Technical FAQ — Optical Transceivers

What is an optical transceiver and what are the main types?

An optical transceiver converts electrical signals into optical signals, used in data centers and enterprise networks. Main types: SFP/SFP+ (1G/10G), QSFP+ (40G), QSFP28 (100G), QSFP56 (200G), QSFP-DD/OSFP (400G/800G).

How do I choose the right optical transceiver?

Consider: transmission speed (10G/100G/400G), distance (SR/LR/ER/ZR), connector type (LC/MPO), wavelength (850nm/1310nm/1550nm), and compatibility with your device brand.

How are transceivers classified by transmission distance?

SR (≤100m, multimode), LR (≤10km, single-mode), ER (≤40km), ZR (≤80km). Actual range depends on fiber type and connector quality.

What is a compatible transceiver vs. OEM module?

Compatible transceivers are third-party modules programmed for specific brands (Cisco, Juniper, Huawei). They offer equivalent performance at 30–70% lower cost than OEM modules.

How do I verify compatibility with my device?

Share your device model and firmware version with our team, check our compatibility list, or request a free compatibility test. We offer a 30-day return guarantee.

How do I troubleshoot a transceiver issue?

Check seating in port, verify TX/RX power with an optical power meter, clean fiber connectors, use CLI to check module status (e.g., show interface), or contact our support team.
