Overview
The Symmetric 10G EPON ONU SFP+ Transceiver is an advanced optical module designed for the subscriber side of high-performance Ethernet Passive Optical Networks. Unlike asymmetric models, this transceiver delivers 10 Gbps speeds in both directions (downstream and upstream), making it the ideal solution for enterprise connectivity, mobile backhaul, and high-end residential services requiring massive upload bandwidth.
Adhering to the IEEE 802.3av (10GBASE-PR30) standard, this module supports a symmetric 10.3125 Gbps data rate. It features a robust PR30 optical power budget, allowing for deployment in networks with split ratios up to 1:64 and distances up to 20km. The unit utilizes a precision BOSA component to transmit data upstream at 1270nm while receiving downstream data at 1577nm, ensuring full-duplex operation over a single fiber strand.
Key Features

Symmetric vs. Asymmetric 10G EPON
While Asymmetric modules (10G/1G) are sufficient for typical home streaming, the Symmetric 10G EPON ONU is built for the future. As user generated content, cloud computing, and peer-to-peer applications grow, the upstream bottleneck of 1G becomes a limitation. This symmetric module removes that barrier, unlocking the full potential of the fiber plant. Note that your OLT (Headend) must also support Symmetric 10G EPON line cards to utilize this module.
FAQ (Technical & Product Questions)
1. What wavelength does this symmetric module use?
It uses 1270nm for upstream transmission (Tx) and 1577nm for downstream reception (Rx). This differs from asymmetric modules which typically use 1310nm for upstream.
2. Can I use this module on an Asymmetric OLT port?
Generally, no. The OLT port must be configured for and capable of Symmetric 10G operation. While some dual-rate OLTs exist, you should verify that your specific OLT line card supports the 1270nm upstream receiver.
3. Does this SFP+ work in a standard Cisco/Juniper switch?
It fits physically, but the switch must support EPON MAC layer functionality. Most standard data center switches are “Active Ethernet” (P2P) and do not understand the EPON protocol. This module is intended for devices specifically built as ONUs or switches with PON-aware software.
4. What is the connector polish type?
The module interface is SC/UPC (Blue). Ensure you do not force an SC/APC (Green) connector into it, as this causes an air gap and high signal loss. If your wall jack is APC, use a UPC-to-APC patch cord.
5. Is this compatible with GPON or XGS-PON?
No. 10G EPON is an IEEE standard, while GPON and XGS-PON are ITU-T standards. They use different framing protocols and are not interchangeable.
