Sophos compatible ITFZTCHSX Description

EdgeOptic's ITFZTCHSX compatible is a Sophos-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850nm VCSEL transmitter and a PIN photodiode receiver.

With a 7.5 dB optical budget, the module reaches 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m over OM1 (62.5/125). It uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live monitoring of optical power, bias current, and temperature. The module operates over the commercial 0 to 70°C range, built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.

ITFZTCHSX is the Sophos ordering code for this 1G SX SFP. EdgeOptic codes the EEPROM with Sophos-recognized data so the module is identified correctly in SG UTM, XG Firewall, and XGS Firewall SFP ports, including FleXi Port expansion modules on applicable XGS models. Confirm the specific port support for your model in Sophos's own transceiver compatibility documentation before ordering.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ordering-code confirmation or platform questions, contact our sales team.

Frequently Asked Questions

Is the Sophos ITFZTCHSX the same as ITFZTCHLX or ITFZTCHLR?

No. These are different Sophos SKUs by reach and speed class. ITFZTCHSX is the 1000BASE-SX 850nm multimode short-reach optic (550m). ITFZTCHLX is a 1000BASE-LX 1310nm single-mode long-reach SFP, and ITFZTCHLR is a 10GBASE-LR 10G single-mode SFP+, both for longer distances over SMF. Do not substitute one for another. Verify the exact code for your required reach and speed, or contact our sales team and we will help match the right part.
