Description

SC MM Fiber Optic Loopback module patch cable OM1 62.5 / 125 , OM2 50 /125 LSZH With Black Plastic Shell

Fiber Optic Loopback modules are also called optical loopback adapters. They are designed for testing, engineering and the burnin stage of boards or other equipment. Optical loopback adapters provide system test engineers a simple but effective way of testing the transmission capability and the receiver sensitivity of network equipment.

Fiber Optic Loopback is providing a media of return patch for a fiber optic signal. Typically it is used for fiber optic testing applications or network restorations.

When used in testing applications, loopback signals are used for diagnosing problems. The best practice is to send a loopback test to network equipment, one at a time for isolating the problem.

Fiber optic loopbacks are designed in a compact footprint. They are compliant with fast Ethernet, fiber channel, ATM and Gigabit Ethernet.

Mini SC loopback is suit for 0.9mm cable and 0.25mm fiber.

Connector’s Standard:

SC: TIA/EIA, FOCIS3, GR-326.NTT-SC IEC61754-4 and JIS C5973.

Which to Choose for a Specific Transceiver?

Considering the common features of the transceiver and the loopback, we should think about the connector type, polish type, and cable type when selecting a loopback for the transceiver. The selection guide for some mostly used transceiver modules is summarized in the following tables.

Table 1: Loopback choices for 10G SFP+ transceivers

Model Interface type Cable Type Suited Loopback
10GBASE-USR LC Duplex (PC) MMF LC/UPC Duplex Multimode Fiber Loopback
10GBASE-SR LC Duplex (UPC) MMF
10GBASE-LR LC Duplex (UPC) MMF
10GBASE-ER LC Duplex (UPC) SMF LC/UPC Duplex Single-mode Fiber Loopback
10GBASE-ZR LC Duplex (PC) SMF
