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.
| Part Number | Connector Type | Polish Type |

| GP-3208 | FC | APC (8° angled) or UPC |
Please select the correct connector type (SC or FC) and polish type (APC or UPC) to match your fiber network when ordering. If unsure, contact us before ordering.

The Swap-Out Connector system is specific to the EXFO MaxTester 700D series. It is not compatible with older MAX-715B, MAX-720B, or FTB-series OTDRs, which use the EUI-series adapter system.
| Polish Type | End-Face Angle | Typical Return Loss | Common Applications |
|---|---|---|---|
| APC | 8° angled | >60dB | FTTH / PON networks, CATV, long-haul telecom |
| UPC | 0° flat | >50dB | Enterprise fiber, data centers, telecom OSP |
Important: APC and UPC connectors are not interchangeable. Always match the Swap-Out connector polish type to your fiber network’s connector type.
