Dahua compatible GSFP-1310-20-SMF Description

EdgeOptic's GSFP-1310-20-SMF compatible is a Dahua-coded version of the EdgeOptic 1.25G-SFP-20DI multi-vendor Gigabit Ethernet SFP transceiver. GSFP-1310-20-SMF is the Dahua part number for a duplex single-mode LC module operating at 1310nm on transmit and receive, rated for 20 km of single-mode fiber with a 13 dB average link budget.

The module uses an FP laser transmitter and a PIN photodiode receiver, tuned to a 100nm passband from 1260 to 1360nm centered on 1310nm. Transmit power ranges from −9 dBm to 3 dBm, receiver sensitivity is −22 dBm with a −3 dBm overload point, and chromatic dispersion is specified at 140 to 160 ps/nm. Digital diagnostic monitoring is supported per SFF-8472, reporting Tx/Rx power, bias current, voltage and temperature on any host platform that reads standard SFP DDM registers. The module also supports 1G Fibre Channel at 1.0625 Gbps alongside 1.25 Gbps Gigabit Ethernet, so it drops into either application without a different part number.

The transceiver runs on a +3.3V supply and complies with CE, FDA and IEC 60825-1 Class 1 laser safety, RoHS, and the SFP MSA form factor specification (INF-8074i).

EdgeOptic's compatible module carries an industrial temperature rating of −45°C to +85°C. Dahua's own GSFP-1310-20-SMF module is rated −40°C to +85°C on Dahua's official product page, a narrower window that the EdgeOptic compatible module meets and exceeds.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the module ships next business day from EU stock with a lifetime warranty. For project quantity pricing or alternative vendor coding, contact our sales team.

Frequently Asked Questions

What is the difference between the Dahua GSFP-1310-20-SMF and the GSFP-1310R-20-SMF / GSFP-1310T-20-SMF?

GSFP-1310-20-SMF is a duplex module using single mode double fiber with 1310nm on both transmit and receive, on separate LC connectors, per Dahua's own product page. Dahua also lists R- and T-suffixed GSFP-1310 variants (GSFP-1310R-20-SMF, GSFP-1310T-20-SMF) as separate part numbers that may use a different fiber type. Verify the fiber type and wavelength plan against Dahua's own product page before ordering, and do not substitute a single-fiber BiDi module for this duplex part or the fiber pairing at each end of the link will not match.

What operating temperature range does the Dahua GSFP-1310-20-SMF support?

Dahua's own GSFP-1310-20-SMF module is rated −40°C to +85°C on Dahua's official product page. EdgeOptic's compatible is built to an industrial temperature rating of −45°C to +85°C, which covers and exceeds Dahua's own rating.
