PRODUCT DESCRIPTION
TP-Link Gigabit WDM Media Converter (TL-FC311A-2) - 5 Years Local Warranty
The TL-FC311A-2 carries a full Gigabit link over a single single-mode strand at distances up to 2 km. It is the "A" half of a WDM pair — transmitting at 1550 nm and receiving at 1310 nm — and is the right choice for in-building and short campus runs where the 20 km version is more optical budget than the link needs.
Gigabit Over One Strand, Sized for Short Runs
The TL-FC311A-2 pairs a Gigabit SC fibre port with a 10/100/1000 Mbps Auto MDI/MDIX RJ45 port. Wavelength Division Multiplexing puts both directions on one strand of 9/125 µm single-mode fibre rather than the usual pair, and TP-Link rates this model to a maximum of 2 km. That covers a riser between floors, two blocks on the same site, or a run from a main distribution frame to a remote plant room — without paying for reach that will never be used.
Half the Fibre for the Same Link
In most buildings the constraint is not distance but available strands. Risers fill up, and pulling new fibre through an occupied building is expensive and disruptive. Because a WDM pair consumes one strand instead of two, a TL-FC311A-2 and its partner unit can double the number of Gigabit links an existing riser will carry. That is often the difference between adding a link this month and waiting for the next cabling project.
A and B Units Are Not Interchangeable
This is the A unit: 1550 nm transmit, 1310 nm receive. The far end must be the mirror image, and TP-Link names the TL-FC311B-2 as a product that cooperates with this model. Both ends must also share the same distance rating — a 2 km unit is not a partner for a 20 km one. Send us the model already installed at the far end and we will confirm the correct partner before you place the order.
Transparent, Silent and Wide-Range
There is no IP address, no web interface and no firmware to maintain: the converter is a transparent Layer 1 bridge with PWR and Link/Act LEDs on the front. At 94.5 x 73.0 x 27.0 mm and powered by a 5 V/0.6 A external adapter, it fits behind a patch panel or on a shelf. The published 0-50 °C operating range is wider than the 0-40 °C typical of TP-Link's desktop switches, which matters in an unventilated riser.
Ideal For
Singapore offices, campuses and industrial sites running Gigabit links between floors or nearby blocks over single-mode fibre, integrators conserving strands in a full riser, and IT teams completing an existing TL-FC311B-2 installation. Supplied by SourceIT with local Singapore warranty, GST invoice and project pricing on request.

Specifications are reproduced from TP-Link's published TL-FC311A-2 page. Note that TP-Link lists a shorter standards set for this model than for the 20 km TL-FC311A-20, which also names IEEE 802.3 and IEEE 802.3x; both are written as published rather than harmonised. No maximum power consumption, certification (Safety & Emission) row, Basic Function row, EAN or carton pack size is published for this model, so none is stated here.
Compatibility & Software Support
The TL-FC311A-2 is an unmanaged media converter. It is a transparent copper-to-fibre bridge with no controller, no web interface and no configuration.
| Omada SDN Controller | Not supported — this model cannot be adopted into an Omada Software, Hardware or Cloud-Based Controller and does not appear in the controller as a managed device |
| Omada App | Not supported |
| Management | None — unmanaged, plug and play. Status is read from the front-panel LEDs |
| Required Partner Unit | A WDM converter transmitting at 1310 nm and receiving at 1550 nm, at the same 2 km rating. TP-Link names the TL-FC311B-2 as a product that cooperates with this model |
| Fibre Plant | One strand of 9/125 micron single-mode fibre, SC connector, up to 2 km |
| Switch Compatibility | Any 10/100/1000 Mbps Ethernet switch or router port, including Omada and JetStream switches |

Frequently Asked Questions — TL-FC311A-2
What is the difference between this and the TL-FC311A-20?
Reach. This model is published at up to 2 km; the TL-FC311A-20 is published at up to 20 km. Both are A units transmitting at 1550 nm and receiving at 1310 nm. Keep both ends of a link on the same distance rating.
Which unit goes at the other end?
One that transmits at 1310 nm and receives at 1550 nm. TP-Link names the TL-FC311B-2 as a product that cooperates with the TL-FC311A-2. Two A units will not link to each other.
Does it need an Omada Controller?
No, and it cannot be adopted into one. The converter is unmanaged and transparent, and does not appear in Omada SDN.
What warranty does SourceIT provide?
Five years local Singapore warranty, under TP-Link's replacement warranty policy for media converters. Every TL-FC311A-2 sold by SourceIT comes with a GST invoice.
Is stock held locally?
Availability on this model is limited. Ask us to confirm current stock and lead time before you commit to a project date, and we can quote an equivalent current model if the timing does not work.
