What are the main types of optical transceiver modules?

The main types include SFP (1G), SFP+ (10G), SFP28 (25G), QSFP+ (40G), QSFP28 (100G), QSFP56 (200G), and QSFP-DD (400G). Each adheres to IEEE 802.3 standards for Ethernet transmission and uses standard LC or MPO interfaces per IEC 61754.

What is an optical transceiver module and how does it work?

An optical transceiver converts electrical signals into optical signals for fiber transmission and reconverts them back to electrical at the receiver end. It contains a transmitter (laser/VCSEL) and receiver (photodiode) following Telcordia GR‑468‑CORE optical reliability tests.

Which standards define optical transceiver performance?

Transceivers comply with IEEE 802.3 Ethernet protocols, ITU‑T G.957/G.695 for optical interfaces, IEC 60825‑1 for laser safety, and Telcordia GR‑468‑CORE for environmental and lifetime testing. Module housings also follow SFF or CFP/MSA specifications.

What are the typical transmission ranges of optical transceivers?

Distance depends on module type: SX up to 550 m (OM3), LX up to 10 km, EX up to 40 km, ZX up to 80 km, and DWDM transceivers > 100 km. Single‑mode versions (G.652D/G.657A1) cover long ranges under ITU‑T G.698.

What interfaces are used by optical transceivers?

Standard connectors include LC duplex for SFP and QSFP single‑mode modules, and MPO/MTP for parallel multimode (40G/100G). Optical fiber compatibility follows IEC 61754 and TIA‑568‑C.3 polarity specifications.

Which optical transceiver module should I choose?

Select the module based on data rate, distance, and connector type: for short multimode links use SFP+/QSFP+ SR (OM3/OM4); for long reach use LR or ER (OS2). Ensure conformance with IEEE 802.3 and Telcordia GR‑468 for long‑term reliability.
