- Product Introduction
Inside the FB-LINK ZR4 Lite 40G QSFP+ 60km Single-Mode Long-Reach Transceiver
The FB-LINK 40G QSFP+ 60km transceiver carries a full 40 Gigabit link across 60 km of single-mode fiber using four CWDM channels multiplexed around the 1310 nm band. Four 10 Gb/s electrical lanes are combined into one 40 Gb/s optical stream for transmit, then optically de-multiplexed back into four 10 Gb/s lanes on receive, with no external mux and no line-card change. Built to IEEE P802.3ba as a 40GBASE-ZR4 Lite optical module in a standard hot-pluggable QSFP+ form factor with an LC duplex interface, this extended-reach 40G QSFP+ CWDM4 transceiver sits exactly between 40 km ER4 and 80 km ZR4: it clears long-haul metro spans that ER4 cannot reach, without paying the cost and power of full 80 km ZR4 optics.

Wholesale 40G QSFP+ 60km Transceiver Advantages for Project Buyers
Three procurement reasons buyers specify the FB-LINK 60km ZR4 Lite tier over the reaches on either side of it.
01 / REACH FIT
60 km reach closes the ER4 gap
ER4 tops out around 40 km; ZR4 targets 80 km. Metro rings, campus-to-campus and edge-to-core spans frequently land at 45–60 km - too long for ER4, wasteful on ZR4.
Specifying the 60 km ZR4 Lite tier means the link budget is engineered for the actual span, so you stop over-buying reach you'll never light.
02 / CWDM4 OPTICS
CWDM4 optics on one duplex fiber
4 × 10 Gb/s CWDM channels around 1310 nm ride a single LC duplex single-mode pair. One fiber pair per 40G link instead of four.
For a metro build, that quarters the strand count this link consumes - real savings when leased dark fiber is priced per pair.
03 / DROP-IN QSFP+
Drop-in 40G QSFP+ upgrade
Standard QSFP+ MSA footprint, hot-pluggable, IEEE P802.3ba compliant. It slots into the 40G QSFP+ ports you already have.
Coded to your switch vendor before shipment, so the extended-reach upgrade is a module swap - not a chassis or firmware project.
CWDM4 Optics and Signal Path Inside the 40G QSFP+ 60km Optical Module
How the FB-LINK 40G QSFP+ 60km optical module builds, carries and recovers the 40 Gb/s aggregate across a 60 km single-mode span.
TX
4 × 10 Gb/s → 40 Gb/s multiplex. Four 10 Gb/s electrical lanes drive four CWDM optical channels in the 1310 nm band, combined onto one single-mode fiber. Aggregating in the module means your host still sees a standard 40G QSFP+ port - no gearbox or external WDM to integrate.
λ
4 × 10 Gb/s → 40 Gb/s multiplex. Four 10 Gb/s electrical lanes drive four CWDM optical channels in the 1310 nm band, combined onto one single-mode fiber. Aggregating in the module means your host still sees a standard 40G QSFP+ port - no gearbox or external WDM to integrate.
BUDGET
+2 to +7 dBm launch, < −24 dBm sensitivity. The transmit/receive window is sized for a 60 km link budget with margin for connectors, splices and patch panels. Send us your span loss and we confirm the module clears it before you order - no guessing at the optical margin.
RX
Optical de-multiplex back to 4 lanes. On receive, the 40 Gb/s stream is split back into four 10 Gb/s electrical lanes and retimed. The full transmit and receive path lives on one module, so there is a single field-replaceable unit per end of the link.
Metro-Ready 40G QSFP+ 60km Transceiver for DCI and Carrier Network Projects
Where a FB-LINK 60 km extended-reach 40G QSFP+ transceiver is the right tool, straight from the module's rated application areas.
Metro Networks
Ring and point-to-point metro spans in the 45–60 km range where ER4 runs out of budget. One QSFP+ per site, single fiber pair per link.
Data Center Interconnect
Connect two facilities across town over leased single-mode fiber at 40G without renting a full ZR4 80 km link or a DWDM shelf.
Switch & Router Uplinks
Long-reach 40G uplinks between aggregation switches and routers on standard 40G QSFP+ ports - no new line cards.
Rack-to-Rack & Campus
Extended intra-campus and building-to-building links where copper and short-reach optics can't span the distance.
Custom OEM and ODM 40G QSFP+ 60km Transceiver Manufacturing for Project Buyers
If you're a sourcing manager standardizing a fleet, the FB-LINK 40G QSFP+ 60km transceiver ships coded to your switch platform out of the box. Specify the target vendor, whether Cisco, Juniper, Arista, Brocade, H3C or HUAWEI, and we program the EEPROM so the module registers as a native-compatible part on your line card.
Private-label programs are available: your part number, your label artwork, your box. For volume programs we align coding, firmware behavior and packaging to your acceptance test so incoming inspection passes on the first pass.

40G QSFP+ 60km Transceiver Procurement FAQs
Q: What is the maximum reach of the 40G QSFP+ 60km ZR4 Lite transceiver?
A: It is rated for 60 km over single-mode fiber as a 40GBASE-ZR4 Lite module. It uses four CWDM channels around 1310 nm multiplexed onto one LC duplex fiber pair, with a +2 to +7 dBm launch window and < −24 dBm receive sensitivity. Send your measured span loss and we confirm the budget clears before you order.
Q: Is this 60km module compatible with Cisco, Juniper or Arista switches?
A: Yes. FB-LINK, as a dedicated 40G QSFP+ transceiver manufacturer, codes each unit to your target platform and function-tests it on matching switch hardware before shipment. Specify the vendor and switch model with your order and the module registers as a native-compatible part.
Q: Should I choose 60km ZR4 Lite or 80km ZR4 for my span?
A: Match the module to the span. If your link is around 45–60 km, the 60 km ZR4 Lite tier is engineered for that distance and avoids the extra cost and power of 80 km ZR4 optics. If your span exceeds 60 km, step up to the 80 km ZR4. FB-LINK, as a 40G QSFP+ supplier carrying the full 10 / 40 / 60 / 80 km ladder, can quote both so you specify the right reach rather than over-buying.
Q: Does it drop into existing 40G QSFP+ ports without hardware changes?
A: Yes. It uses the standard QSFP+ MSA form factor and is hot-pluggable and IEEE P802.3ba compliant, so it fits the 40G QSFP+ ports you already run. The extended-reach upgrade is a module swap - no line card or chassis change required.
Q: Do you support OEM coding and private-label orders?
A: Yes. FB-LINK, as a 40G QSFP+ 60km OEM manufacturer with in-house coding and test, supports vendor programming, private-label part numbers and labels, custom DDM behavior and packaging to your acceptance standard. Batch serialization for traceability is available on production runs.
Q: What is the MOQ and lead time?
A: We support sample quantities for qualification through full production volumes. MOQ and lead time depend on your coding target and order size, so we confirm both in writing with your quote rather than posting a fixed figure. Share your vendor and quantity to get exact numbers.
