Optical transceivers

The SYNOXX ESP852X-01D is a 25G SFP28 SR optical transceiver delivering 25.78Gbps 
transmission over multimode fiber — up to 100m on OM4, 70m on OM3, and 20m on OM2 
— using an 850nm VCSEL laser and PIN photodiode, purpose-built for high-density 25G 
Ethernet switching, 5G CPRI fronthaul, and 100G breakout target deployments. 
Features a hot-pluggable SFP28 form factor, LC duplex connector, and Digital 
Diagnostic Monitoring (DDM) via SFF-8472, with low power consumption and compliance 
with IEEE 802.3cc and SFF-8402 standards. Hot-pluggable, RoHS compliant, and IC 
Certified.

The SYNOXX ESP31X-20D is a 10G SFP+ LR optical transceiver delivering 10Gbps data 
transmission over single-mode fiber (SMF) up to 20km using a 1310nm DFB laser 
transmitter and PIN photodetector receiver. Supports Digital Diagnostic Monitoring 
(DDM) for real-time parameter tracking, with under 1W power consumption, LC duplex 
connector, and compliance with SFF-8431, SFF-8432, SFF-8472, and IEEE 802.3ae 
standards. Hot-pluggable, RoHS compliant, and IC Certified for Canada and the US.

The SYNOXX ESP85X-03D is a 10G SFP+ SR optical transceiver delivering 10Gbps 
transmission over multimode fiber (MMF) up to 300m using an 850nm VCSEL transmitter 
and PIN photodetector — purpose-built for high-density, short-range data centre and 
enterprise fiber links. Supports data rates up to 10Gbps with Digital Diagnostic 
Monitoring (DDM), all-metal housing for EMI protection, and compliance with IEEE 
802.3ae and SFF-8431 standards, with power consumption under 1W. Hot-pluggable, 
RoHS compliant, and IC Certified.

The SYNOXX EB3512-3D/EB5312-3D is a matched pair of 1.25G SFP BiDi transceivers 
that delivers Gigabit Ethernet and Fiber Channel connectivity over a single strand 
of OS2 single-mode fiber up to 3km — halving fiber count compared to duplex SFP 
modules by using wavelength-division multiplexing (WDM) with a TX1310nm/RX1550nm 
transmit-receive wavelength pair on each fiber strand. Compliant with SFP MSA and 
SFF-8472 standards, featuring LC simplex connectors, Digital Diagnostic Monitoring 
(DDM) for real-time temperature, voltage, and optical power monitoring, and a 3.3V 
operating supply. Hot-pluggable, RoHS compliant, and IC Certified.

The SYNOXX ES-T2-R is a 1000Base-T SFP copper transceiver delivering tri-speed 
10/100/1000Mbps Ethernet connectivity over standard Cat5 twisted-pair cables up to 
100 metres — enabling 1G copper uplinks on any SFP-equipped switch or router without 
fiber or media converters. Features a hot-pluggable SFP form factor, RJ45 connector, 
SGMII interface, fully metallic low-EMI enclosure, and low power consumption of 
~1.05W, compliant with IEEE 802.3 and SFP MSA standards. Hot-pluggable, RoHS 
compliant, and IC Certified.

The SYNOXX ESP3112-20D is a 1.25G SFP LX optical transceiver delivering Gigabit 
Ethernet and Fibre Channel connectivity over single-mode fiber (SMF) up to 20km 
using a 1310nm FP laser transmitter — the standard long-reach 1G fiber module for 
campus backbone links, building-to-building connections, and metro-edge deployments 
where multimode fiber falls short. Features Digital Diagnostic Monitoring (DDM) with 
real-time temperature, voltage, TX/RX power, and bias current monitoring, plus PIN 
photodiode receiver with integrated TIA and MCU control, compliant with SFP MSA and 
SFF-8472 standards. Hot-pluggable, RoHS compliant, and IC Certified.

The SYNOXX ESP8512-055D is a 1.25G SFP SX optical transceiver delivering Gigabit 
Ethernet and Fibre Channel connectivity over multimode fiber (MMF) up to 550 metres 
using an 850nm VCSEL transmitter — the standard choice for access-layer 1G fiber 
links and 1G Fibre Channel connections over OM2, OM3, or OM4 multimode infrastructure. 
Supports data rates up to 1.25Gbps with Digital Diagnostic Monitoring (DDM), PIN 
photodetector receiver, and compliance with SFP MSA and SFF-8472 standards, with low 
power consumption and a standard LC duplex connector. Hot-pluggable, RoHS compliant, 
and IC Certified.
