxTester 700D OTDR series, including the MAX-730D and MAX-715D. Unlike traditional fixed OTDR optical ports, the MaxTester 700D’s Swap-Out connector system allows field technicians to replace the OTDR’s optical connector directly in the field — without sending the unit to a service centre — in seconds.
Advantage: the Swap-Out connector design enables iOLM support for both APC and UPC optical connectors. The internal connector is always APC, and always iOLM-compatible.
Note: UPC Swap-Out connectors will need to be replaced more often than APC Swap-Out connectors.
OX1 Click-Out connectors are NOT compatible with OTDRs. 700D OTDR Swap-Out connectors are NOT compatible with OX1.
Available in four configurations: SC/APC, SC/UPC, FC/APC, and FC/UPC.

APC vs. UPC: Which Connector Polish Do You Need?
| Polish Type | End-Face Angle | Typical Return Loss | Common Applications |
|---|---|---|---|
| APC | 8° angled | >60dB | FTTH / PON networks, CATV, long-haul telecom |
